Hey guys! My new tank is coming next week its a Reefcasa Flat 9 and I plan on starting it up next week! As such I do not have a par meter. I'm hoping my LFS has one I can rent. but for right now I am wondering how high It should be until I can get a meter. The tank itself is 7 Inches high. I do understand it doesn't matter as much during the cycle .. but just want to see what everyone else thinks.
