Hey everyone, I have one simple question. I have been in the hopby for about 5 years. I had a 150 set up and then a 75 set up about 2 years ago. I have not had anything up sence that time. I desided to get back into the hobby recentaly. I am setting up a 20 gal reef tank due to the cost difference of the 75 and 150. I have all my old stuff and I want to know if you think its going to be to much. Here is the equiptment: A 75 gal wet dry, Sealife proten skimer( I don't remember the model), 9w turbo twister uv. Here is my big problem, the pump. I have a model 24 which pumps 2400gph. Will that be to much for the 20gal. Also I have a 175MH for lighting is that ok to if I mount it like 10" high? Thank you very much for your help..
