Well, I finally got around to figuring out how to read that stupid KZ Kalium test kit. (btw GRRRR) So I am now confident that my potassium is 380 ppm +/- 10 ppm. I'm interested to see the results of maintaining potassium. I have heard great things, and my expectations are substantial (I loathe disappointment).

Hey Tony! I don't have a cover on the tank. The lights cover most of the open area, but it's still an open top. My tank is mainly occupied by fish known to be jumpers though.

I hope to have my canopy built in January (but I'm a procrastinator).
Thanks Chris! Those blue Rics are farly fast growers too. They have sweet neon green mouths.
