Thanks for the replies. Currently I am running two powerheads on the top of the water, my cleaning crew is still quite small and is based up of 5 hermit crabs, and the lights that I am using are from the manufactures hood that came with the setup (marineland 29 gallon deluxe combo). My water readings are as follows: Ammonia - 0, Nitrite - 0, Nitrate - 5, PH - 8.2, salinity - 1.021. The red algae originally was on one rock on saturday, now it is all over most of the rocks, on the substrate, and approaching the glass walls. At the rate that it is gorwing it would pretty much consume the tank by sunday or monday (estimate). I do not have a phosphate test kit, but am really considering buying one. My next water change is due this weekeend, should I just do it now or wait and syphon it out this weekend? Thanks A lot
