180 gallon build: Modular control system, 3D printed equipment, open-source

Have you experimented with Petg yet? I am floundering trying to make a decision on if I want my submersible prints ABS or petg.

PETG is fine, and doesn't have the fumes during printing that ABS does. I've printed 10+ spools of PETG so far.

It is a bit of a pain to get dialed in, tougher than PLA, and I recommend an enclosure for repeatability.
 
Are you using the PETG submerged in your tank at all? Any issues? Once dialed in are vfc the prints as watertight as ABS?

I appreciate the info!

Yep, using PETG underwater. I have had issues with getting things water tight. I have been coating my brine shrimp hatcheries with a layer of epoxy, thinned with alcohol.
