I picked up a Seneye reef and used it tonight to test my PAR levels. Quite surprised how low it was
Probably explains some problems i've been having
I'm going to gradually ramp up over the next few weeks. Out of interest I tried the lights on at full blast, and PAR was nearly 600. THat's including going through a really grubby lexan lid as well. Not too bad for the money.
Anyway how much is everyone else running? I'm struggling to find out how much you should have. Seems like anything from 400 to 800 is recommended for acros. I guess you just keep going till they bleach then back it off a bit.
