Hey guys I have a 250w mh over my 34g cube. I starting to see alot of algae building up. I think my mh pendant is too low because I don't have that issue in my main tank which both is plumbed together. I also just picked up a par meter.
1. So my question is, what is a good par level starting from the top to bottom using a 250w mh over a 20" in height tank. ( bare bottom )?
2. Same question but 400w over 24" in height tank?
