The ReefBreeders Magnetic RODI/ATO safety float fits standard 1/4" RODI tubing. These include a sturdy magnet mount that works with glass up to 3/8" thick. The unit is designed to be placed a few inches above your desired water level. If your ATO were to siphon, have the pump run too long, etc. this float switch will physically cut off the flow of water, preventing an overflow. It may also be used directly in your ATO reservoir to keep it filled via a siphon from your RODI water tub, removing the chore of dragging buckets to your sump once and for all! No ATO has a 0% failure rate, so these are an excellent addition to any ATO system to add redundancy and safety to your aquarium. These are also super useful for RODI systems, you can mount this in any bucket or aquarium, with no drill hole required.
