So here’s my experience with calcium reactors. I was in the same boat as you and using a large amount of 2 part. About 200ml a day of each. I switched to a calcium reactor and got it dialed in dripping with a kamoer and everything was great. My fatal flaw was in used a reactor that was too small...
I have a 24x24x10” acrylic with a stand. It’s in really good shape but I never got around to painting the front door. It’s currently empty as I used it mostly for nems. You can PM me if you have more questions
This is steal for this tank, I have personally owned a 72x36x22 CDA tank and the build quality is great. If I could convince my wife to buy another tank I would of but this is a great price people
Usually if you have a decent amount of stalk so you can cut it up. I have a hellfire torch with about 30 heads but I would have to group them into about 5 heads each because the stalk is not long enough so you just have to pull it out and see what you can cut off
The motor can be somewhat loud, more so if your sump area is open and not in a cabinet. I have a 2 1200's and 1 500 and Ive noticed they all work better if the water level is essentially right above the pipe where water enters from the bottom. You will have most of the body above water level.
