This pumps are excellent and works great in the coralbox skimmer.

Came on time. As described.

Bought as a back up for my skimmer which has been running faultlessly for 12 months. Great skimmer for the price!

The original pump stopped working. This pump fit right in my skimmer without having to do any modifications.

Fish-Street is the best! I did not find part for my pump anywhere else.

Like it says the pump in my Jebao D300 skimmer died somewhere between 2 & 3 years old. Options, new skimmer, new pump, well I didn't want to drop another $300 on a skimmer but had trouble finding just a pump. Thankfully I found one here at Fish-Street.com! Not some generic knock off either, a genuine, exact replacement, perfect fit and function. Skimmer is running like new, cant beat the price either. I assumed it would take typical overseas shipping time, I was wrong, I had it in about a week. Thanks Fish-Street!
