If you are not dosing your tank or top-off water, it may just be a normal cycle and you have to keep tweaking your flow rate. My hang-on-tank skimmer sometimes fills halfway up, but only at night. _________ -- SAW39 45 gal modified hex. Started and cycled August 2005.
Decorated Firefish, 2 Serpent Stars, Ocelaris Clown, Yellow Tang, 2 Green Chromis damsels, Condalactis & Macrodactyla dorensis anemones, 1 big bristleworm.
