I'd recommend an air stone for additional agitation because keeping discus means higher Temps and at higher Temps there is even less dissolved oxygen then a cooler tank.

[@nzkm4053]

too much surface agitation will reduce co2 in water which will be bad for the plants

[@aquaticconceptsbringingwaterto]

Discuses have no particular environment other than the tank itself. Where they are located is adaptable to your situation. Discus can adapt to almost any environment as long as that environment has consistent elements of traffic, noise and your interaction with your fish. Maintenance, Water changes and feeding are all important activities that build trust. If you are netting your fish and scaring them more than necessary, each time you approach the tank your fish will be suspect about why. If you make the experience a good one you build trust. Plan long term for your fish so that they can continue throughout their life cycle to experience the same environment and not disrupt their life experiences and patterns. This is True with all Tropical fish but some more than others. Discus fish are in that category where great care in planning a safe and stable environment yields the best results. They are not that fragile, they just need your trust. Good Luck!

[@djperkins487]

So I came home today from 5 days away for a work trip…left all my tank lights off, but they had sunlight so there was some light for them throughout the day. Found all my fish were lethargic, and I couldn’t really figure out why. Did everything you did when you found your fish. I had no idea that the plants would take out all the oxygen until I saw your video tonight. Thank you so much for this video, and now I’ll remember this when I go out of town again!

[@fishtales2597]

Hi i found that surface agitation is one thing aquariums must have to disperse gases that get trapped. Ive had this happen to me with fish in my aquarium without plants, fish gasping is a common thing.... glad the fish are ok

[@MDFishTanks]

the thing is, an air pump is good for creating surface agitation, which is what then oxygenates the water. People think the air bubbles are creating oxygen, but they are out of the water way to fast to dissolve. So by adding the wave making creating huge amounts of surface agitation, am I not doing the same thing as an air pump? To be honest, I'm probably creating much more??

[@alecthenice8115]

I noticed plants still pearl with a ton of surface movement too

[@alecthenice8115]

@@MDFishTanks wave makers are much better, this is why salt water hobbyists don't consider a protein skimmer as adequate

[@treyreppe4348]

@@MDFishTanks at least in gas exchange columns we delt with when I was in school bubbling is more efficient (although surface agitation is more than sufficient). The gas exchange rate depends on the bubble size and time (smaller bubble exponentially increases surface area) so air stones are far from useless, especially if you get one that you can change the bubble size (usually a bit of sponge you can pinch smaller for smaller bubble size). The same principle is used with CO2 injection, thats why they have tiny bubbles (CO2 also has a higher capacity in water than oxygen)

[@traumahealingandprevention]

@@treyreppe4348 agree with you on this. @MD Fishtanks do you have access to the Ziss no clog air stone? Most of my tanks are cool water (67° to 75° F) and I can go old school (like 1920's dirted and the plants are the only filtration) because I have small dither fish that disrupt the surface tension and I program the lights to more efficiently utilize the naturally produced CO2. In discus tanks, which need to be closer to 82° to 86° F, they are going to exhaust the oxygen supply faster. A Ziss no-clog can easily be adjusted for tiny bubbles, and maximize your gas exchange without making the discus have to use up O2 by swimming harder against the flow.🤷‍♂️ Just a thought.

[@MatchuCT]

Must say that I really appreciate you showing us the "actual" lighting amount without exposure compensation by the camera. It's really helpful as if we were to match what WE see, our plants would die. lol

[@alexnoser6723]

I remember having my freak out moment when I had unplugged my power head during maintenance and forgot to plug it back in. I woke up in the morning and had this exact thing happen. (It’s scary!) Glad you got it worked out MD!

[@AquascapingCube]

Discus reaction to the tap in the glass was priceless :D

[@al44tec]

My discus just died 2 days ago. Didn’t give me any warning at all. I was baffled as well because my parameters were spot on. I’m guessing one of them died and just took the tank out. My best guess because there were no other issues up to them going belly up. Just something that sometimes happens in this hobby. We just do our best to give these fish the best lives we can. Had mine for a little over 5 years and been keeping discus for 25 years. Love those fish. Definitely worth all the effort but things can happen fast.

[@Cobra_Khan]

They’re not immortal, no matter how much we take care of them - sad reality

[@Luis-qr8ui]

Hey MD, I had the same problem, and to solve it i found several ways, one is that you can move up the outlet from the filter to the waterline so it generates more surface agitation, the other way is by using a hang on the back or something similar to create a waterfall, and finally you can dose oxygen, the same way as Co2 or a söchting oxydator that also doses oxygen. And don't forget about the classic air pump. I personally use the oxydator as it doesn't make noise like an air pump.

[@rimcreaper3500]

Watch out for too much surface agitation, because CO2 will leave water when the surface is moving. That's why you'll see a tank without plants with an air thingy. They need to get rid of CO2 dispersed by the fish by means of surface agitation. I know it's a tank without co2 injection, but plants need CO2 nonetheless. Now the only source of CO2 is the fish and bacteria and the plants use it all ( and need it too apparently!). Beautiful tank by the way! 👍 I wanted to warn you about this, because it happened to me once🙈.

[@shawnburns8190]

I inject air into my outlet at night to break the surface for hours to remedy this. No need for a skimmer during the day. Great channel.

[@raygowers5524]

Consider an air pump in a timer set to come on just before lights out and goes off after the lights come on. Less oxygen in warmer water.

I agree with this comment. A bubble stone is better than a wave maker for discus. This is because these fish usually hate the flow that they create

[@Christian-sr6pd]

Hey MD, don’t forget the more surface agitation = less CO2 in the tank which will affect plants. If anything maybe turn the wave maker at night. Just my 2 cents, cheers!

[@Box550]

Just an idea MD, why not put a spray bar on one of your filter returns. I use one on several of my tanks with skimmers similar to yours and don't have any issues. You get constant water agitation. Great videos, I think the platy tank was brillisnt.

[@havenaquatics3806]

That was a very helpful video! I always had a feeling that no surface agitation would cause some kind of problem like this, but I didn't actually know until now. Another reason for me to reccomend sponge filters or just a bubbler when people try to do a heavily planted tank without a filter.

[@shel.b.1090]

Love that mountain scape with the platys, 👀 ‘s amazing xxxx

[@cocotte9104]

Worth noting about oxygen issues : the beneficial bacteria in the tank also consume oxygen, so even if you don't have plants you should worry about oxygen deficiency in the tank. Some dechlorinators (the ones with Sodium thiosulfate) also consume oxygen so you can have an oxygen drop after a water change. On a similar topic, chloramine removers (not chlorine) will usually produce ammonia, so be careful if you have high chloramine levels in your water.

[@pkoppart]

I think I like the approach of starting with low light and increasing the intensity as needed like MD always does.

[@PaulZyCZ]

I don't have a skimmer (thinking about it on some tanks), but I've been using drip pipe below the waterline. It's not completely hidden (black PVC pipe with drilled holes over black background), but it does it's job and agitates the surface.

[@polarablues64]

Ever consider an air stone that kicks on when the lights go out? That's what I do, I use a smart plug for one of those little aquarium coop air pumps

[@77slate]

If I use an internal filter in a planted tank I use the sprinkler attachment it work well to agitated the surface & breaks the power of the flow so the plants don't get blasted

[@danbyrne3098]

Love the channel 👍 The discus might appreciate the lid being lifted more often, perhaps twice a day, just to refresh the air but retain some humidity. Also, I think your pair of apistogramma in the higher flow tank would probably breed if the slow was flower 👌😉. Lovely tank. Very natural when it's well grown.

[@jonasdamien1762]

You can always use a oxydator of Söchting. In case your elektricity fails at night, you still have a back-up for oxygen. Just for the one tank with the expensive discus.

[@alexsss79]

if anyone doesn't have a skimmer u can simply raise ur outflow up so it's above the water should break the surface nicely

[@charlieewing1810]

I'm surprised you haven't run into Hello Bleher yet. Discus do not come from parts of the world with plants in the water, and to maintain healthy plants usually makes it harder to maintain healthy discus fish.

[@sathmikaliyanagunawardhana9186]

Nope , plants respirate both at day and night and produces CO2. But in the presence of light more O2 is produced by photosynthesis at day. Since there is no light at night, only CO2 is produced.

[@AccessibleCruises]

Thanks for the explanation.

[@UrbanHafner]

Plants are living things and they always use O2. It's just that during the day the break down CO2 via photosynthesis and O2 is a byproduct of it. So during the day they produce more O2 than they use up.

This is something I always worried about on a hot discus tank. During day I run CO2 and during the night I run a weak wavemaker on mine to make sure no gas exchange issues. 👍

[@dnrv4530]

You could just get an air pump and an air stone for cheap or air curtain and that fix the problem and I think it does it more efficiently and don’t make that more flow if the discus get stressed for the flow ( I don’t know anything about them)

[@willit1972]

In my experience discus love a slight flow in the tank. Usually tends to be beneficial for aquariums having a bit for flow with surface agitation

[@professorm4171]

The easy solution is to point the filter outlet up toward the waterline. It'll create ripples.

[@DansReef]

I have the same inlet & outlet as you, but I always have the outlet higher to move the water surface always & the skimmer still skims perfect. Agree the skimmer does not take much to clog up, have to clean mine every week or so 😳
