my RO water

[padi200]

So since I have RO water, not RO/DI for now, I wonder, can I add phosphate binding media to my top off water holding container, maybe a bag of it, to help get rid of the residual phosphate?

i am sorry for the multiple posting, my internet explorer was sick! i think i fixed it now.. once again, sorry

I think it would serve you better in the sump or in a reactor to take the phosphate out of your tank . The residual in ro is likely much less tahn what you put in with food.

I have a reactor and a bag in the sump too

Most phosphate medias rely on multiple passes to work, a bag without water continously passing through it will have little effect on removal if any.

So I would be better off just adding a DI unit onto my existing RO unit? Marine Depot sells one, I think?

So does Buckeye Field Supply and Bulk Reef Supply, both great places to purchase from and possibly cheaper.

And Bulk Reef Supply had phosphate media and carbon way less expensive too. Thanks!
I just created my account there.

Wow, just looked at Buckey.

Or this one?

Yes, adding a DI or better yet dual DI to your RO is a wise investment. I use and recommend the Spectrapure MaxCap dual DI myself as there is nothing else like it on the market.

The DI in the LA area would be more for dealing with Chloramine. Unlike Chlorine that is effectively filtered out with a Carbon prefilter the Chloramine that they use to treat water around here is not effectively taken out by Carbon media. So what happens is it traces pass right thru the Carbon and RO membrane and can give you a positive Ammonia reading in the tank.

I would think you would be better off adding a DI add on kit to your RO system and using the phosphate media in your tank with a media reactor.
