So, as I understand it, R/O units do not remove chlorine. Since my water source does have chlorine, I typically have to age it. I have a 75gal rubbermaid as my reservoir right now. I really want to do a continuous drip system, and this device looks like it may work. Has anyone used this or something similar as an inline dechlorinator?

I've been reading about the copper/zinc being bad, but what if this unit were in front of an r/o unit? Would the r/o remove the zinc/copper?
 
Just an inline dechlorinator, if your handy you may be able to make one from parts.

If I used this I would drip it into an aging tank. Spec is 85%-90% and that's probably when the filter is new.

A drip system is usually between 2-4 gallons an hour / 1400g-2800g mo. / 17500g-35000g yr. so filter changes are probably 1-2 times a year. Other people on here with very large tanks drip directly into the tank w/o dechloring (I'm still debating that one) and they haven't seen any degradation of their fish.

R/O systems usually have a carbon filter to remove chlorine, hydrogen sulfide and organic chemicals (fuels and solvents believe it or not) to keep from damaging the membrane. And R/O sysems produce any where from 2-10g of water a day.

How big of a tank have you got?

What kind of fish?

Any pix?

Yeah, I was wondering about capacity too. It does say it processes 4-5 gallons per minute, or 240gph. My thoughts were to use a literal overflow since the tank is to be built and I can build this into the design.

I only want it to process around 65 gallons a day. I wanted to replace the aged water tank because of the size it needs to be. For a 1000 gal tank, I need a 250 gal reservoir that would be drained and refilled 2x a week.

If I put an in line filtration/dechlorinator in and throttle it to supply 65 gpd injected in the bottom of the tank, the literal overflow would dump the old out the top, and I could eliminate the 250 gal reservoir. I'd be basically exchanging 25% 2x a week or every 4 days, but it would be a constant exchange vs scheduled total 25% changes. Plus it would be fully automated that way.

I was looking at this R/O, but it doesn't say anything about removing chlorine. Can anyone point me to a system that does remove chlorine in line?

I think, while commendable that you're thinking about it, you're too cautious. The R/O part of the system doesn't remove chlorine but the carbon and particulate pre-filters probably do. You could add another prefilter to the front of the unit you decide to purchase and possibly get more use from the R/O unit.

In today's litigistic society no one wants to state that their product WILL do something. They usually only state that it SHOULD do it. The truth is... it depends on several things:
1. the quality of your tapwater, day-to-day
2. the quality of the activated carbon in the system
3. the AGE of the carbon in the system
4. the flow rate

To know what's happening, you'll need to test periodically.

Hope this helps. Dan

Ok, I understand about the space probs now, just my way of doing things. If you have hardy fish, the aging tank could be eliminated.

Injecting the f/w at the bottom could cause problems from the pressure if your actually drilling the bottom of the tank. Running a pipe from the top of the tank to the bottom and letting the f/w flow into it is probably the best idea.

It's not actually going to be a true 25% W/C either 'cause your mixing old and new. There was a very GOOD & LONG thread on this with all sorts of math that we thought we'd never use, and I am definitely not going to try and repeat it hear :D .

Home depot / lowes have chlorine cartridge filters, and r/o units too.

I'm searching but having probs too...maybe rallysman remembers it?
 
I think I found it. It was between you (dr joe) rallysman and someone else. I just read the whole thing. GOod stuff. I've got a call in to the chemist at the water authority, as I've never tested my water for chlorine vs chloramine. Just always treated a res for both. Now that I want to move away from the chemical treatment, it matters.

I found a chloramine filter. The interesting thing I've found is that you can buy the inline housings and put whatever filter media in you want. You could do a 3 stage filter with 1 stage prefilter, 2 stages for chlorine/chloramine all with the parts. The housings arent' that much, but the chloramine filters are fairly steap, but should last a while.

Here's where I was looking.

Those are good prices (check shipping), very simular to HD or lowes just that their stuff isn't online.

You can also get filters for heavy metals.

Should last 2-3 months as a drip system.
