Carbon Snake before RO/DI

[rage]

carbon bottle/snake in comparison to the carbon stage of the RO/DI.

Which carbon stage? Why do you want to replace a carbon stage with another carbon stage anyhow?
How does that make it 10x or 100x better?

[eklikewhoa]

What kind of carbon snake are you talking about?
x10 or x100 better than the 1st stage of a RO/DI? Which stage is that? An RO/ DI could have 3 stages before the RO membrane.

this is in reply to your question above... the CARBON stage

Not to replace anything but to add to.

The large carbon bottle would remove chlorine and any sediment in the water prior to the RO/DI filter thus extending the life of your RO/DI since it would not have to do as much in this category on it's own and I did not say better but it would be 10-100x more carbon filtering depending on the size carbon bottle pre-filter you use.

Well , it looks like all is good. I finished glueing the pvc and plumbing it to the RODI unit. I turned it on after work and I am definately gettting some RO water. Its raining over here so that is getting mixed in the 75 gallon Rubbermaid tub as well. I have a few cherry shrimp but mostly crs shrimp in there now. I hope they start producing for me. They don't seem interested in the barley pellets like the cherry's though.

A decent RO/ DI system already has
1) A sediment filter.
2) Catalytic GAC filter
3) A carbon block filter
The GAC is in a 10" x 2.5" cartridge.

Do you suggest to add a carbon snake that has 10x or 100x as much carbon?

The RO/DI filter is sufficient as it is and will work greatly for you.

76dragon asked about adding his carbon snake/bottle as a pre-filter to his RO/DI since he already has both.

-The carbon pre-filter will extend the life of your RO/DI system (as stated multiple times now)
-The carbon filter is not a necessary item needed to run your RO/DI system
-If I had both Carbon bottle/snake and a RO/DI system I PERSONALLY would utilize my resources and run the carbon before the RO/DI
-If you have the money to run a carbon bottle as a pre-filter to your RO/DI I would indeed suggest doing so
-A carbon snake/bottle does indeed hold a lot more carbon than a RO/DI filter which is clear when comparing the size difference
-The amount of carbon in the RO/DI is clearly sufficient for the job as your TDS readings of the end product should show
-You would only benefit from having a carbon bottle/snake
-You would benefit greatly if you have a carbon bottle/snake AND RO/DI system.

Leading the blind. Phung keep us posted on how this works. TDS reading ect.

+1 With everything stated..

My Carbon Snake has over 100 times that amount of carbon than the RODI. It is a 2 inch flex tube that is about 15 feet long filled with pelletized carbon.

A 2.5" X 10" cartridge gives you 49 cu. in.
A 2"x 15' long tube gives you 565 cu. in. of carbon.
It's not quite 100 times.

If you want 100 times the carbon, you will need to extend your tube to 130 ft.

The expert who sells RO/ DI system says the 3 stage pre-filter is quite enough and I'll go with his opinion.

[mgarrido]

What is your TDS before the 1st stage of the ro/di and what is the water pressure after the carbon snake?
Do you have chloramines in your tap water?

I am not sure on the TDS cause I don't have a kit. Water is coming from the faucet outside before it reaches the house. I am just using it so it can help me extend the life of the RODI cartridges. Not sure if it is any better but what the heck. I have 2 huge carbon snakes that I would like to use and not just sit there doing nothing.

You have once again picked what you wanted to read from my post like "selective hearing". I said "UP TO 100x Depending on size of carbon bottle". Not everyone runs the carbon snake, there are many that run the large carbon bottles and some even 2x carbon bottles. There is like 3496 cubic inches in 2cu.ft. x's that by 2 and you have well over 100x the amount of a RO/DI filter.

AGAIN, IF YOU ARE CONTENT WITH JUST THE RO/DI AND YOU ONLY OWN AN RO/DI YOU HAVE NO REASON TO JUSTIFY A PRE-FILTER.

For me the most important to know is the water preassure going into the RO/DI unit before and after the carbon snake. With or without a prefilter if the PSI is not around 40-50 for a 75GPD unit your are doing nothing for help your RO membrane.

[eklikewhoa]

if you are running the outside faucet for your water supply I don't see how you wouldn't have the pressure. I think the problem is when you have your water line tapped like your fridge water supply.

[mgarrido]

carbon snake or any other pre-filter should be clogged by the normal use. You need a pressure meter before the RO membrane in order to know when to replace or flush it. I have been using a 3 stage prefilter system before the RO/DI unit and that is how i know when its time for replace the cartridges. I use that prefilter not only for my RO/DI unit, also for the carbon bottle line.

I don't mind your later posts as they have qualified/ amended what you said earlier.

It was the earlier sweeping statement that said adding "a carbon snake" will be 10x or 100x better than the RO/ DI pre-filter that I did not find accurate.

The 3 stages pre-filter of a good RO-DI system have already done the work. Adding more does not mean better, let alone 10x or 100x better.

You sold it like a snake oil saleman and that is not useful for the people who are not familiar with either devices.
