I ordered the 200w with the controller. They were 25% of so it was like $63 bucks. I ordered a bunch of necessities to tide me over until after Xmas, couple boxes of salt, some replacement filters and resins for my RODI unit, etc.. and I saw the sale and figured now was the time. Spent more than I wanted to but I needed it. The Neotherm has been great but I don’t trust heaters to last no matter how well they work and going with something smaller is appealing. Having backups on hand is one of my goals at the moment. Right now my backup return pump is the original no name one that came with the tank. I really hope I don’t have to use that before I can get a new one and use the CurrentUSA as the backup. I also wouldn’t mind having a backup EB832 power unit for the apex but I can get away with using the dj switch for a period of time if I have to. I’m glad I have it hooked up. It powers the light and the uv at the moment because there’s no need for them to be on the apex.I'm using the BRS heater and so far so good. I went with the 200W but wonder if I could have got away with the 100W? It's hard to judge, particularly in the summer when it only has to raise the temperature about 2 degrees instead of around 10 in the winter but time will tell! On the definite plus side, it is nice and compact and short enough to even fit into chamber 2. That's one thing about this shallow tank, heater choices seem very limited. There is no way my 125W Eheim Jager would ever fit.
