Kinda curious......(RO FILTERS)

[350gt]

WHy is does BRS sell there reef kits with a 5 micron sediment and a 5 micron carbon filter while Buckeye sells there kits with a 1 micron sediment and 0.6 carbon filter...


Ive been blowing through these BRS kits and Im tired of it..... My membrane is semi new but will be ordering a back up just in case... The buckeye seemed to last a bit longer but its a plus ordering from BRS cause of all the other goods....

so what do you mean by blowing through them? maybe its some other factor or water in your area is that dirty?

I think the BFS carbon blocks are good for like 20,000 gallons no?

Well my DI resin turns brown really quick, but my in line meter still reads 0..... My water coming in is about 220.

Im just paranoid, Im getting a little cyano which I have never had in this tank and trying to find the culprit. I replaced one of my T5s, while I wait for my filters to ship....

I never had any issues when using the BUCKEYE filters and its seemed to start when switching to BRS..... Not saying that its the cause, I changed a few things within that time... but that was one.... I want to find which though...

the di changes quick from brs, i dont look at color i go by the tds coming out. so dont worry till it comes up and watch tds coming into di. i have my tds meter measuring in coming water to di resin and out, i also use a pressure gauge on incoming line to membrane when presure starts to drop compared to new filters i know its time to change the pre stage filters

[350gt]

cool.... I might just order a tds to measure before my DI........ thanks..

another tip i got from marc levenson was to purge water berfore di, this makes di last so much longer. the newer digital tds meter in his video is great i picked one up at macna and its very accurate.

Cool thanks again my reef-kenobi!

Cool thanks again my reef-kenobi!

i will slowy show you how to use the "reef force"

i felt the same way about quality also .... when i was buying threw buckeye i felt like everything lasted longer TDS wise but they dont have much else to order

HAD TO UPDATE THIS THREAD AS THE LINK CHRIS POSTED WAS A GREAT TIP!!!!!.....


I have been doing this for awhile after he posted the link and its amazing how high the TDS is coming out of the membrane for a few minutes..... FOR me, it starts around 120, then drops to 6 or under within a gallon.....

within that gallon you are saving your DI RESIN from having to eat up all that TDS, which extends the life of your RESIN.... I sometimes bottle the water in gallons and store in the fridge for my own consumption...... IT A WIN WIN in my book....

This burst of not-so-clean water when you first turn an RO system on is caused by a process called "TDS Creep." Here's some data from a couple of runs with a 75 gpd membrane:

So given this, you can see why its a good idea to make sure your RODI system doesn't short cycle - meaning turn on and off frequently. When your system comes on, you want it to stay on for an extended period of time. So if you leave the water supply to your system turned on all the time, AND if you run your DI output to a reservoir subject to evaporation (or to your sump), the system will turn on everytime the float drops just a hair and opens. That's why we developed the Hi-Lo Tank LEvel Controller.

thank you Russ its great having an actual sponsor chime in with his knowledge

No kidding!
