I haven't tested my reef since August of 08'. I used to have my reef water tested on a weekly basis at my favorite LFS, and every time all my parameters would come out perfect. Since Aug 08' I moved from Texas to Manhattan and cannot find a decent fish store around here. There are only Petland Discounts and a Petco.
I have kept my dosing and water changes consistent when that of my water parameters were great. I know its stupid to just assume that parameters are the same as then because I have not changed my dosing routine since then but my corals and clown fish are thriving and even growing.
I do not dose according to the instructions on the supplement bottles. If i did that I know i would be overdoing the calcium big time. I dose the A/B once a week and the Essential Elements bi-weekly. This is the dosing that has worked well in the past, and for what i assume, works now as well.
So, if frozen foods add significant amounts of phosphates to the water, would I be better off feeding with just a quality marine flake food?
