I don't know...I'm starting to thing the ETSS and Bullet style skimmers are getting outdated. They do work great, but you can get a needle or mesh wheel skimmer that works just as well for less money. And they don't need a huge pump to run them either.
Needle wheel & mesh wheel skimmers work awesome when first put online. But there performance downgrades with short time use. Especially if it is in sump & there is alot of detrius that collects there. (alot of those type skimmers are in sump use) Anytime you stir it up or the particles are water born in the sump the mesh & needle wheel skimmer style pumps will suck it up & it will get trapped inside the mesh or the small needle pins cutting down bubble production. Yes they use very little wattage but again because of this it doesn't take them much to be hampered by production due to the wheel & mesh getting clogged up. The bigger style skimmers with large pumps are not effected by this as much. Unless you suck up one of those small snails that live in most sumps & it gets stuck in the vanes of the impellar. Which is very hard to do with a pickup screen attached to the intake.I don't know...I'm starting to thing the ETSS and Bullet style skimmers are getting outdated.

This exact same thing use to happen to my PM bullet becket style skimmer and I would get 4-5 snails stuck in the becket every couple days and would have to take it apart 1-2 times a week because of this.Unless you suck up one of those small snails that live in most sumps & it gets stuck in the vanes of the impellar.
