I have another kind of algae, and not really sure what it is. I have plants in both my 10G tanks, and both were doing great til I started dosing Excel in one of them. Now I'm getting this algae on my ground cover plants. Don't have pics right now, but the best way I can describe it is it looks like rust build-up. I'm also getting it on the output of my internal filter. Any ideas what it might be? The tank that I haven't dosed Excel doesn't have it. And it didn't start until almost a week after I started dosing Excel in the one tank, and have 2 25W screw-in CF
bulbs over the tank. I started dosing the Excel a week after upping the 2 10W bulbs to the 25W bulbs that I had taken out before because they were too big for the other hood. But they seem to fit ok in this hood. So there it is. The algae in question looks like rust buildup. No threads or slime. Just looks like rust buildup, and haven't checked the feel of it.
Got some pics.......
Also, there's very little plants in this tank, just a couple patches of this ground cover, and a little bit of one that looks like grass. It's even got the rusty stuff starting on it.
