Where do you buy your replacement filters & RO membranes?

[TonyD1988]

I love buying stuff from BRS but I go through filters somewhat fast. Is there any other vendors that sell replacement filters and RO membranes for cheaper for the BRS 4 stage RODI system?

I use amazon

I get mine from BRS. How fast are you going through filters though? My water is relatively clean (< 190 ppm TDS), but my prefilters are 3 years old now, and my membrane is 4 years old. No detectable chlorine in the brine (waste water), no pressure drop, normal rejection rate, etc.

Unless your tap water TDS is very high or your source water has a lot of chlorine, you shouldn't have to replace your filters that often.

i get mine from brs too.. are you purging your RO/DI before and after use?

Well I replaced my sediment, DI, and carbon block filters around 4-5 months ago but since then I've stocked a 300 gallon and maintained a 145 gallon while doing water changes/top offs on both of them. I've had the original RO membrane installed since I got the system almost 2 years ago but since added the 150 GPD upgrade kit so a new RO membrane. Do you think replacing those two would be the fix? I purge the membranes before making water and incoming TDS is less than 10. It is now at 1 as of last night.

I purge before use but not after. Maybe just the RO membranes need changed? I have the original one installed from almost 2 years ago but the 150 GPD upgrade kit installed about a year ago.

I only replace my prefilters once a year just because I feel like it. I change the membranes every 2 years and my resin when it needs it.

do you have a TDS meter and a pressure guage? maybe your RO membrane is indeed old.. i only ask if you have a pressure guage as RO membranes have specific psi to work properly.. but i could be wrong on that too..

Amazon has a kit from Aqua FX that will replace all your elements and RO membrane. You only have to add an additional membrane and it's inexpensive.

What problem were you hoping to fix?

Sorry I am a little out of it today lol. The problem I have is I already have 1 TDS coming out of the filters when I feel like my filters aren't that old. Incoming TDS is less than 10.

Where are you seeing 1 ppm TDS? After your DI resin?

I'd have to look at the system and see where it reads it. Its the BRS 4 stage with TDS meter and pressure gauge. The TDS meter has an "in" and an "out". The out is at 1 now. I know that probably isn't much to worry about especially considering its for a FOWLR tank but I like to keep it at 0.

Old thread but didn't seem like this question deserved a brand new thread so,,, especially for those that mentioned Amazon...

Due to change my 2 BRS Universal 1 micron carbon blocks (in BRS 6 stage plus RO/DI unit),,, and have a bunch of Amazon gift cards to spend.

Does this seem like a reasonable alternative to BRS carbon blocks,,, or any better suggestions on Amazon (even if more expensive):
