They are good skimmers.Works good with a mag12 or equal. IME I would only use a skimmer with an auto shutoff= prevents floodiing. Even if it is in the sump I wouldn't want all the waste to go back in. IME Bullets are in the top catergory of skimmers
also take a look at the ETSS skimmers they have a complete line i can't believe the stuff it took out after replacing my old one i have a 75 gallon and use the 500 model and run it with a mag 9 pump
It is coming from my buddys lfs he allways gives me discounts and stuff and it is my local store it goes for $299 then i get a 10% discount so about $270 with no shipping what you think gol
I use a etss 800 pro on my 150 and it is pulling all kind of stuff I have a etss reef devil and it is really good skimmer I used it on my 150 till I got my 800 it pulled alot of dark stuff out too
IMO becket injector skimmers are much better than ets. They have the same pure power but beckets have a better or make much smaller bubbles= more contact time with the fatty cell you are removing. They are also less touchy. I have alot of experiance with ets skimmers. Aerofoamers,Bullets and Myreef skimmers are much better. If I couldn't have one of those I would then get Euroreef. They just a few things I don't like about Euroreef but they are good skmmers. Sure they're are alot better skimmers than the ones I mention= Self cleaning ect but we are talking a buget of a few hundred not thousand
