I had to vote for a 4 of the options even though they weren't COMPLETELY correct...

I run Rowaphos in a reactor (which reminds me, it needs changed..), I use 4 of the Zeo Products but no reactor, I do weekly waterchanges (15%), I use Chemipure Elite (don't think this does much for PO4 tho), and I have never performed a PO4 test.

I've only got a small algae issue in my current tank, and its only on 1 of the piece of liverock, so I've concluded that its still phosphates leaching from that rock.. but really, no idea.

EDIT: I think I can also blame some of my algae to laziness, as whenever I am filling my Top-up pail or buckets for waterchanges, until this week I have simply dropped the RO hose into the bucket and turned it on, not waiting and giving it the chance to flush the old stale water from the unit.

So initial water coming out of the RO usually records 10-15ppm before it flushes clear and reads 0... So I have changed that part of my process and now let it run down the drain until I get 0ppm reading before filling my buckets.
