Here is some magnet advice I can share. I mix my magnets up with a Magnavore 8 and a mago float on many of the tanks I clean. I also would never use a mago float as is. I think they suck unless you put a dobie scotch brite pad "sock on it. The Dobie turns even a mago float into something that can work well. You never have to replace your mago float then. It works great on acrylic tanks as well. This tip allows me to clean 8 tanks a day, everyday without breaking a sweat. On real thick tanks (like a 3 thousand I clean I double and triple up on magnets and turn them into monster magnets. If anyone wants a lesson on making a magoflaot work, I'd be happy to help teach you.

Magfloat and dobie should clean a 100 gallon tank real easy. also when using the dobie go with the grain of the grit. That means the long way of the mago float. not the short end. that way the mago float will not pop off.

Cut the yellow sponge out. insert your magnet in its place.
