diy algae magnet

[rng_pw]

Has anyone ever built there own algae magnet? I have a 1" thick acrylic tank and I don't want to spend $200.00 on a magnet lol. I've used neodymium magnets before to make frag racks, I imagine it should be similar. I'm just not sure how strong of a magnet I need. Any advice? Thanks

i just use my magnetic cleaner to hold my algae. get some rare earth magnets they should be strong enough to hold

I should be more specific. Diy mag float or magnevore? Thanks
