I'm currently in the market for at least two new protein skimmers. I don't run sumps, so I'd prefer them to be in-tank. I'm open to HOB skimmers, but am a bit nervous due to some previous experiences with them leaking saltwater onto my apartment's carpet. And, no, I don't want to add sumps - I understand the benefits, but don't want to deal with it until I'm in a home I own.
I'd like to get a skimmer for my 40 gallon, which just houses my Green Spotted Puffer, and my 55 gallon, which houses a Peacock Mantis Shrimp, 2 Clarkii Clowns, a Yellowtail Damsel, an Azure Damsel, and a 3-stripe damsel. I'd like to keep it as cheap as possible, but I don't want to bother with something that's going to fail in 6 months, either.
