Which Is the Best Aquarium Substrate For Your Tank?

[@AquariumCoop]

*What kind of substrate do you like to use, and what kind of plants and fish do you keep with it?*

[@IndoorEcosystem]

I generally find a mix of both works best. Depending on how you do your layout. Aquasoil is great but a bit expensive to fill an entire tank!

[@brianbrinegar6086]

75 gallon aquarium, Pool filter sand (Walmart), 10 mesh bags of Fluval soil under the sand. LOTS of plants. A tank full of Tetras - about 1 living plant per fish!

[@blujeans9462]

Newbie here: I am in the process of setting up my new tanks so I can't say if I'll be successful yet. But I have the supplies for doing a 3 layer planted tank: soil, sand, gravel.

[@IndoorEcosystem]

@@blujeans9462 I'm going to try that method soon as well. Going to be interesting.

[@shanes-aquatic]

I usually prefer a fine gravel. Not sand fine but not exactly what I'd call "gravel" size. Hard to explain. But no sharp edges because I almost always have some kind of sand sifter such as corydoras. I'd like to experiment with Fluval Stratum at some point but was worried about it lowering the ph of my water too much for what I was wanting to keep.

For my very first planted tank, I went with a deep substrate using Fluval Stratum for plants in mesh bags with a black and white sand cap. Im very happy with it and the growth on dwarf hair grass and cardinals (went with beginner plants) was near immediate....less than a week. My next "natural" project will be from a local pond with a higher elevation from any roads....with a sand cap and culture from that pond. No more gravel (only gravel) and plastic for me. Plants enable you to do many more things with an aquarium, because lets face it, you cannot achieve nature without them.

[@tjpatton8562]

I recently changed out the gravel in my 55 gallon planted community tank for Fluval Stratum. Plants are loving it, however I will warn that it is very effective at lowering ph and reducing KH to 0. So if you have naturally hard, high ph tap water like I do, you need to be careful doing large water changes because these levels will swing quickly and stress your fish.

[@seeing8spots]

No one warned me about the pH thing and my tap is 7.8. The tank I put stratum in is 6.2!

[@corymiller9854]

Indeed soil from your backyard is better if you have high ph and like hard water fish stay far away.

[@KasyMini]

I had a lot of problems early on with Fluval Stratum. I wasn't aware how much it could affect pH. In my first ever tank, I used a thick layer of this soil. The problem is, my tap water is very soft and has a neutral pH of 7, GH of 4 and KH of 1. I had pH swings like crazy and at some point, needed to do water changes twice a day to try and keep it to 6.8. It would lower to 6 or below. I since then added crushed coral and it has kept my pH stable at 7-7.2 In the other tanks that I had setup, I used less Stratum, only in areas where I was planting fast growing plants. For the rest of the substrate, I used Seachem Flourite. I still needed to add crush coral to keep the pH higher as it would be at 6.4 or less which isn't good for the types of fish and shrimps that I have.

[@lemonlizard1]

There are three necessary things to consider when deciding a substrate: 1. The fish's needs 2. The fish's colour 3. Plants 1. Are you planning on getting shell dwellers, cories or sand sifters? It may be better to stick with a sand or finer substrate 2. A blue fish will stand out in black substrate, a black fish will stand out in white substrate, etc. 3. Sand may not work as well as fluval stratum, or other planted substrates. A note on #3 is that you can always add a planted substrate under a bed of gravel/sand. We did this and it looks super natural. Sand and the plants are growing perfectly

[@Itsjustme-Justme]

In my opinion, the best way to go is an inert, fully natural, rounded and rather fine substrate. These are forever, you never need to replace them. How fine or coarse it should be, depends on the plants and fish you want to have. Very fine sand isn't good for plants because there's almost zero water cirdulation inside, no new nutrient and no oxigen reaches the root. Very coarse doesn't keep the roots in place and fish food sinks into it unreachable for the fish. Depending on the size of the fish, some medium sized gravels have a choking hazard. The most versatile typs is fine gravel or coarse sand, 0.5 - 2 mm in size, without extremely fine dust particles. The plants grow well in it and most species of fish do well with it too. Over time, it becomes kinda "active" by itself. Small amounts of organic matter constantly seep into it, decompose there and set free nutrients. The limited space between the small rocks keeps it seeping slow, it doesn't get as dirty as coarse gravel. When you have plants that need a lot of nutrients in the substrate, you can stick plant fertilizer to their roots. Active substrates that decompose or wear out have major flaws. They are not forever. You have to rip everything apart every couple of years, to replace the substrate. They cause a rollercoaster ride of PH and nutrient levels when you do a water change. When they are new they cause an overload of nutrients. Substrates with artificial color coating are bad because the coating wears down over time. They create micro plastic inside the aquarium. And their look is artificial. I'm sure that fish would't chose to live in a disney castle.

I recently re-setup my 17T and put a half-inch of fine white sand as the substrate.

For my plants, I am using a plant substrate in beakers that will be deeper than the sand and furnish a place for the plants to flourish. We shall see, as it has only been up a few weeks with only some plants. Planning on adding dwarf corys and endlers later this month. Hopefully with this setup everyone will feel at home and be happy. Take care.

[@KatieDeGo]

Pretty new in fishkeeping... is it bad to have anaerobic pockets, especially w planted tanks?

[@RZ350NC]

@@KatieDeGo Yes. Anerobic bacteria grow where there is no oxygen. If you see black patches in your gravel, they are growing there. They give off hydrogen sulfide gas (H2S) which is highly toxic. It is commonly called "sewer gas" and has a distinctive rotten egg odor. It is highly poisonous (if you can smell it, it is at harmful levels). Turning over your substrate or having a thin substrate helps prevent this condition. You want an aerobic (oxygen-filled) environment throughout your tank.

[@DreamPainter54]

@@KatieDeGo I'm also very new but from my understanding if there's pockets in the substrate and you disturb it (gravel vac or replanting or whatever) it releases ammonia and upsets the balance of the tank potentially killing off some friends along the way :/ but that's just my understanding I might be wrong!

Had eco complete gravel but my corycats weren’t as active as their are now come to find out that the gravel was scratching them up and causing red spots on their bellies. After switching to sand they were kinda jumping for joy and digging around and came out their little hide holes. I love sand cause it it feels so natural yes it’s a pain to clean but it makes feel more close to nature and most all fish will love it especially those that dig. I love how my trumpet snails emerge out the sand like little nocturnal zombies and then they disappear I also notice my betta scavenges around more and hangs at the bottom as she rests on the plants.😊

I generally go for natural/black river stone substrates or CaribSea freshwater planted substrates. I've managed to have plants grow just fine in both, and two of my best planted tanks, a goldfish tank (no longer sat up) and a betta tank (been up since September) don't have planted substrates. Goldfish had no fertz or root tabs, and the plants just exploded (easy to understand why that was the case). Betta tank has fertz and root tabs and, while not as fast as the goldfish tank, they're still growing quite well.

[@papagrande8374]

I have had moderate success with a base of small natural gravel on the bottom of my tanks capped with an inch or more of sand. I only have what you would characterize as “nano tanks”, the largest being a 14 gal cube. In that one in particular I’ve gone small natural gravel under the entire tank capped with a somewhat larger gravel for the back two thirds with a beach of sand covering the front third. The plants have been a mixed bag thus far over 6 months but I’ve had clear successes in the sand capped gravel. I suspect that will improve now that I’m incorporating grow tabs and liquid (Co-op) fertilizer (aside from the dissolved fish waste). I’ll add this as a “terrestrial” Rutgers certified master gardener of over 40 years. There is a soil correlation to what Cory says regarding the use of gravel as the planting base. That is potted and soil grown plantings benefit from “space” in the soil for root growth. Compacted clay for instance, like sand at your favorite beach, is not conducive to root growth in plants. Thus gardeners and farmers dealing with compacted soils incorporate various other materials (organics that slowly dissolve) by tilling and such to change that compacted “soil structure”. These techniques do a number of things that promote plant growth and root growth in particular. One important aspect is the break up of the compacted particles, providing “space” for root growth. And that “space” between the substrate particles, gravel in this aquatic case, helps create a superior planting substrate. Roots need space. This is also why stem plants often root like crazy when floated. There is virtually no resistance to root growth and so the plant takes advantage.

I saw someone on KZbin that used a Lego mat for divide the sand or rock to make a design. So since your a real fish guy and enjoy your videos I like to ask you. Also what fertilizer do I get for the plants that's not expensive. That's safe for fish and snails and shrimp

My 4ft has crushed shell it came with it when I brought it secondhand, do you have any opinion on this ? From what iv seen it’s called shell grit and it normally used as chicken feed

[@xuetoile6113]

Hi hi, my substrate disintegrates, the water gets muddy and the plant leaves get dirty, does it mean I need to change all the substrate every six months? Many thanks

[@dcphifer4307]

Thanks Cory. I need some Crushed Coral. The one pet store talked me out of it. Hmm. Why? I have a few Nerite Snails, a few Ghost Shrimp, and my water is hard. I save my Egg Shells for the birds. I clean and crush them.

[@glassyGREEN_]

So many options 😵‍💫

[@skyelee9398]

Very informative video. Thanks. Greetings from Oceanside California 🤙

[@ryanwaidalowski9221]

I am setting up a 150 thinking about Oscar’s to start any ideas gravel or sand ? Thank you

[@stevef3521]

Depends on filtration. Look into a fine river gravel, maybe by CaribSea. Sand can easily be kicked up and ruin filter impellers. Also, the aforementioned gravel will hide the poo better and allow for quick gravel vacuuming, making maintenance easier.

[@annelynncroft4757]

What do you sagest for a 55gal planted betta tank?

[@marcusstevenson1654]

I have always wondered, why is there so much footage of places like Petco/Petsmart in your videos? Where does it come from?

[@Sachinraik]

Hi what would be best substrate for a gold fish tank? No plants at all.

[@johncrowell9014]

Cory have you ever tryed black medium blasting sand made for sandblasting?

[@duncanhill6854]

What about mixing sand with gravel to accommodate corydoros and plants at the same time?

[@johnmcdonald1810]

My Cory’s do fine with gravel

[@Thunderkorn]

I’ve had the best luck with Japanese contra soil.

I would have thought that sharper sand compacts less. When they lay railway tracks on rocks each has to have a minumum number of facets to stop compaction.

[@tomcrossan8263]

I use 3 to 4 inch's of kitty litter and crushed coral in my Cichlid tanks and have no problems. It is not expensive.

[@amoladsul5876]

I m just a beginner..Please suggest substrate for non planted cherry barbs... dimensions of tank are L 36 inch...B 12 inch ... W 15 inch. Thanks

[@ericesper348]

I breed Endless, long thin white cloud, several types of cool water tolerant barbs. I grow sag, val, anubias, pearl weed and crypts. Most of my tanks are 40 breeders and I have blasting sand media as a substrate. Roughly a third of my tanks have a small pebble lava rock. Ideally, I would like to find standard lava rock in a crushed form that would be affordable, but unfortunately I have not. The lava rock I'm using is not the standard, it is a light Brown in color, and it is incredibly light when I apply it from the local garden supply store in bulk a third of it is unusable. It floats. I have a 20 gallon sterlite van in my back yard and soak it for a couple days, net off the floaters and throw all of that in my landscaping, so it's not wasted. But I really would like to find standard black lava rock enough crushed about a quarter inch pebble size.

[@DoubleMcZombie]

Have you tried soaking the floating rocks for a while to see if they take on water like drift wood?

Question for the community: I am newer to the hobby- but how do I gravel vac and not mess up plant roots? Also, will gravel vacuuming release any yucky stuff from my substrate into the water? Thanks friends! 😊

[@Shadowbow1000]

Second this question! 3 months into the hobby!

[@DreamPainter54]

When I'm doing a heavy gravel vac I leave at least a couple inch border around the base of the plant and only lightly vac on the top if I'm worried about looks. I haven't had any problems doing it this way but my tank is also just about a year old so I'm still very new too! Good luck! 💙

[@prestonheitzman107]

When I use a vac, I only go along the surface of the substrate to collect any debris on top. I don't disturb more than the very top layer of gravel.

[@KatieDeGo]

@DreamPainter54 I didn't get a notification from your reply and just saw it. Thank you friend! Hope you're having a lovely day 💗

[@KatieDeGo]

@prestonheitzman107 I appreciate your reply! I apologize- I didn't get a notification. So even if I can see gunk pretty deep I should just let it chill for the anaerobic bacteria?

[@billwatkins1041]

Plain gravel. Some most tanks brown natural and one is black.

[@idio-syncrasy]

Very wise advice

[@FirstLast-numba1]

I use eco complete substrate and some of my plants (like dwarf hair grass) are pulled up out of the substrate really easily. Any advice?

[@stevef3521]

Try anchoring it with ceramic rings, or google plant weights. There’s a bunch on the market. Make sure they’re aquarium safe.

[@matthewblankenship7968]

And here I am with black diamond blasting sand in all my tanks lol lots of root tabs and have great results with easy grow plants ✌🏻

[@AquariumAficionado]

I just scaped my 75gallon with a 20lb bag of contrasoil as a base then 20lb bag of fluval stratum, a capping layer of black decorative rock, then another capping layer of black eco complete

[@bernandoturner4840]

Thanks Corey..😀

[@dfg297lpopdirk]

ok i get it but i can top off substrare with a sand layer

[@egorm-yw3eu]

Can anyone remind what the plant at 0:41 is?

[@AlpacaMade]

This is an excellent video on substrate! Thank you very much👍

[@duncanhill6854]

What about using crushed coral when the water has high pH and gH?

[@Moodymtmoon]

Can I change my substrate from colored cheap aquarium gravel to a more natural substrate in an existing tank?
