How long to expect drop in chemistry levels?
I just got my phosphate test kit, and phospure (iron-based phosphate remover, I've read aluminum isn't recommended, and the added iron should help the beneficial algae growth) in today, placed two tablespoons (about the directed amount) of phospure in the bag I placed in the refugium, I added carbon about a week ago to the refugium, and 2 days ago I added 2 shaving brush algae to the main tank, and some chaetomorpha to the refugium.
Currently my nitrates are 30, nitrites 0, ammonia 0, phosphates 0.5, and I've been fighting a losing battle against red cyano for months, even after cutting the feedings to a 1/2 cube of frozen food per day, and 1oz of phytoplankton per week for the corals
How long does it usually take for all these additions to take effect? (I think the carbon and algae would get rid of nitrates, maybe ammonia, and phospure for the phosphates, of course)
