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

[Ryan-b]

If its the phosphorous UL reader you have to convert it by multiplying the number you get by 3.066 then dividing by 1000. So if it is showing 11 ppb. It would actually be .0337 ppm.

Give me a couple mins and I will test mine.

Oh right, someone was telling me about this the other day. Geez, you'd think they'd put something like that in the instructions.

That's actually not good news. It means my PO4 is way higher than I thought it was - both in the tank (which explains a lot) AND in my RO/DI (which probably explains why the tank is the way it is). Geeeeeez.

Thanks!

Funny yours is 11 that's what mine just read and the filters are all less then a month old. And that was straight from the unit

[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.
