Rodi issue maybe?

I have a booster. Running the unit at the right pressure, extends life of membrane. I was running bare minimum pressure before, now have my booster set at 75psi, makes water a lot faster!

It had ran for a few days Already, just went to VIP which is in my area and got carbon and ammonia cartridges for the Rodi, will be changing out right now, hoping this finally settles things down in the tank. Need to find a booster pump also, maybe that will increase my reject rates.

What pressure is it running at now? Also what size membrane?

Cartridges I got local, got the membrane online CSM brand.

Its been a while for me since I bought a membrane but i think CSM does not have the rejection rate you want. Most aquarium RO membranes use TFM.

Others can chime in.

Don't know the pressure, the membrane is an 80g per day.

Aquaman went to look up the reject rates based on your comments and the CSM (98) has a higher reject rate than the TFM (96). I didnt check that before but seems to be ok.
