Krillan1r Posted June 9, 2021 Share Posted June 9, 2021 (edited) I have 3 adult angelfish, 4 juvenile angelfish, 5 green corydoras, 2 otocinclus, 2 rubber lip, 4 blue gourami. They all live in a 75 gallon aquarium. Edited June 9, 2021 by Krillan1r Link to comment Share on other sites More sharing options...
Daniel Posted June 9, 2021 Share Posted June 9, 2021 There is no exact formula, but what you have sounds fine to me. Do you have any plants? Do you have a photo? Link to comment Share on other sites More sharing options...
lefty o Posted June 9, 2021 Share Posted June 9, 2021 sounds okay, as long as water conditions stay good, no problems. Link to comment Share on other sites More sharing options...
tonyjuliano Posted June 9, 2021 Share Posted June 9, 2021 There really isn’t such a thing as “overstocked”, just “under-maintained”. If you can maintain water quality (this means zero ammonia, zero nitrates and a reasonable level of nitrates), then it doesn’t matter how much livestock you have. The “challenge” is to design a system that supports what you want, with the effort in maintenance that you are willing to devote. You could possibly have 3x the amount of fish you already have. But that may mean you’re going to have to do a lot of water changes to maintain safe parameters, or design a system that incorporates a high level of super efficient bio-filtration that can reliably maintain the waste load. High fish count & low maintenance is the “nirvana” of this hobby. 3 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted June 10, 2021 Share Posted June 10, 2021 Sounds perfect to me, why do you ask? Are you wondering how many more fish you can add? 😀 (Like most of us) Or are you having trouble keeping water clean? Link to comment Share on other sites More sharing options...
Guppysnail Posted June 10, 2021 Share Posted June 10, 2021 Agree. My tanks all have personal space not overstocked spacewise but my bioload is ridiculously “overstocked” for the tank sizes as I am physically incapable of larger tank maintenance so upsizing is not an option. I do daily maintenance on each depending on their needs. My hubby calls it poop patrol. I have pristine water perfect test readings I test daily. I am retired and can devote this time. If I start missing though I will lose fish. So enjoy your fish do maintenance as needed but don’t stock beyond your time limitations and you will be fine. At least this is what has always worked for me. 2 Link to comment Share on other sites More sharing options...

Daniel Posted June 10, 2021 Share Posted June 10, 2021 One of the easiest ways to deal with nitrates is plants. Substrate too will not only provide an anchor for more plants, but it will also create more surface area for beneficial bacteria to live on. 2 Link to comment Share on other sites More sharing options...
NanoNano Posted June 10, 2021 Share Posted June 10, 2021 Building on the point made by @Daniel - you also want to be trimming and removing portions of your plants regularly to encourage on going new growth. I like plants like Amazon Sword, Cryptocoryne Retrospiralis, and broad leaf floaters for Nitrate control as all three grow extremely fast which A) Removes Nitrates B) Gives a quick recovery time if you happen to have an overzealous or attention wandering trimming session which ends up in a "bad haircut"...which happens. 1 Link to comment Share on other sites More sharing options...
NanoNano Posted June 10, 2021 Share Posted June 10, 2021 One of the other things to consider is your "custodial staff". Right sized populations of snails (both burrowing and surface feeders), shrimp, and other bottom feeders can contribulte enormously to both the effective waste breakdown and the health of the bacterial biome in a tank. 1 Link to comment Share on other sites More sharing options...

Brandy Posted June 10, 2021 Share Posted June 10, 2021 Good catch @Guppysnail. @Krillan1r, your tank is bare bottom and looks new-ish. How long has it been set up? Link to comment Share on other sites More sharing options...
Guppysnail Posted June 10, 2021 Share Posted June 10, 2021 No worries @Krillan1r we have all been here at one point for one reason or another. I don’t want to assume anything about your knowledge level. You do have a bacterial bloom. This is not your beneficial Bacteria it is heterotrophic. While not directly harmful to your fish it greatly depletes oxygen and stresses your fish. Go old school fish in to finish your cycle it used to be the standard done right every one will be fine. Add 2-3 extra air stones or at least one it will distress your fish. Keep your nitrite at .25. Do not drop it lower you need some to cycle. Don’t let it go above .5. It takes 4 weeks for the bacteria to grow that converts nitrite to nitrate there is no speeding it up. Bottle stuff does not work read up on studies done by actual scientists. Be patient and consistent. Like I said back in the day....yup I’m old and love it...there was no other option. Please ask if I can help. If I have overstepped I’m so sorry. I love to see folks succeed in the most rewarding hobby. I’m sure there are thousands who disagree or have other opinions but I’m old and this always worked for me and my exotics vet agrees.

Guppysnail Posted June 10, 2021 Share Posted June 10, 2021 Thinking about this I want to add. Bare bottom is just fine no worries. But for the stocking level you have you simply may not have enough surface for BB to grow. Put something in there a big rock a big plastic plant dollar store pot scrubbers weighted down ugly but effective more plants anything just more surface area perhaps.

Folks will recommend different solutions based on that. In any case adding an Aquarium Coop sponge filter will help a lot and it’s only $10! https://www.aquariumcoop.com/collections/sponge-filters/products/aquarium-co-op-coarse-sponge-filter?variant=29459428507717 1 Link to comment Share on other sites More sharing options...

Krillan1r Posted June 10, 2021 Author Share Posted June 10, 2021 It's about a month new had started with goldfish for 2 weeks then started adding fish its a 75 gallon I was thinking may be filter I'm using tidal 75 should upgrade to tidal 110 because it can filter more than 75 plus fishes Link to comment Share on other sites More sharing options...
Guppysnail Posted June 10, 2021 Share Posted June 10, 2021 (edited) Filters provide surface area and oxygen bigger isn’t better. Stuff the compartment with coarse sponge and you will get more bioload filtration capacity (gallon ratings mean little)than upgrading to a bigger one stick a coarse sponge prefilter on the intake and it will supercharge your filter. Aq coop has a video that’s rather good describing how to upgrade your current filter for $10 or less Edited June 10, 2021 by Guppysnail Link to comment Share on other sites More sharing options...

Yeah I’ve never tried to run a tank on just sponges but after that video I’m giving it a try. My stock likes fast current in most of my tanks but the new one is just male guppy fry and snails galore so I went for it so far a medium and nano I had are preforming terrific Link to comment Share on other sites More sharing options...

Just to clarify, heterotrophic bacteria is what is responsible for the production of ammonia. They mineralize the organic waste (break down the uneaten food, fish waste, dead plant matter, etc. into ammonia). In a newly setup aquarium, the heterotrophs get to work quicker than the "beneficial bacteria", causing the cycling bloom you are experiencing. This is the initial stage of establishing the cycle. What needs to happen next is for the nitrosomonas bacteria to begin multiplying, they will consume the ammonia and convert it to nitrite. From there, nitrobacter bacteria will colonize and turn the nitrite into much less toxic nitrate. Edited June 11, 2021 by tonyjuliano Link to comment Share on other sites More sharing options...
