What lights are on? I started my system with tapwater, and ran real bright T5 aquablues almost from the getgo, and never had green algae. Didn't run phosban/rowaphos or nothing, then too, and my first week of water changes was with tapwater. I had diatoms for about a week, then hair algae for about 3 weeks, though...
I think I remember reading that waterborn algae is caused by too little light?
maybe those nitrate sponge resins leech chemicals back if they're full? if it's a new tank, liverock cycling could fill them up quickly, causing a belated algae bloom once they leech back?
