A few Q's for the more Knowledgable.

Hey,

I'm farily new to CanReef and the SW world. I've been on the fence about setting up a smaller 20-30G Reef tank with a 10-15G Sump. I need a few quick questions cleared up.

First I was wondering what size over drain holes would be great for draining. It will be harder to explain without pictures but I"ll try. I figure I would make 1 Drain pumped up into 1 return. I also plan on having a power head to create flow against the return flow coming from the sump across my Nano reef.

Also what size sump pump would I need to look at? GPH? Min/Max? I plan on going with a Bio Filter w/ Live Rock and a Ref in the Sump.

Any tips on a great sump design, at this time I don't plan on going with a skimmer. I have a Sump in mind but I wouldn't mind some suggestions.

I believe i'm going to be purchasing a 1 250W MH 4-T5HO Lighting system.

Anyways that's all for now I appreciate any replies, feel free to PM me as well.
