I would look at the ATB 1050a for now it would work when you upgrade but might be a little small. ITs hard to say use this skimmer and then it will work well for a system twice the size. it just doesnt work that way.
When you start dropping some serious money on a skimmer and you need good customer service. And well ATB has the best service I have ever had. I have had good experience with the following as well. Marine solutions, Reef specialty, Warner marine, premium aquatics, Aquarium specialty and others. But when you can deal with the company direct it makes life easier.
When the performance playing field levels out then you look at the other areas that set it apart.The longer I am around skimmers and the more I see. I ont think I would buy a high dollar bk skimmer anymore. I like them, they are built well. But it can be hard to get parts for sometimes and they are expensive. This is my opinion. And you all can agree. I do like the mini's for smalelr footprints and would be happy to own another. But not if I had to apy for it.If you have any issues you have to go through the people you bought it from. I like dealing with the supplier direct whenever possible.
