I have a 40 gallon FOWLR
tank (tank is one month old - live rock is three weeks in the tank, bought it wet). I have gradually added fish, 5 total. 2 clowns, 1 damsel, 1 blue tang (added yesterday - very small one...yeah I know it will grow), and 1 royal gramma. Also 5 hermit crabs, one cleaner shrimp and one crab (large red claw). So after having the water tested at the LFS
the water is good, however, the owner says the tank is almost though a cycle and is almost done?/! OK.
After having 150- watts of light (new Jebo light) above the tank for 3 days now, I now have brown algae on half of my live rock and some substrate (crushed coral). Now What?????
Do I do a partial water change? Do I buy 5 more hermit crabs to assist the other 5 who are doing their best? Do I do nothing? I have already cut the lights from 12 hours to 6 hours a day beginning today.
Any ideas? I am also adding a drop every two days to the tank of Phyto Max the past 8 days. Could this be a cause? Could too much fish food be a cause? I use one cube of frozen brine shrimp a day - half in AM and half in PM.
ALso I have a the stock JEBO trickle powerhead filter on the back/top of tank and an Eheim filter. Should I remove the medium from either filter system?
