These were great guys! I managed to make a cheap ATO out of a float switch I pulled out of an old A/C condensate pump, a fountain pump from an old desktop fountain that was in our 'to get rid of pile,' some ice maker line and a milk jug. On top of that, my wife is getting a lot more comfortable doing tank maintenance/testing and really enjoying it! I appreciate all of the ideas and inspiration. I may go with something like the Tunze Osmolator when we upgrade our tank but I've got something that works for now! I felt really stupid after Bulk Reef Supply emailed me back what they did but now I feel like a mad scientist! Lol! Guess I'll take my business elsewhere and my future questions in the hobby will go right here!!! Thanks again!
