Just use RO water if you were growing in soil id say let sit,but usually tap water ph is too high.RO water is estimated to be 5.5-6.0 and tap is 7.0+

ph is not the issue, it is what elements and how many of them that are in the water that is the issue. ph is an easily corrected issue and if your tap water is less than 200ppm it should be fine. i use straight from the tap in everything, because i dont have room to let 250gal set out to evaporate clorine.

That's correct. If tap ppm is around 200-300 I wouldn't use RO. I would try to let sit with a airstone if there was room but not realy that bad. And that wouldn't work with clorimines(sp?) and with RO you are taking everything out so you have to add extra nutes everytime.

I have a RO unit going strong and took my 600+ppm to 0 for 60 bucks.. been about year and half so I think I need some replacement cartridges soon or when ppm start to rise thats about 35 bucks.

bigbudda, if your tap is that high of a ppm i hope you are drinking the ro water also. that is terrible.

You don't have to do that, but it don't hurt nothing. You are good to go Boss.

Pour water through granulated carbon to remove chloramines/chlorine.

I don't think carbon removes cloramines. But I could be wrong.

Reducing agents (sulfites, thiosulfate, vitamin C) will knock down chloramine in a matter of hours. cn

I know you are. We use dual carbon tanks for removal. If breakthrough occurs on #1 tank we switch to #2 and continue. If breakthrough on #2 we shut down. Dual carbon tanks and we recharge them regularly with new carbon.

What do you use to test cloramine levels? The system I use for work cost 1000 so I'm not getting it to test at home. I did bring it home and tested. Im 0 but plenty of clorean. And I'm realy asking?

I don't care whats in my tapwater I use my airstones for at least 24hrs, the ph starts out at 9.0+ after using the airstones for 24hrs the ph is down to 7.0+ and when I put my nutes in its close to 6.8 to 6.5 perfect for vegging in soil, add a little ph down to get it down to 5.4 for soil and flowering, been working good for me and my soil grows

Yeah, I used to work in a mini-lab, we used a carbon filter on the tap to remove clorine. It creates a more pure white in silver halide photo printing.

Dialysis unit. We use everything from test strips post tank #1 4 x daily, meter checks AM & PM. We test at 4 points in the system every shift, 3 shifts a day. As well we send out weekly samples for tests to a standard reference lab in California. Our chloramine has to be absolutely 0 as even a hint causes hemolysis (destruction of red blood cells) and patient death. Standards allow 0.000 to 0.001 PPM chloramine. Anything greater causes havoc and switching to backup.
I just started into DWC with some units I built and our RO water is a dream. A bitch to lug 7 gallons at my age. Literally 8 PPM and the majority of that is magnesium.

Ok so it's something your not bring home ether. Lol. Knew carbon worked on cloreine but wasn't sure on cloramines. Never realy looked into it sence this water district dosnt use it. And my other place is on a well.

Ya it is.. we have a well and yes we drink bottle water and cook with the RO. I know its bad, but I wouldn't drink my tap water if it was normal 100-200 range neither.
