Keeping parameters in check
in a 47g mantis shrimp tank - what is the primary biological filter? I ask since I only have about 3kg (Maybe 7 pounds) of LR, and a DSB made from aragonite. I have a very small Tunze 9002 skimmer which skims almost nothing.
My nitrites is 0,2mg/L, and nitrates is 20mg/L. pH is 8.2, temp 26.4 and sg is 1.0266. Alk is also low at 4dKH.
What can I do that I can stick to monthly 20% water changes, and still have my nitrites and nitrates in check? I feed the mantis shrimp a small piece of mussel/clam/scallop/fish once a day.
