Bio-Filter Calculations

I'm just playing with you too.

The calculations depend on the type of filter and the amount of food you plan to feed. Some filters, like static submerged media, can't be computed because they vary too much, the bio conversion goes down as the media is covered by sediment.

Te easiest method is to estimate just based on similar ponds, fish load, feeding, climate. And then track ammonia to see if the filter is enough. This monitoring of ammonia, nitrite, nitrate has to done in any case.

Absolutely unhelpful for the homeowner; if you don’t have a “rule of thumb” formula, then just say so. Or better yet, don’t say anything.
