Thanks, I just have the diffuser (aka egg crate, bought at Home Depot for $12) covering the tank. It's purely there just do I can place the lights on top. Once I build my DIY canopy for the LED
floodlights will probably take it off. I usually keep my tanks topless because I like to get maximum gas exchange. This tank (72G + 30G sump) does evaporate over a gallon per day, but I don't mind filling up the ATO (auto top off) every few days. I just see that as the cost of getting better gas exchange.
By brand are you referring to the LEDs? If so, they seem to be brand-less! If you search "LED
floodlight" on eBay you will see hundreds of these gray or black painted metal floodlights, they all appear to be the same "brand". On my DT (display tank) I found some 20W 12000K lights, on my sump I have a 10W 6500K light that has been promoting the growth of my macro algae. All round I am very pleased and surprised with the results, I'm sure an $800 LED
light fixture is superior but this seems to do the job for far cheaper, how will do in the long run? All looks good so far.
