I have (2) 40 watt flora glo lights and (2) power glo lights. It is a 75 gallon tank. Ammonia and nitrite test zero usually (I really haven't tested those in a while) and NitrAte tests 5-10 lately. (I'm using the drops test kit). I'm running a Marineland c 360 canister filter.

I put Flourish Tabs in a few months ago, they're probably ready to be replaced. I put in a capful of Excel once a week usually.

The algae is like thick, soft, fluffy and stringy - like dark soft hair or something. I'm color blind... it's either dark green or brown. It's not new, and it didn't just show up one week, it's been consistent for a while. The snails/pleco eat it off of some of the plants, but there are other small leaved plants that they just can't get to, and those look unappealing.

So... so far we're thinking that I need to put in *more* ferts for the plants? Is that correct? Thanks for your help all.
