Big problem with di resin

Tap water is- 230 unsure of wht u mean by ro only if your talking about what it is putting out its 2

 

To troubleshoot a RO/DI you need three TDS readings, tap water TDS RO only TDS before the DI and the final or RO/DI TDS. Without all three you have no idea how well it is performing. If you do not have a DI bypass valve you can just disconnect the line between the RO membrane housing and the DI and test directly from the line.

 

will do and get back to you

 

i wonder if its even hooked up correctly no check this out
tap water going into resin camber out to taste odor chamber which goes to membrane then to anther taste odor chamber looking thing then out to bucket?

 

this looks correct?

 

The tap water should first enter a prefilter or possibly a carbon block which acts as both sediment and carbon if you do not have a prefilter. From there it goes in to the RO membrane housing on the end with a single line and screw off cap. From there it should come out the other end of the membrane housing via the line closest to the center axis of the housing and on to the DI filter. Unless you are making drinking water, throw the final taste and odor carbon filter away as it adds TDS and has no use in a reef system.
The waste should exit the membrane housing via the fitting closer to the outside edge of the housing and pass through the flow restrictor on it way to waste.

If it were me I would use a 1 micron prefilter, 1 micron carbon block, then the membrane and finish up with the DI but turn the DI chamber so it sits vertical and fills from the bottom and exits the top so it does not short circuit or channel as they do when horizontal.
If a carbon block acts as a prefilter too, the particulates, sediment and colloidal materials are fouling or plugging the tiny microscopic pores that adsorb the chlorine and VOCs so it does not last long before it allows chlorine to pass and melt the TFC membrane fabric.

 

The housing isn't labelled, so i don't know what's what in your diagram, but it should be:

Tap -> sediment filter -> carbon filter -> membrane -> DI resin.

 

thanks going to change it now

 

ok guys when it is hooked up correctly we have 0ppm amazing aint it thanks for knocking my head a little so i can think sometimes takes a couple heads lol
