I recently switched to reef salt. my dt is 60 gallon and sump is 40 gallons. there is approximately 70 to 80 gallons of water volume. I don't have any live rock just a lot of siporax in the sump. my bio load is very low. a few frags of sps, and lps and 10 small fish. my nitrates are barely detectable however, I have been battling phosphates. I am using a lot of gfo atm to help keep no4 at reasonable levels. I have not started using np pro or pro bios yet. I am battling no4 hard at the moment and think the use of pro bio s and np pro might help with my no4 problem. my concern for using them is that they will bring my nitrates to low. any advise appreciated.
