Chloromines (1 Viewer)

[Reefaddict79]

While diggin through some old mail stacked up in the wifes office I came across a letter from our water company stating that they will be switching to chloromines which I guess explains why I am blowing through DI resin and have some funk poping up in my tank. Soooooo I guess this is just a little heads up for people in the 77449 area.

Anybody have any recomendations for a RO/DI unit setup for removing chloromines?

i have the aquafx mako with dual chloramine blasters.

 

[Reefaddict79]

that would look cool in my garage, It looks like it could put fires out. I guess it has a filmtec membrane and all that. What allows it to remove the chloramine? Is it a special carbon?

 

[AquaNerd]

yeah, it's a special type of carbon that removes the chloramines.

GAC or granulated activated carbon will remove chloromines. Contact Russ @ Buckeye...he will hook you up with what you need. There are add-ons you can purchsae for an existing RO setup.

I received a letter from my water company yesterday that they are switching from chlorine to chloramine now. They did have a warning section in the letter for people w/ fish tanks that this chemical is harmful for fish tanks and the users should add some charcoal filter or some special filter to remove the chloramines... I guess some reefkeepers may have complained to the water companies
I guess I have to go back using DI water again now which I have stopped for almost 2 years! or maybe adding some extra chambers w/ granulated carbon..

 

[AquaNerd]

quoc, just get the chloramine blasters from aquafx. they do great. i'm sure you could buy them as an add-on.

He has a chlorimine filter thats pretty cheap. goes before your ro membrane. Chlorimines are supposed to be hard on your mrmbrane.

yeah i think i'll get one or two of those chloromine filters as add-ons - much cheaper option than DI resin which cost more money and labor..

So you currently do not use DI?

Hi, Reefaddict.

See here for Russ's comments about chloramines.

I'm not using my RODI until I get a GAC installed. I'm using the windmill water for top off and water changes instead. I'll probably order a GAC filter this week.

good luck,
Steve

I purchased a RO/DI unit from bulk reef some time ago. They have chloromine add ons for cheap to.

 

[reefgnome]

so, will the chloramine show up on a TDS tester? If it does not and if it is so critical to remove it completely, how can we assure timely replacement of the GAC/carbon block?

No stop using DI for 2 yrs now. My tap water TDS is ~300-400ppm, after the RO membrane is ~30-40 PPM, so the DI resin expired so quickly - cost lot of money and effort to replace them. So I decided to yank the DI chamber out and live w/ a 30-40ppm water and didn't see a noticeable change in algea issue, so i'm happy w/ that though some people would consider my RO water is too dirty But maybe that's why my corals grow so fast

 

[Reefaddict79]

I dont know if chloromine will show up on TDS, I do know that before I would go through a DI cartridge in about 100 gallons . Now I have made +- 300 gallons and barely an inch into the DI resin

Carbon prefilters will split the chloramine back into chlorine and ammonia. The carbon will adsorb the chlorine, but most of the ammonia makes it through the membrane and is caught by the DI resin.

The key thing with chloramines is the provide for adequate contact time with the carbon. A single, high qaulity carbon block may be sufficient when new, but a second carbon stage is a good idea, especially as the carbon function decreases over time.

Plain old GAC really has no place in the types of systems we use in this hobby.

I just purchased the add-on from Russ at Buckeye. He is great to deal with and very responsive.

Thats why I reccomend him to everyone. Competitive price, exceptional service. I have even emailed him on the weekend & got immediate response.

 

[Kyle]

Yes, I was calling him on Fridayevening and even Sunday and he had no problem talking to me and answering questions.
