We will be setting up a Group Buy for them soon!!! I'll keep everyone posted.

jim,

i plan on starting a GB within the next few days so i can deliver at the frags swap. i just need to iron out the details with buckeye.

Sounds good steve ,

Welcome dude!! I need to change out all my filters too

 

[pecan2phat]

Buckeye is a great source for RO filter media needs. I started to purchase from them a few years ago and even without GB pricing, their prices are very reasonable. I bought from bulk DI resin to ARM media with them.

Nice Timing, never bought from them before, but I will buy some since I need to stock up

Hi folks - looking forward to working with you. At some point soon we'll have a Buckeye Forum where you can direct questions etc. our way.

Quick question. After changing out all filters, my TDS was at 30ppm; from a 580ppm. Do I need to change out the membrane? It is a couple of years old.

Hey Russ,

Welcome to MR :biggrin:

 

[reefman]

when should u change your membrane? and or DI resin?

 

[gforce6]

Great job, Steve
I need couple of things from them also.

I will keep my eye on GB.

Thanks Jung, we try to get the best for our MR community

i just bought 2 bags of dow flake from them!!!! just yesterday lol. HI buckeyefieldsupply.

 

[aaron23]

di resin changes colors. when the colors changed. change the resin. depending on your water quality in your area is when you change the membranes.

 

[bad coffee]

Welcome aboard! I have a box o stuff from Buckeye sitting here beside me!

Aaron, not all resin changes color. You should use a TDS meter as the real guage. When my TDS creeps up above 2 or so I change the cartridge no matter what it looks like.

Hi Steve - Can you provide some additional info to help troubleshoot your system?

Do you have an RO, or a RO/DI system?

Assuming you have a RO/DI, what is your TDS reading:
at the tap?
after to membrane but before the resin?
after the resin?

when should u change your membrane? and or DI resin?

Good question - Its addressed, along with the timing of changing the prefilters, in one of our FAQ responses:

A good rule of thumb is to replace your sediment filter and carbon block after six months. A more precise way to maximize the useable life of these two filters is to use a pressure gauge to identify when pressure reaching the membrane starts to decline. This is your indication one or both of the filters is beginning to clog.

Also be cognizant of the chlorine capacity of the carbon block. The Matrikx+1 (?Chlorine Guzzler?) for example will remove 99% of chlorine from 20,000 gallons of tap water presented at 1 gpm. Original equipment suppliers commonly provide carbon cartridges rated at 2,000 to 6,000 gallons.

Regarding your RO membrane and DI resin, use your TDS meter to measure, record, and track the tds (expressed in parts per million) in three places:
1. Tap water
2. After the RO but before the DI
3. After the DI.

The TDS in your tap water will likely range from about 50 ppm to upwards of 1000 parts per million (ppm). Common readings are 100 to 400 ppm. So for sake of discussion, let's say your tap water reads 400 ppm. That means that for every million parts of water, you have 400 parts of dissolved solids. How do we go about getting that TDS reading down to somewhere near zero?

If you do some experimenting with your TDS meter, you'll note that your sediment filter and carbon block filter (collectively called prefilters) do very little to remove dissolved solids. So with your tap water at 400 ppm, you can measure the water at the ?in? port on your RO housing and you'll see its still approximately 400 ppm.

The RO membrane is really the workhorse of the system. It removes most of the TDS, some membranes to a greater extent than others. For instance, 100 gpd Filmtec membranes have a rejection rate of 90% (i.e., they reject 90% of the dissolved solids in feed water). So the purified water coming from your 100 gpd membrane would be about 40 ppm (a 90% reduction). Filmtec 75 gpd (and below) membranes produce less purified water (aka ?permeate?), but have a higher rejection rate (96 to 98%). The life span of a RO membrane is dependant upon how much water you run through it, and how dirty the water is. Membranes can function well for a year, two years, or more. To test the membrane, measure the total dissolved solids (TDS) in the water coming in to the membrane, and in the purified water (permeate) produced by the membrane. Compare that to the membrane?s advertised rejection rate, and to the same reading you recorded when the membrane was new. How do you measure TDS? Membranes also commonly produce less water as their function declines.

After the RO membrane, water will flow to your DI housing. DI resin in good condition will reduce the 40 ppm water down to 0 or 1 ppm. When the DI output starts creeping up from 0 or 1 ppm to 3 ppm, 5 ppm, and higher, you know that your resin needs to be replaced. Sometimes people complain that their DI resin didn't last very long. Often the culprit is a malfunctioning RO membrane sending the DI resin ?dirty? water. This will exhaust the resin quicker then would otherwise have been the case. Sometimes the problem is poor quality resin ? remember that all resins are not created equal!

Welcome aboard!

How much would a full cubic foot of color changing DI resin run us? We're having an upcoming frag swap and it would be good to stock up. I have a feeling it will get used and not sit around for too long.
