A favour to ask if you have a Hanna ULR PO4 reader and RO/DI

[Delphinus]

Heh, what a coincidence.

Darn it all that means we now need a third person to test to see if we're either normal, or both unlucky.

Thank you for doing that (and thanks for the tip re. the 3.066 factor which I had forgotten about )

No problem. I myself didn't know about it until about 2 weeks ago myself. Stumbled across it on RC.

delphinus - get in touch with the customer service at Spectrapure (ro/di filtration manufacturer) and tell them you have relatively high phosphates in your RO/DI water. They have a bunch of custom filters and DI resins for different types of water quality and they might be able to get you the correct selection of filters. I dont know if there is anything that will remove phosphates but you can give it a try.

EDIT~~~~ ok i found it.

this di resin should help kill some of your phosphates;



and i will even save you some money - here is a link to their holiday special - think its $22 bucks.

Funny this should come up, I was just talking to someone at a LFS the other day, they were telling me that they run their RODI water into a storage tank and then through two GFO reactors before running into their mixing bin, I thought it was just a tad OCD...Either way, I just changed the filters a couple weeks ago, tonight I'll pull out my Hanna and check.

I just ordered some of this last week... http://caco3reef.com/nuclear-di-oniz...esin-cartridge

Is it the same as listed in this quote?

[phi delt reefer]

no thats just regular DI Resin. The stuff sprectrapure sells is specially formulated for different applications. I think they have 3-4 different resins based on your water quality.

If makes any help my last canister of my RODI is is filled with HC-GFO never though tested for it, but I will tonight and post the results. HC-GFO is labeled to remove traces of metals that is not pulled out by your regular RODI system
