thread for bioload calculation

[shern]

Greetings all, recently i’ve been reading up on some older threads and forums on how bioload of a fish is calculated and with that, all the nuances of filtration. commonly thrown around is the gold fish for example which has a much larger bioload per “inch” due to its habits of eating much more than what you feed and you can see. Is bioload an actual calculation that’s made when regarding specific fish species or is it more dependent on your filtration? For example i run two fx6s for my 250g and though the label on fluval products states its able to take in 400g~, i’m unsure to the limit in which the fx6 can handle. is there any set way to measure and or quantify how much bioload a fish would produce and how much your tank and filters can take before your ammonia becomes uncontrollable?

You are overthinking this. There is no calculation, there are wayyyy to many variables. Stocking levels, size of fish, type of fish, feeding regime, water change schedule and overall volume of water all play a huge part in bio load.

Doing some kind of calculation for just one of those variables is nigh on impossible, let alone a bunch of variables in play simultaneously.

To keep it as simple as possible, in a way that isn't going to make your head explode, if your bio filtration is keeping ammonia levels at a consistent 0ppm you're golden. That's it, headache over!

And as long as you're doing regular water changes to keep the resulting nitrate at sensible levels then all's good, you have a good bio system in place.
