Michael's 300 In Vegas

[Coral reefer]

I ordered the one size up, so it is 5/8" - 1 1/4", so with the algae scraper it is still centered at 3/4" glass. And I have a spacer to "weaken" the field. But seriously, these magnets are no joke. My other smaller ones can hurt a finger badly, these would be catastrophic.

I’ve never used the scraper attachment actually. Just the algae cutter mesh bags/socks

Keep away from small humans!!

Got two sheets of 3/4" plywood over there now, and filled it up to 50 gallons with no noticeable flex in any bad directions.
