Choice between Bulk Reef Supply RO/DI, Spectrapure RO/DI, or Buckeye Hydro

Wow, TDS at 110 after the prefilters? That's crazy clean.

Yeah, any PSI below 40-50 would benefit from a booster pump for sure. Good call on getting one.

I still think if your water source is using chloramines full-time, that it is the culprit. I've heard chloramines will degrade membranes very quickly.

Oh yea over the last 32 years I went from a TDS of 400+ killing water heaters when GV used only Edwards Aquifer Water to Lake water and Chlorine levels up to 4 ppm, to now Chloramines and our water source coming from who knows where and who knows how far. As this area continues to grow along with SA will have to go farther east to get new water sources running through 100's of miles of water pipe. Sorry I got off of the subject but in this area every ones water will be different, depending on the source.

Maybe it's time for this monster!

Very nice but for the cost I can buy 5 years of membranes?

In the scenario that chloramines are eating up your membranes, doesn't that mean that they are getting into your tank? DI resin doesn't scrub chloramines from my understanding and they are your last line of defense after the membrane.

I'd think you'd notice chloramines getting into your system though as it would have a pretty adverse affect on some corals.

Sorry, I'm just mentioning for point of discussion. I wasn't trying to sway you to do one thing or the other. Your process is obviously working for your scenario Alton.

Here's a cheap, easy test for anyone to see if the City water has it and if it's getting through your RO/DI system.

okay ordered it this morning, that way I can quit guessing when to change filters

Yeah, that's crazy with the amount of chloramines in your City water. You would have two criteria, TDS and chloramine level, that would dictate your filter/membrane change schedule versus most others would only be dictated by their TDS level.

Another thought is to process all your produced RO/DI water in a brute trash can first and then add a water treatment product such as Prime that removes chloramines from water before using it in your reef. We have some guys in the club from Geogetown that have to deal with chloramines in their water and that is their exact process as well.

well guys,

After long debate, I went with spectrapure. Where i Live my ppm levels are in the 600's. so my strategy will be to connect the ro/di after my softener and full house filter. I hope the ppms are low enough not to really affect my membrane, and longer life on my filters. thanks for all the feedback. Ill start a thread with my current build soon.

So you are one of the lucky ones still getting great Edwards Aquifer water? It is super hard because of all the limestone and calcium. Bad on water heaters but good to drink. Hobogoto actually ran his tank using Edwards water unfiltered. I would of not but he did.

Sorry for borrowing your thread devil dog but after testing my water with test strips I have a level of two to three in, 1 and 1 after two chloramine filters, and almost 0 after DI. So maybe I need that big filter after all? Maybe Russ will chime in
