My tank is established pretty well. It's been up and running for about 3 months. I have two large amazons, some micro sword, some dwarf hair and some java moss. Fish are healthy. 4 Harlequin Rasboars, 1 Neon, 3 Guppys, 1 Cory, 1 Male CT Betta.
It's not too heavily planted, more small stuff than big. I'm at about 2 WPG and running a DIY CO2. The problem is that I recently added two large pieces of Malaysian driftwood. Ever since then, I have had a dark tint to the water (tannins) and am now having an issue with white algae on the glass and in the water. My fish don't seem to mine but it bugs me.
I do about a 25% water change every other day. Water test results from last night....before change
Ph--7.0
Amm--0
Nit--0
Nitrate--25 (My eyes fool me on this test)
Temp--78
Frustrating.
Here's a pic of the tank......http
