This is my 30 gal freshwater tank. Divided, 2 Betta's, 2 Ghost Shrimp, 1 Bristlenose Pleco, 2 ADF's, 3 Mickey Mouse Platties, 2 Rasbora and 2 Zebra, 1 Raphael Catfish.
My screen is 4x5 and I have a 23 watt, 2750 K bulb, single sided but reflectors behind the bulb and the screen. I've gotten some green on the screen, but it was very light and my Am, Ites and Ates are out of sight. Feeding is the equivalent of 1/2 cube per day.
Do I need a 42 watt bulb?
My solar, waterfall scrubber keeps my 140 gal pond crystal clear. Yaay SM.
Thanks, Tony
