I have come to the conclusion that there is not enough information available in one place regarding using RO/DI water in freshwater tanks.
Things I am interested in knowing:
- What system is necessary? Do I need RO/DI or is just RO enough? How about a decent quality drinking water filter with more like 5 gallons per minute flow rather than 75 gallons per day for the RO/DI? Does a drinking water filter account for hardness, pH, chlorine, chloramines?
RO is all I use no DI unit here. Either will work depends on your needs. A drinking water filter is just a carbon filter and will not remove chloramines. A drinking water filter will only remove chlorine if hte flo of water is slow enough across the filter. RO Units use several methods of filtering the water from a Micron cartidge to trap sediments, carbon to remove impurities, Membranes to fitler 99% of everything out of hte water. If you add a DI unit the water will be nearly empty of 100% of everything but water. My RO unit takes my water from a TDS of 123 down to a TDS of 1, I could get it to zero if I saw the need for a DI unit. I store ~50g of water to age it before my use. I also still add a capful of Prime even though I don't need it I have it around and use it.
- How do you have your system set up? Permanently plumbed into your water supply and a drain? How does it shut off when your storage tank or bucket is full? Float valve? Auto shut off?
Mine is hooked up into the master bathroom sink, I turn a couple of shut offs and turn the sink on and it is pumped to the storage tank in the next room, I jsut manually turn it off and on as it doesn't take much watching
- What are you mixing back into your RO water to buffer it? Is there a way to standardize this without using a text kit every time?
You may need to test the first few times but will eventually figure out what you need to add each time, mostly trial and error. I use GH Booster and Baking Soda to reconstute my RO.
I have done quite a bit of basic research, but I would appreciate some more insight before a purchase an expensive unit. I do not want to find out that it is too difficult to use after I've already spent around $200.
Sorry for the huge list of questions, but any that you can advise on would be greatly appreciated. Thanks.
Lots of options and opinions if you go for it it does cost upfront but its a choice not a requirment 99.9% of the time.
