Reef safe Solenoid valve. WHere to get them??

[banditpowdercoat]

I'm building a PLC controlled ATO for all my tanks. The goal is to have independent RO/DI fill control for my 4 tanks out of a reservoir, and control the RO/DI unit to auto flush and fill the reservoir. The Float switches I have seen, and aquired before on Ebay(If anyone has a bunch to sell, I'm looking) But where am I to get 120V solenoids that will be reef safe??? I estimate I will need atleast 6 of them, so hopefully they are not $50ea+ LOL

Thx for your help
