Do you use RO water only ? Or DI as well in your reef ?

Hi,
I am wondering if an RO water system is enough for a reef tank, Or is the DI Chamber required.

Thanks

You want to go with DI too, especially if you are mostly sps as your signature says. I run my RO water through two DI chambers

Thanks CoralMonkey,
I went out and picked up a separate canister and Di cartridge today after reading your response. I am going to connect it up to my R/O filter.

I run 2 di canisters as well. When my tds goes above 1, I move the second di resin to the first canister and install new di resin in the second to try to get maximum use from the resins

Compared to the problem not using one could cause and in general the low cost I'd use DI without question. You can do 2 cartridges or just test your water with a tds meter.

I would go with DI.

Ro/di!!!!

DI, much cleaner water. I also use two chamber(c/a) after RO, with block carbon before them, it seems that my DI last longer with it.

I'm ro/di but still see great tanks on tap water

Was at petco yesterday watching a worker mix salt water. Using tap water and mixing in aquasafe and salt, he was using it for top off water lol, you should have seen there hair algea problem, along with the dead corals they were selling, i asked him if they were alive, he said oh yes definately....... di cartridge all the way!!

Adding a DI to your RO unit is about $50. That's nothing and you get the benefit of truly pure water for your reef. Go RODI and you can rule out your water source being a problem when it comes to algae.

Thanks everyone for the great advice,
I am going to hook up the DI cartridge I just bought and then test it and see how things go from there.
