| Re: Low alk and PH input needed Eventhough I top off with kalkwasser, I occassionally have to adjust my alk. The frequency and amount of alk needed varies but I usually only need to buffer it once every few months. The cleaner I keep everything (sponges, socks, ditritus, skimming, etc) the less I have to buffer it. Also, if you have a high calcium load (sps, clams, etc) then the alk may need adjusting more often. |
