Ok so I still haven't built the first SM 200 besides the prototype. I hope to start on it this week. Anyways, I'm still a bit miffed with the prototype as far as algal growth. It probably is a flow issue but it's still pissing me off. I'm getting bands of dark green :slime" growth at the top and bottom of the screen, and yellow slime in the middle. Its fiberous slime, but still slime. There is a little purple slime mixed in. When its scraped off it smells sickly sweet. I'm getting no algal green ling hair growth at all. However, my frag tank, which has a 15k 175 watt MH with no herbivores in it is growing hair algae and bubble algae like no tomorrow.
I'm getting about 1 cup of slime per side of the 24 inch screen.
I'm worried that I'm going to build the prototype and have too much light on each side. To recap I'll be using 1" plumbing and I'll have about 45 gph per inch.
