My tank has been getting more and more green over the past couple of weeks and now I can barely see through the water! Little info, 90 gallon with two external filters, heavily planted (all plants growing great), 120 watts of T8 lighting on for 8 hours per day, no sunlight reaches the tank at all, 50% water changes weekly and then liquid ferts added, fish fed once per day.. Not sure if I've missed anything but how do I get rid of this? I have 4 other tanks and they're all crystal clear! There's no algae on any surface, just green water!
Green water driving me crazy!

Weird, usually algae blooms are caused by excess nutrients from over feeding or poor water change schedule. The plants should reduce this and it sounds like you are doing everything right. Maybe the lights are too powerful? Add a UV tk clear it up but that wont help the cause of the problem
I agree a UV will prob be the best way to kill it.

How bout try some "crystal clear"drops, I use them and it helps. It binds with floating algae and drops them to the bottom clearing the water

I had the same problem couldn't shift it with wc's and chemicals , I had to borrow a UV off a mate , ran it for a month or so with lights off problem solved it went completely, I really need to invest in UV of my own not only for blooms but for nasty bacteria
Maybe the ferts are not the correct amount or balance for the plants you are trying to feed. That plus too much light. You also haven't posted the nitrate levels (have you?) and that could be fueling the algae.
