Introducing the Ultimate Coral Fragging Solution: Our Magnetic Frag Rack!

I've had PLA products delaminate over time. It takes an awful long time for it to happen, on the order of 3 years, but it happened.
We do not print any of our products in PLA filament, we only print everything in a reef-safe PETG filament.

Interestingly enough in this experiment they found PLA to not be as biodegradable as claimed.

"All other so-called (bio)degradable polymers (PCL and PLA) did not show any significant degradability under tested conditions. Degradation rates of polymers were relatively same in FW and SW"

That matches my anecdotal experience.

Slight detour; I keep seeing people say that PLA will break down in saltwater, but I've yet to see it happen.

I've printed a few small items from PLA, like my reef diaper media holders, and they've been in use for a year and they're no worse for wear.

I don't doubt that PETG is the better choice and I almost always use it for aquarium items, just curious as to where the PLA rumor came from and if it's actually true.

Can the "outside" magnets be placed in a tank?
I want to put it in the back of an aio tank.
