I have access to a Par Meter ,, I am wanting to add a couple more acropora a bit lower in my tank ,, what is the Par number I don't want to go below I have a lot of LPS corals in this tank that are doing good ,, for now at least I have found the sweet spot , at least I think I put a small JF Firefox frag onto one of these spots two days ago ,, it broke off of another frag ,, anyway ,, I am breaking the Par Meter out to check my second tank ,, thought I might as well check the spots where I want to add a couple of frags in the bigger tank ,,
