i have been very happy with my mr1 by 'my reef creations' (they are a sponser of trt), they my cost a little more than some but the quality of these unit is awsome. also they do pull alot of goo out of the water. always remember that you get what you pay for. i bought a red
sea prizm, which is for sale by the way, but was less than happy with performance. as far as a sump set up you have many options, myself i have an aga with some acrylic pieces i cut and siliconed in there and life is good. btw welcome to trt. there is an awsome amount of information here, just do a search for sumps and you will find many threads about them. good luck
