I'm looking at getting an ATO, which ones work well and what should I look out for? I looked at the hydrofill ATO and it looked easy to setup and like it would work well.... Also looking at some sort of auto water change system... But that's another topic. Sent from my iPhone using Tapatalk - now Free
i agree, an ATO is a must have for ease of upkeep on your tank. I use the Tunze Osmolator as well, but if it had been available, I would've tried the Hydor or the Innovative Marine ones. They look to be more foolproof.
