So i rented a par meter the other day and wanted to share my findings for someone that may not want to rent one or have the ability to rent one. I am using the Ai Hydra 32 on a 40 gallon breeder tank with the HMS Single Light Mount Kit by Aqua Illumination mounted at max height. All readings were taken about 2.5" above the bottom. I have my light strength settings below. This is just something I wish I had access to when programming the light settings. For the record this is a LPS tank that currently has a mushroom, zoas, & a toadstool. All have been very happy and showing good color. Upon testing I bumped everything up to the 60% mark since the 50% was looking a little weak.
