Just did a quick check on the progress of my Turbo’s Aquatics L2 Rev4 ATS. It has been running for about 4 weeks now. It’s running on a brand new tank and the screen has been sitting in my rock curing tub for a few months prior to setting up the scrubber. I have it at about 25% intensity with the potentiometer dimming knob at the 6 o’clock position, running for about 9 hours a day opposite of my DT lights. I was expecting the slime growth stage, common with most ATS screen break in periods. To my surprise, I have a nice and even layer of firmly attached hair algae developing on the screen. I may look into either upping the intensity or increasing the photoperiod to get some faster growth now that the screen seems to have broken in properly. Very impressed with the performance of this ATS thus far... Thanks Bud!
