I had issues with Aerobic bacteria in my aquarium. After months of unresolved attempts (per professional suggestions) at resolving the problem, I got rid of the Marineland filter/biowheel system. After performing another partial water change, I replaced it with another brand, after approximately 7-10 days, I had nice crystal clear water. I've been using the same system now for 2 years and couldn't be happier. I'm not allowed to name the other brand, but it's also advertised on this site.

My water is perfect in PH......what else can I ask. I use two pumps per tank. One in the smaller one. I made a mistake with some substrate and the waster was milk. Within about an hour the tank was just about to normal. I love that this helps me with the effort of keeping a clean crystal PH balanced tank. Thank-you

Changing the filter is easy. I actually wash my filter out and reuse them a few times.
