hi, i base my wc and vacuum routine on how many fish i have . Since the total loss . there are not nearly as many fish as before ...the tanks are very understocked atm, so i lessened the wc's and vacuuming . As I build up to more fish ,when my water permits, and especially with plecs , i will be doing more. In past , yes i did do 10%daily wc's to keep the ph level at 6.8(with the help of crushed coral). So am i doing too few wc's an vacuums, does it matter how many fish are in the tank to determine how often wc's and vacuuming is necessary ? and ususally clean the filter every 2 months in past, staggering the cleanings . Am i doing this wrong? Havent yet cleaned the filters yet since i restated the tank,but plan to do one this weekend and the other one the following.
