Sleeves are fine. I have a problem with the MarineLand filtration system itself. We have had an aquarium for about 15 years and have never had algae. Unfortunately, since we installed the new system, we have had to completely drain and clean everything about 3 times in the last few months. I'm not pointing fingers or trying to insult the company, but otherwise nothing has changed at the aquarium. Any ideas what could be causing this? I welcome any ideas you can give me. Thanks Teresa
