My other water parameters are fine: ammonia - 0; nitrite - o; nitrate - 0; Ca
- 370 and coming up slowly with cc
But phosphates remain at .1 to .25 -- it is hard to read the Salifert scale. I have plenty of green macroalgae growing, and harvest it weekly. I only feed the maroon clown and flame angel what they gobble up in a minute or two, and have shrimp, crabs, snails, a starfish and an urchin to clean up.
I have two hob
filters running with lots of carbon, and clean the filters a couple of times a week. Aqua C Remora skimmer is working well.
How can I get phosphates to zero?
