Once or maybe twice a month on the front glass.
Wow, once a month only? I'm jealous. Is it that infrequent because nothing grows on the glass or because you can't see through it anymore.

Once or maybe twice a month on the front glass.
i use ro/di water and i still clean my glass weekly to make it look "show room"
Also I added in four more snails yesterday
I have 5 grandkids who just love taking turns with the MagFloat, front and both sides, never the back, I leave that for the critters to fight over!
Get a length of small pvc long enough to reach the bottom. Using a hacksaw, cut a diagonal slit in one end. Insert razor blade and presto, a handy scraper that didn't cost much. By the way, the other end of this thing has a little toothbrush stuck in it. That comes in handy now and then.

I don't encourage adults to use it either.
Clean glass once a week like clockwork w/ a window (plastic) squeegee, stays show room quality for about 3 days and nice for 5 days and kinda hazy for 2 days.

I've made it into a habit of cleaning the glass with a magnet cleaner once a day. It helps by slowing down the coralline algae growth, but best of all I see my snails spending less time on the glass and more time on the rocks.
