I was wondering how people get high PAR in their tanks? I have a custom 70gal pond/tank 36"L x 24"W x 19"H and I have a quad T5 HO bulb set up 8" from the top of the water, an at the brightest spot my PAR is only 50-75. I know that's a big jump but it's been awhile since I checked it an this was when the bulbs were old. The 75 was when I sat the light right on top of the tank. I read of others havin 100+ PAR or even 200+ an I'm just wondering how, I have to add that everything with my tank is fine I'm just askin for MOI that's all?
Wanted to know if anyone tried T5 HO bulbs with LEDs for daytime lights? I was thinking of adding some to my set up as I have dark spots in the front and back of the tank cuz of the 24" width, I can't find a aquarium light to cover my whole tank but I have found other lights cheaper that come with 6-12 T5 HO bulbs. I was gonna look into one of those first.
