What is the ammonia and nitrite readings? It could be fouling on the LR
I just tested the water and here's what I found:
Ammonia = .12
Nitrite = .05
ph = 8.5
DISCLAIMER= that's only the second time I've used my test kit. So I expect some margin of error. I plan on bringing a sample to my LFS
tomorrow to have them re-test it.
Is the rock new?
Ummm, I put it in my tank exactly 3 weeks ago today. I got it from the LFS
and brought it right home. I have no idea how long the store had it before I took it.
No, I cannot see through it and there do not appear to be any "veins". It's very hard - I cannot scrape it with my fingernail. It looks kind of like white mold that you would find if you left a can of tomato sauce for 6 months in your fridge. Sorry but that's the best way I can describe it.
