R/O Water - Water that has been purified through the process of reverse osmosis. Also referred to as RO water.
I rebuilt my 3 ft tank with a UG plate and no uplift tubes, filled it with RO water prepared with Kent R/O Right, and reinstalled my filter - an internal Eheim sponge filter. At startup nitrates were predictably zero and rose gradually.
The container used was a simple plastic box (normally used to keep food in the refrigerator) filled with 60% fresh R/O water and 40% water from their original styrofoam box.
1/21/95 Replaced R/O filter media. Measured coral frags: M. digitata: 6cm x 4 cm; P. cactus 5.8cm x 5.1cm; A. elseyi: 4.6cm x 3.9cm; A. microthalmpta: 8.5cm x 6.3cm. I've been horribly neglecting this tank...

Seem to breed well when doing water changes with R/O water. These shrimp prefer lower water temperatures around a low 21.1°C (70°F) . Temperatures about 24.4°C (76°F) stress them out and they won't breed readily and may even die.
