Hey Guys,

I recently bought a new 75 GPD RO membrane from bulk reef supply to stick in my Coralife unit. The clean water output is normal (a little over 3 gallons per hour), but the waste line flows at the same rate. Here are the details:


- coralife 24 GPD unit
- replaced with 75 GPD membrane
- removed old flow restrictor from waste line
-installed new 75 GPD flow restrictor in waste line
- added DI component to clean line
- installed new sediment and carbon pre-filters

anyone got any ideas?

I also emailed Bulk Reef and they told me to test my output with a TDS meter. Is there any one with a TDS meter that would like to test my output :)

My 100gpd unit only puts out about 5g per hour depending on what the temperature is (warmer faster flow colder like now slower flow).

Did you replace the micron filter and/or carbon filter?

Why do they want to you check the output? I would think checking the water pressure would make more sense..

I have a TDS meter you can borrow. I'm in the city, Laurel Heights area.

I replaced the sediment filter with a new 5 micron and replaced the Carbon filter as well. I have the unit hooked up to a garden hose outside so the pressure should be good, right?

Hey badbread, thanks for the offer. Do you live near a BART station?

Almost sounds like there is a leak in the membrane.

I just finished taking apart everything that unscrews and I found a second flow restrictor in the 90 degree elbow that connects the waste line to the membrane housing. I think this is my problem.
