Phosphate Problem

Calm down,if DI resin is known to be good you have nothing to worry about.You are probably protected from po4 in rodi water.Now you can check the accuracy of your checker.That you can make with water with known po4 in it.But you certanly can not check po4 in rodi water because it does not have buffer in it,the same is with distilied water.Now you can make a salt mix with new rodi water and check.
The link you gave ,I think is a calibration fluid for hanna 736 meter.You can check the accuracy of your 736 checker with it.

Just a little bummed. I have had a Duncan in the tank for over a month, it won't open
and it's all shriveled up. That's the first coral I ever had. No matter how crappy the water was they were always open. Now everything checks good but phosphates, nitrates are a little high. I'm using BRS High Capacity GFO. I used double, then checked right out of the reactor. When checking the DI I did mix it with salt. So DI, tank, and out of reactor all
are about 0.10. Before this upgrade phosphates were 0.03 to 0.05. I won't feel good
until my readings are good. I ordered 25 more reagents and that standard kit. Should be
here tomorrow.

I added two additional chambers of resin to lower phosphates on my ro/di unit. It helped but still can't get absolute zero. I still get 8-15 ppb on my 736 meter.
I carbon dose and run gfo on the tank and always have close to zero on the meter when testing the tank. I'm sure it gets much higher though when feeding with the return shut down.

I hate phosphates my water off the ro unit was great even after salt mixture but the tank still has alot of phosphates turns out it was my old rock leaching it out after 8 years guess its time to take the rock out clean it up and replace with my backup rock on my newer tank..scratching my head as to why your getting those numbers bad meter or batch?

Received new reagent. It is a different lot. All tests came back the same.
The standard kit is used to check the accuracy of the meter. Meter readings
with the standard should be between 90-110. First meter 114 2nd 110.
According to the 2nd meter the tests are correct, I have high phosphates.
Maybe I will try to knock it down lanthanum chloride. Any advice on how to
use it.

Do you mean am I using RO/DI water for ATO. Yes.
How about this stuff.

I run a 6 stage r/o D/I, with 5 micron, then 1 micron then carbon then R/O membrane, then 2 D/I resin chambers. My TDS going in are 238 from my well, and coming out 0. I add Phosbuster to my water as I mix my salt to make sure I have no phosphates, and I also have no nitrates. My well water is .16 to .21 phosphates going into r/o and 0 nitrates

Buy some phosphate removing media (Phosguard or similar) and chuck that in the filtered water container and your tank. It's easier and a better long term solution than lanthanum chloride.
