Could you replace RO/DI unit with Reactor?

[Fcamdog]

Out of the tap my TDS meter reads 140ppm. Not too shabby for drinking water but not clean enough for reef applications. I do use RO/DI that measures at 0ppm for my tanks.

Here is my question, do you think it would be reef safe to take tap water, run a dual chamber reactor with GFO and Carbon vice using RO/DI water?

Carbon eliminates a lot of nasty and the GFO gets rid of phosphates and heavy medals. This is what we do not want in our tanks.

Thoughts? Discussion? I am about to order a dual chamber reactor and run some tests on our local tap water in Clarksville just to see. Thanks,

you will still get readings on your TDS. you need RO/Di.

+1 the DI part is what removes the rest of what the sediment/Carbon miss. You can not get the 0 tds water you need from your Idea.

I would have to agree. Neat idea just dont think the reactor will be able to get everything out of the water you want.

Yeah, carbon and GFO will not remove the worst stuff alone.

Carbon gfo won't filter dissolved metals and small particles...it's why you use a membrane. The pre filters are to help extend the life of your membrane. You need a minimum of and ro unit. Ro with a di unit is best as everyone else mentioned.

Sounds like you are trying to do what a Kold-Steril system does - take out the nasties, leave the calcium and magnesium....
