I have two bm skimmers and they have been trouble free so far. Easy to set up and adjust. I would go with one that's rated for nearly twice the total volume of water in your system. Only drawback I've found is the pumps are large and a little noisy but I don't hear them in the stand anyway. There are better skimmers out there but I don't see the need to spend the extra money personally just to get a better quality pump. The skimmer design is pretty much the same for all the cone skimmers. I can see a better quality skimmer being required for those with high end equipment but for the average reefer it's probably more than enough. Of course I what to make it clean this is just my opinion and there's no topic on here that won't generate differing opinions.
