I do not have a phosphate kit. I have chaeto in my refugium though that grows pretty well and is a nice dark gree.
I have a ro/di system and that is all that goes into my tank.
I do about a 30% water change once a month.
I siphon my tank only when I do water changes, both off the rocks and sand.
I have been feeding mysis shrimp along with flake food once a day. I do a little at a time and do it over a 5 minute period.
Occupants: 3 damsels, 1 oscalerus clown, 1 flame angel, 1 black sailfin blenny, 1 diamondback goby,1 royal gramma, 10 turbo snails, 5 hermit crabs, 1 starfish, 2 peppermint shrimp and some sort of little crab I have no idea where he came from.
Would it help to have more cleaners? What is the rule of thumb with cleaners and the size of tank?
Thanks
