Thought I’d post some advice given to me on phosphate dosing by someone who runs a small coral farm.
he said that he tests weekly for phosphate and yes sometimes his system runs to 0.00 bc of coral load. He will dose neophos at the appropriate dose to the level he wants, he will increase feed a bit throughout week, notate these changes in habit, and then test again in a week. He keeps this cadence to basically give him a workable and progressive schedule to getting where he wants.
now my system is about 1000 times smaller so waiting a week between tests was not working for me when phosphate was at 0.00, so I would test every other day while dosing until I got a reading and I would then try to maintain through elevated feeding of reef roids at night. I then test once a week when I am reading some phosphate (and you should do this because I find that sometimes with my feeding habit and filtration and coral growth I run to 0.00 now and then). This method has worked very well for me.
Also my tank is 1.5yrs old and I do use mostly Marco rock but I think all live rock will absorb phosphate, I think even sand beds will too, but @Randy Holmes-Farley would know much better than me.
Hope it helps and keep at it, it will work!
