| Re: Ricks' Oceanic 14G Biocube - my first salt water tank I did a big 50-60% water change after stage 1 of my cycle before adding the CUC. Been doing weekly 2-3 gallon changes since and have kept my levels pretty steady (so far) never got the N03 to 0 yet, but its lowish 12.5. Considering trying purigen or some other product to try to absorb the nitrates. Not ready to fuge my back chamber yet which I hear is also helpful. |
