Lost all 11 fish to ich a month back. After watching 5 die from suffocation I put the rest out of their misery when they showed signs of suffering. An unpleasant experience, but from which I learned a lot.
may be nice and knowledgeable but they are primarily there to sell fish; thus they have little interest in your fish surviving for long periods.
Tank is fallow since (except two survivors, a bluefoot hermit and a starfish) and I don't plan on introducing anything until well after Easter (that'll be about 7 weeks).
Last Saturday I removed and boiled the sand, did 100% water change and added 20Kg of live rock (40Kg now in total). Result looks like this (tank is 3 months old):
6 days later I'm seeing this brown algae growing again:
I'm not feeding or putting anything in the tank. The chemistry is all at 0.0, 1.021, 25Â°C, PH 8.1. 480L, wet-dry sump, 600L/hour Eheim mechanical filter, 1100l/hour powerhead behind the ceramic decor, 2X50W 15000K lights.
Something tells me that I need to get rid of this stuff before even considering adding any livestock. Is there a kind soul who could give me some guidance please?
Thanks in advance
