RODI filter

[Legal Reefer]

Anyone know of an inexpensive RODI filter that will remove chloramine and amonia? I usually get my RODI water from Wal-Mart, but am worried that their filtration system might not remove chloramine or ammonia.

The most reasonable will probably be bulk reef supply. I wouldn't use the water from those refill stations. They all to often do not make the quality of water required for reef tanks and will often lead to nuisance algae.

I didn't know you could buy RODI from Walmart? If you're referring to the refill stations people use for drinking water that is not RODI, It's just RO water, and I'll second the BRS filters or Spectrapure which is what I own. I would suggest an upgraded system with dual RO filters to up production and save you on waste.

Exactly what I'm going through now. Going to a not so local fish store tomorrow that has good water at .50 per gallon.

Thanks for that information, very helpful.

You're welcome, also if you are going to purchase your own system go on your municipalities website and check whether or not they have chlorine or chloramine in your water. There are different filters required to handle chloramines than regular chlorine. At the end of the day the upfront costs of these systems seem daunting but over the long term they pay for themselves in very little time.

Thanks, did that last night and found that they do use chloramine.

A second membrane will reduce your water usage but will increase your resin usage. There are a number of variables that have to be considered to calculate if it is better or not. I would recommend contacting one of the companies like Buckeye Hydro, Spectrapure or Air Water and Ice.

I use spectrapure, I suggest you just buy one of those or from Bulk Reef Supply. No one wants to have to run to walmart to get water for an emergency.

They are also really easy to setup, mines hooked up to my washing machine. You can hook them up anywhere if the adapter fits and theres somewhere for the waste water to drain.

The time you save by making your own water is worth the investment alone.

I'll second this, forgot to mention these things to consider as well. TDS levels are a big factor in whether or not it's worth it to run dual RO filters. BRS did an investigation into this and I believe when your TDS is above 400 it's not as worth it. And yes running 2 will consume your DI at least if not more than twice as fast because of the slightly higher TDS you put through it, also your putting twice the volume of water through it. So a few things to consider before purchasing your system but nothing major.
