Calculate the average protein content of the food added.So ive measured my daily food intake with just dry food. Its approximately 4.1 grams a day.
The C:N ratio of the feed used will influence the nitrate production and the possible daily nitrogen overproduction.
A basic rule for determining the C:N ratio and nitrogen content of feed:
The C: N ratio of a feed is generally calculated as follows: regardless of the protein content, the carbon content of a feed is always considered to be 50%. To get the C: N ratio, one has to find the N%. This is done by dividing the protein by 6.25. For a shrimp feed with a crude protein of 21%, the N content is 21 divided by 6.25 = 3.36%. The C: N ratio of the food supply is 50 divided by 3.36 = 14.88: 1 or nearly 15: 1 .(PohYongThong2014) ref: https://www.baharini.eu/baharini/doku.php?id=nl:makazi:het_water:filtratie:biofloc#voedsel
A basic rule for using a BADESS: use 1% +1% media in a 120% reactor and one will be safe for 95% of mixed reef aquaria in operation. If needed, one may always add some media or use a second reactor.
If you target 0 nitrate in the effluent and try to remove 150ppm in one passage, you need at least 2% +2% media.
