Sump too close, can’t use ATO

[Krully]

Thank you for your help and discussion on the matter. Since apparently both halves are waterproof I'll probably just put the "outside" one in a zip-bag just to double proof it for now and put the magnet in the water. You guys confirmed what I was thinking and I should not put it anywhere but in the return chamber.

I've found another thread where rvitko states they are indeed submersible : https://www.reef2reef.com/threads/a...tor-3155-magnets-able-to-be-submerged.615522/
