I upgraded my lights to a pair of 55 watt florecent lights from
ahsupply.com and bam! Everything was covered with algae.

So did I when I upgraded with ahsupply.com.

I traced the algae growth to the use of liquid plant fertilizers
(Nutrifin Plant Gro Iron Enriched .15 - 0 - 0).

Switched to root tabs only, and my algae went away.
