I use speedwave 690gph as my return; cranked up to full so probably throwing around 400 or less at the return in the tank. Some people want high flow through the sump, some don't. But I would say, since its a mag and cannot be controlled, 1200gph might be a bit overkill. Go for a DC pump. Easy on the electricity, less noise, controllable and costs same as other pumps.

Not sure what a herbie is . Sorry still noob . Priced a knew dc pump at 160 but my buddy's selling a mag 12 for 80. I could always gate valve it to slow it down. Also going to run a reactor off it . It going to be a money tight tank till further notice
