The alkalinity is somewere around 6 to 8 dKH
. The test kit I have is a Kent Im thinking about replacing it with something more acurate.
The greenish brown rocks (absent the coraline) arent not slimy its just green and brown algee. It looks like the same stuff the rocks have when thay are new to the tank defor coraline takes over.
As for the lighting I just replaced all 4 bulbs about 3 months ago.
Do you recomend that I try geting a uchen, or would it just eat the reamaining algee.
