I repair the KZ skimmer - it wasn't drawing any air or producing the right foam I expect from a kz skimmer. I replaced the pump with an identical flow eheim rather than the stock pump as it was quite loud and thought to be the issue at first. Then noticed there was water escaping the skimmer at a few of the silicone seals. I've re-sealed them and the skimmer is now performing as expected and quieter.
