ICP/RODI ASSISTANCE

[Tigerito]

Hello,

I have a mature 134 Gallon sps Dominate tank and noticed my Phos climbing slightly and also hadn't done a ICP test in a while so sent 1 in. My ICP is showing Phospherus in my RODI water which is strange because I have a 7 stage overkill and I also make sure I always have 0 TDS leaving the system. I'm wondering what I can do to prevent this. Going to order another icp to double check.

I also have always shown high pottasium on every icp I have done in 5 months and was curious if they was a concern. I showed it while using redsea salt and now with using tropic marine. I don't dose any potassium.

The vendor measures phosphorous and calculates the amount of phosphate this could be. Your results are actually showing no more than 0.004 ppm PO4. That is, multiplying the P measurement by 3 and dividing by 1000. Also, since the ICP vendor is not guaranteeing accuracy of there results for phosphorous, it can be an iffy measurement, there really isn’t an issue here,

Right I use Phosphate tester from hanna and show nothing close to this. And there also showing this [picture] for phosphate and nitrate which doesn't make since and is WAY off from what I am getting

The 1 ug/l in the ro/di is quite low and no concern. Their comment it is critically high is ludicrous.
