Which magnet cleaner?

[vapormd]

Roger,

I have a 200g tank made from 1" thick acrylic and was wondering if the 220.55 magnet cleaner would be sufficiently strong. The price jump from the 220.55 to 220.56 is fairly high, so it would be great if the 220.55 is sufficient. Also, I know a little while back, they were on backorder - is this still the case?

Thanks!

I have them in stock the 220.55 will work OK, if you get moving fast though it could slip and it won't work on the toughest algaes but the .56 or any magnet for that matter is not ideally suited for much beyond diatoms and fresh algae growths that are not really hard to remove.
