Great video, exactly what I was looking for. My wife bought the 30 litre before xmas and put 3 goldfish in there after 2 days. I never knew anything about fish keeping but when one got sick I took action. I have pretty much all the equipment you advised. The fish are doing fine now, but in your opinion will my tank ever cycle with 3 goldfish? The Amonia is zero and has been for a while, but I cannot get the nitrites to go away. i am using Seachem prime almost daily. I wonder if when I am cleaning the tank (taking the media out and giving it a rinse in the old tank water, and squeezing the sponge out in the same old water) If I am killing off the good bacteria, or if its just the fact that 3 goldfish produce too much waste for the tank size. they are only about 2-3 inches in size, but I am aware they will get bigger. Any thoughts here? thanks

Hi Richard. Are you using a heated tank and is the airstream going though the tank's tube a good flow (i.e. like when you first bought the tank?)? What is pH?
@StepbyStep-biOrb3 жыл бұрын
Also, what is your nitrate ppm prior to doing a water change and are your water tests indicating a rising nitrate level compared to what is in your tap water? How often are you cleaning the ceramic media and is there a lot of fish waste/food present under it each time? Cleaning the sponge filter, how you describe, is fine but don't let it get too messy and if so replace it with a new one. Bacteria are largely associated with the ceramic media rather than the sponge filter (which is there to trap waste). If you are worried about putting in a new sponge though, cut a new one in half, cut the old one in half and replace in the filter using half of each.

@@StepbyStep-biOrb I tend to check amonia and nitrite daily but not nitrate as regular. But there is definitely more nitrite and nitrate in my tank compared to the tap water (which shows very small traces of both). Amonia has always been zero and nitrite is about 0.5 to 1 ppm every morning. I dose 1 ml of prime each day to keep it at bay. Since I first got the tank in December I have only cleaned the media twice by moving it all out into a bucket and rinsing it around in the old tank water. There was quite a lot of fish waste underneath the media both times I did this, I used the syphon and let the filter to rid as much of this as I could (then squeezing the filter out again) before putting the media back in. Could this old waste be my problem? Should I remove the media more often to get all the debris out from underneath? I was worried about killing the bacteria. Sorry for the info overload, any advice would be greatly appreciated as i would love to see 0 amonia and 0 nitrate one day. I’m working through your awesome vids. Thank you

Hi Richard. Thanks for getting back. My initial thoughts, and I'm really, really, sorry to say this (and without knowing a lot more detail from you), but the goldfish you have are probably not best suited to your aquarium size (you've already mentioned they are likely to get bigger. Goldfish, even just one, are best suited to larger aquariums). Putting that aside, it seems like your aquarium hasn't properly cycled and is somehow stuck part the way through. Which, I think, was your original comment. Bacteria associated with conversion of nitrite do take longer to grow and establish and that may help explain the high water nitrite levels you are getting. Sounds like your aquarium has been stuck like that for a while. Your pH is good. But, we need to show increasing nitrates to indicate cycling is happening to some degree. Due to you having a non-heated tank, and combined with having goldfish, it is going to take some time to get any form of reasonable cycling, but you are going to need to keep up with fairly regular water changes. Heating the tank would greatly help the process at this stage, as you could heavily dose your tank with beneficial bacteria (probably worth doing anyway!) using ATM Colony but this product requires a water temp higher than you have to work properly. Possibly look at another similar product? One of my Subscribers has done extremely well with Pets at Home 'Love Fish Filter Boost Beneficial Aquarium Bacteria'. This might work, but it depends on the temp requirements of that product (I don't know!). Also, do you know anybody with an established aquarium that could let you have some of their media or filter sponge? If so, get as much as you can and add to your tank! Normally beneficial bacteria need 24-25 degrees C to build in number and work well. Temps below 18 degrees reduce bacteria growth by about half! My gut feeling is that your fish are producing more waste than the bacteria can grow to support it. Yes, Prime will help to reduce toxicity for the time being, and if you use the much more elevated levels they indicate on their website. But that isn't really solving the basic problem and is providing a much needed but short term fix. Regular water changes (1/3rd), every couple of days, may help too and is the way I would go. I'd certainly suggest not feeding the fish for 3-4 days to reduce the nutrient input and to allow the bacteria associated with nitrite conversion to build up. Feed the fish again very lightly for a few days, and then don't feed for another several days! Ignore the demands of fish for feed. However, once you get passed this stage and into cycling there will be a point where your fish will continue to grow and will very likely to need to be re-homed. Please keep in touch as I will help as much as I can.

BTW, yes API Master Test kit I would say is an essential especially with a new aquarium. Once things settle down the strips are then good for doing the weekly checks (much quicker) and are indicative of anything not going right. You can revert to then double checking if anything is not right with the API Kit. Once beyond cycling and settling in the tank the best strips for regular checks (weekly) would be the 6 in 1 Tetra strips.

This one should help in terms of set up: studio.kzbin.infoLy_HgUvlfAk/edit. Also, read the Description that accompanies this video as that also provides information (click on Show More just below the video) For ceramic media (and also biOrb Pearl Media) the only thing you need to do is to soak and rinse the media, mainly to remove dust. You need to remove as much dust as possible, to avoid the dust reducing the clarity of your aquarium's water. . The amount of dust you get in a bag of biOrb media is highly variable. It may need a few rinses to properly clean it. My suggestion is not to rinse ceramic media under tap water, as described by biOrb. I prefer to use buckets of water containing dechlorinator (e.g. AquaSafe). BTW It wasn't a silly question... It's a good one! :) Best, Mark

@StepbyStep-biOrb3 жыл бұрын
Hi Scott. Yes, (unfortunately) they certainly need cleaning out as they are all self-contained (no water flows going in and out and then being cleaned through a separate system). I've just released a video about Water Changes which will probably give you some insight, so have a look at that. The mechanical filter (sponge part) needs cleaning or replacing roughly every month. That frequency (and whether it just needs cleaning-out or replacing) also depends on how many and what type of fish you have. Some fish produce high levels of waste (e.g. goldfish) and they would not be high on my list of choice (they also need much bigger tanks!). Changing the filter though is really easy, 10-15 minutes and then you're done! If you are going to get an aquarium (biOrb or not) and want to keep a number of fish I would suggest a 30 litre tank or larger. I would probably go as far as saying that all aquariums of this sort of size will need regular cleaning and maintenance. Hope that helps. Nice to hear from you, and thanks for watching. Best, Mark

Well, it's straight forward really. As a general starting point, the general rule for the number of fish for an aquarium is 1" per US gallon (or 1" per 3.5 litres). A one inch fish is the fishes body length - excluding the tail. Fish choice will depend on whether the aquarium will be heated or not (heated tanks offer more options for a larger number of fish species choice and are much easier support "aquarium cycling". See my video about adding your first fish. For the the initial stages, with a beginner and also a new tank, I suggest going for fish described as being "hardy" - If you search "hardy aquarium fish" on the internet you should find them easily (such as guppies, endler's, danios). A really good thing (and will make your life far easier) is to match your fish choice with your water supply pH (tap water). If you currently don't have the means to test tap water pH go to your suppliers website and find their 'water quality' page. This should tell you the average tap water pH levels. When you establish the pH level let me know what that is and I can advise regarding the best fish (or fish combination) for you to consider. Also, let me know what aquarium size you have or are planning to get. Hope that helps for now. Best, Mark

@StepbyStep-biOrb3 жыл бұрын
That's a good pH and covers the tolerance range of most tropical species. pH 7 is considered the perfect level for a mixed aquarium but yours is almost at that so isn't worth messing around with. . So, typically danios, barbs, minnows, tetras (although some can be sensitive to cycling) betta, dwarf gourami, rasboras would all be fine (just need to get the correct mix that get along if you want to have mixed species). If you want to include either a betta or a gourami (don't get one of each!) drop me a line as you would need to get one that has the right temperament to be in a mixed fish aquarium. Watch my video about adding your first fish - I always recommend using ATM Colony (Freshwater) for cycling an aquarium as I have never lost any fish or had an issue using this product. Colony also allows you to fully stock the tank with fish on day one (it needs a heated tank and pH above 7.2. All you need is a dechlorinator (e.g aquasafe) for your tap water treatment and a small bottle of Colony (for a 60L) or the next bottle size up for a 105. My preference, with a new tank, is to set it up, add treated tap water and let it run with the air pump and heater on for several days or more, before adding Colony and your fish. Hope that helps.

@StepbyStep-biOrb2 жыл бұрын
Hi again Fiona. Good news that you are going to get your biOrb re-going. Yes, using empty 5litre water bottles is a really great way to do water changes etc for a biOrb. Ideally you should use your tap water for the aquarium and you will need to establish what the pH of your tap water is (especially if you have moved away from where you previously lived). You would be better off choosing fish to suit your tap pH rather than making adjustments to your tanks pH level. Let me know what the tap pH is. In terms of tetras (I assume you mean neons) they prefer softer water of about 6-7ph but if you do have 7.5 that should be fine. Neons are sensitive to poor water conditions (i.e. nitrate levels) and are even more sensitive to variations in water quality. As a result , they are a species best added after the tank is fully settled down - say after 6-months (although some people get away with adding them too early). Generally they do better added to a settled tank and will then have a longer life expectancy. Cardinal tetras are similar. I agree that the filter system in a biOrb is not that great at drawing in and then collecting waste. See my video on aquarium vacs as these are the best tool to control biOrb waste. Yes, fish-less cycle is a good way to prepare the tank - I assume you know how to do this from previous experience. Adding ammonia is probably the best way to cycle this way. Fish-less cycle can take many weeks and sometimes months to complete. But, as you say, it can sometimes be achieved in a shorter time. Adding bacteria to the tank, and especially adding some substrate from an existing aquarium (if you know someone that has one) will help to grow the bacterial colony much faster. I have four biOrbs and so have various fish species across these tanks - but generally I have dwarf gourami, zebra danios, pygmy cory, and the following Brazilian tetra species: flame, x-ray, black phantom and lemon. Best, Mark

If you want to go down the tetra route, and for an early addition to a newly set-up aquarium (rather than neon, cardinal), I suggest that you have a really good look for "hardier" tetras! The following would be really perfect for you: black phantom (brilliant!), Flame, x-ray and Lemon. All of those species, or a combination of them, are stunning fish to have!
