nabokovfan87 Posted December 2, 2022 Share Posted December 2, 2022 Let's call it a fun exercise. Assuming all the fish grow out in your tank, is the tank overstocked? I'll plug mine into AQAdvisor and try to see as an example. Feel free to play along. Note: yep, I totally wish they had updated filter numbers, go by GPH if your filter isn't there.https://aqadvisor.com/ Quote Your aquarium filtration capacity for above selected species is 254%. Recommended water change schedule: 67% per week. (You might want to split this water change schedule to two separate 42% per week)Your aquarium stocking level is 182%. Sounds about right and right on par with how much water I change weekly. The tank is definitely fine and it's doing well. I absolutely wish it was bigger, but I definitely over filter and over maintenance things to keep it clean. Let's check my other tank: Quote Your aquarium filtration capacity for above selected species is 167%. Recommended water change schedule: 33% per week.Your aquarium stocking level is 106% .... Once the fry are in the tank and fully grown it's going to be time for the 75G. Quote Your aquarium filtration capacity for above selected species is 86%.

Doesn't calculate plants or what you do to keep the tanks happy! It also ignores how much you feed! 1 Link to comment Share on other sites More sharing options...

JJenna Posted December 2, 2022 Share Posted December 2, 2022 Right now I'm understocked, but in all actuality may be overstocked when I add all the various fish I want haha.

CorydorasEthan Posted December 2, 2022 Share Posted December 2, 2022 I remember playing around with this website all the time before I got an aquarium lol. I'm surprised that it says I am understocked, in the past mine's always been overstocked (I guess moving the guppies to a different tank helped!). 1 Link to comment Share on other sites More sharing options...

RockMongler Posted December 2, 2022 Share Posted December 2, 2022 Mine is understocked, until I try to quantify the number of Malaysian Trumpet Snails I have. Then it goes bonkers. It also has no way to quantify plants in the tank, which play a huge part in water quality and controlling nitrogenous waste and so by extension, how often you need to change water. I also have a hell of a time trying to figure out the filtration capacity of my attempt at a stream flow manifold (I have two intakes, each covered with a large co-op sponge filter intake) that is powered by a powerhead. I usually change my water not because the nitrates get bad, I change it because I have hard water (I want to prevent a buildup of too much hardness), and to use the gravel vac to get rid of all the extra detritus that builds up along the front in my gravel.

Jungle Fan Posted December 2, 2022 Share Posted December 2, 2022 Aqadvisor is sort of like tell me how tall you are, how much you weigh, the size of your family including extended family, your budget and I'll tell you what vehicle you need to drive. You're always going to end up with a refurbished surplus yellow school bus. No accounting for invertebrates, water change frequency, water quality, plant mass, substrate biomass filtration, and mechanical/bio filtration via the filter, be it HOB, Sponge, Canister, undergravel, etc. ... Overstocked, and understocked, are some of the most abused terms in this hobby. Bottom line, if your water perimeters are fine, your fish seem happy and aren't sick, your tank doesn't look crowded with fish like a Pink Floyd concert with fans, or is overrun by unintended algae, and your plants are healthy and doing fine you are doing something right here. Any app that tells you how many fish to have is sort of like the games kids play to figure out how old they'll get, who they'll marry by name, where they'll live,... a diversion at best. 2 Link to comment Share on other sites More sharing options...
Schuyler Posted December 2, 2022 Share Posted December 2, 2022 Do you think it's safe to add more fish? Fluval 407 is probably way overkill for a 40b but it's also running at like 30% 2 1 Link to comment Share on other sites More sharing options...

Put a large pre filter sponge on anhob and you have slowed gph a bit but significantly increased surface area…. various ceramic media types are advertised as having tremendous surface area but there is serious question as to whether pore size is sufficient to allow bacteria to colonize the pores… 100% On 12/2/2022 at 8:07 AM, Doc_Ho11iday said: What filter would you choose if you used the large Aquarium Co Op sponge filter?

I will say that aqadvisor is a really useful and fun tool for beginners. When I was first starting in the hobby, it helped me plan things out, and get a basic handle on tank size, bioload, filtration capacity, sex ratios, temp or pH conflicts, species traits, and so forth. I give full credit to the creator(s?) for making something that is pretty good at what it does. But as with everything, if you don't have some understanding of the assumptions (ie things that need to be true for the output to be valid), it can lead you astray, to greater or lesser degrees. 1 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted December 2, 2022 Author Share Posted December 2, 2022 100%. I really, really enjoy it as a tool and I have no issues giggling and recommending it as an actually useful thing. Amongst other information, what I like is: -Tank size vs. fish size checks -fish parameters are compared for compatibility -changing X % of water is actually really helpful if you have no idea where to start (often you can change more) -it forces you to consider that fish grow and they won't always be smaller sizes. Things like verifying aggression issues is also important. 2 Link to comment Share on other sites More sharing options...

I think that's potentially a value of the no plants assumption. Worst case, this tool is taking things from ammonia ---> nitrate, not taking that nitrate and doing anything with it. Heavy nitrates = high demand plants, right? 😂 1 Link to comment Share on other sites More sharing options...
Nik_n Posted December 2, 2022 Share Posted December 2, 2022 As already mentioned above, it doesn't account for plants. Plants filter the water and use the nitrates to grow, so the more plants you have, more filtration in your tank. However planted tank only works if the balance has been archived, meaning the waste produced by the fish is absorbed and used up by plants in order to grow. Many new aquarists struggle with achieving the balance, which means they need a filter in order to keep water perimeters whit-in acceptable levels. Hence the website would be used for new aquarists and I thinks that it's intended purpose Link to comment Share on other sites More sharing options...

PineSong Posted December 3, 2022 Share Posted December 3, 2022 (edited) I'm afraid if I enter the numbers for my 20g tall, the program will implode. That tank is on a "no new fish in, no fish out" rule due to a possible mystery illness and as crazy as it seems, I feel better not knowing just how overstocked I am. 😞 I did run my 20g long through the calculator. It's hard to guesstimate my numbers without netting out individual fish because most of them look alike. But ((hangs head with shame)) this tank has approx 50 fish in it: 25-ish endlers; 5 adult platies, 3 juveniles; 1 molly; 1 guppy; 10 neons which may be "jumbo" neons; 5 green neons; unknown population of yellow shrimp. The calculator says I'm at 138% capacity and should be doing 70% water changes per week or 2x 45% changes. I am relying on plants to do some heavy lifting here, and maybe that's not fair. I am not sure how a 70% or even 50% water change each week would impact shrimp. I can definitely do more water changes than I am--but should I? Per test strips, this tank hardly ever needs any water changed; I have to add root tabs 1-2x month and Easy Green 2x week to keep any nitrates at all in it for plant growth.

Caradina or are they Neo's? My amanos (and corydoras) could literally be fine with 100% water changes if it was possible. The biggest thing is making sure tap and tank are even. Most shrimp like highly oxygenated water and so that's beneficial when you change out water. Link to comment Share on other sites More sharing options...
DaniV Posted December 3, 2022 Share Posted December 3, 2022 Assuming I've plugged everything in correctly, I'm understocked...makes sense since the tank is a month old. Give it another month and that'll change. 😛 1 1 Link to comment Share on other sites More sharing options...
