Thanks!! I have worked really hard to get my tank like this for the last couple months.....I appreciate it.
The suggestion for the chemipure was from nanonewbie and it was a good one....
I prolly will not upgrade my lighting on this tank. I will eventually go 150+ gallons in the next couple of years and then this will be my refugium. I would like to have 4 watts per gallon on my next tank. I have a friend who is running 3 watts of light in his 100 with T-5 HO and has a clam that is thriving....so who knows?
