I've recently eradicated a big algae issue in my planted 10g community tank and it has left my water rather green. Try as I might the water stays green. I've gone through about 3 water changes over the last two weeks. (around 40 percent each time) and, while a slightly notable change occurs, the green color is persistent. I can barely see through the water because it is so discolored and it is quite the eyesore. My parameters check out and my fish are doing excellent so I have no worries aside from the nasty colored water.
Any ideas on how to rapidly return the tank water back to a desirable color without having to go through every shade of green imaginable before getting there?
I have neons, cories and ADF's in the tank. Just to rule out anything that could potential harm any of them.
Oh oh, I was wondering if activated carbon would do the trick?
I've also heard of Diatom filters, but I imagine that would be quite expensive.
Also, after doing a little googling I've come to the conclusion that I haven't completely eradicated the algae issue and still have tons of free-floating algae. Thoughts?
