Help Hana 713

Outrigger Reef · 09/01/2014, 06:24 PM

I have changed all filters, resin, and membrane in my ro/di system so the TDS are at zero. When I test the water with the Hana713 out of the ro/di system it is at .18. When I test the water in my top off container it is .19. When I test the water in my salt storage barrel it is .25.

I have had HA for a while now so I am trying to track down the problem. I only have five fish in my 90 DT with very little starter coral. New Reefbreeders photo 48.

What could be wrong with my ro/di system that I have .18 PO4 coming out of it?

Thank you for your help in advance.

I would try a different test testing supplier like Red Sea to run a sanity check on the Hanna test powder. I seem to recall some posts here about bad test materials. You could also invest in a jug go distilled water to cross check your number.

You could also have a bad batch of reagents. There was a lot number that was known to be bad a while back.
