Bioblocks and bottomed out nutrients

[GiannisDim]

If your tank is 2 months old, its expected youll have dinos. The anaerobic bacteria are primarily in the sandbed, if im not mistaken, which is very young in your case.

If you used dry rock and sand, the odds of having dinos seems to be far more likely. I definitely dont think bioblocks are the solution...im sure many people wish they had have thought of creating little square blocks and marketing them as a habitat for bacteria...I'm skeptical the claims are very accurate representations...

Is there any way from too much media in 20g tank to have 0 po4 and 0 no3, because the blocks is for 700g tank as they say in the box of the blocks

I doubt it...how do they define removal rate in order to define how many blocks are needed for a tank of X volume? And what does the company use to determine that the blocks reduce nutrients to whatever level they set as the removal rate? Both questions seem like they would involve too many variables to even provide a reasonably accurate answer.

For example, Id imagine they tested the blocks in an aquarium of an undetermined volume (hopefully), but if your tank differs in bacteria count, feeding, bioload, etc., then the removal rate from their test will differ from yours or anyone's.
