Protein Skimmer and Coral issues

[Antrias]

I will pick up another kit and retest calcium... I retested everything today and it looked good.

However my RODI unit is doing a terrible job. My tap water comes out at 200~ the RODI is only putting it to 170~... my Britta filter gets it to 150~! I think my house water pressure is just to ****ty.

You can buy a booster pump for under a hundred bucks that will boost that pressure for your RODI and get it working properly again.

Are you on a well, or city water?
What is the pressure? It should be at least 60psi
If you have that, then your membrane has a hole in it. And your DI filter is depleted. Barring everything else, your DI will bring the TDS down to 0.
Check the TDS of the water coming out of the ro membrane. It should be about 95% less than your tap water.

I am on city water - it could be I don't know what i am doing with the unit but i also am sure that the DI resin is depleted now that you mention it. The unit has like a valve at the waste water line that if I keep it mostly closed i get close to 60PSI however if I fully open it i get maybe 20PSI.

Are you sure your rodi unit is connected properly.....sounds like their is no flow restricter installed or the flush valve is open

+1
That valve is for flushing the membrane.
