My tank is still fairly new, been fully up and running for about a month amd a half now. At first I was just checking pH, ammonia, nitrites and nitrates. Those parameters are all close to where they need to be, pH=8.0 (a little low, started adding a ph up additive) ppm, ammonia= <0.02ppm, nitrates=0ppm nitrates=20ppm.
I recently started testing phosphate, carbonate hardness aka alkalinity and calcium. Phosphate= .5ppm, KH= 13dkh, calcium= 420ppm. This is where my concern comes in. Phosphate levels are high, and kh levels are high, but calcium is within range, so should I worry about the kh being just outside range? How do I lower the phospate levels? I've been doing weekly water changes of 20%. This is the 3rd time I've tested these parameters, they have stayed consistent.
My tank is a 60 gallon FOWLR tank, running a marineland 360gph canister filter, a seaclone 100 protein skimmer, and 3 powerheads, flow is 30x, including the return flow from the filter.
current inhabitants are 1 clown, 1 orchid dottyback, 1 emerald crab, 1 sallylightfoot crab, 2 narssarius snails.
