Tank parameters -
Unfortunately, I can't answer that question....as I haven't invested in a test kit yet.
I will be after the holiday...unless I receive one..
I want something not too complicated, or costly.
I usually take in water to a LFS and have them test it.
Everytime,..it's good..I can tell you that.
The tanks' been up & running since August.
Bio load is light, I'd say.
I brushed it off the rock last night, with a toothbrush..it was very easy to remove.
Also noticed the stuff in my Fuge' seems to be gone...for the most part
I also moved that rock into more direct flow-line from my powerhead.
