About This Product
This product allows you to relocate the probe (or multiple probes) from inside your aquarium (which can be an eyesore) and place it in return hose coming from your external cannister filter or sump line.
Most, if not all probes are 1/2" in diameter, so this is compatible with all on the market.
Unit comes with barbed hose fittings, so, please indicate ID of hose fitting needed. 1/2, 5/8, 3/4, or 1 inch.)
