Im starting this thread in response to all the waste water interests I have seen popping up lately on RC. Im sure plenty of people on this forum already use a similar DI resin system like mine, but I just wanted to point it out to all the RO users out there- that there is a better more efficient way to get good clean water for your reef tank without all the time and waste water that comes with using RO filters
Wana go green? get rid of your RO and double up your DI, the little bit of extra money you have to pay for replacing your DI more often is worth all the hassle and makes up for your water bill anyways. Also since your using more DI resin you can buy bulk and save even more money. I usually buy a big enough bag of DIresin for at least 7 refills and this lasts me awhile and makes allot of good water. I don't have to worry about waste water because I never have any. Also for those looking to really save money some DI resins can be reused but I have never done this personally.
I don't understand why people waste there time, water, and money with RO filters. Especially the people with large tanks, must take forever to make enough water for a single water change let alone the constant need to top off, and the hassle of worrying with the waste water. Whats the average waste water ratio using an RO filter 4 to 1- that is ridiculous and pricey for your water and or sewage bill.
This is what I did, I modified my 2 rodi filter systems into an effective prefilter system before my dual DI filter, this setup works great for me. I took out the ro filters and replaced them with inline sediment filters for added prefiltration. The best part is I get zero waste water and zero ppm as long as I keep the filters clean and replace/rotate them on time and in the correct order. The water passes through 8 filters ( sediments,carbon blocks, Gac's, inline sediment's) before even entering my dual Di filter. I can make 200 + gallons of 0 ppm water in like a half hour lol
The best tip I can give for a setup like this is to get two units so you can alternate them when you change out your filters- always using the dirty unit first and then let the water travel through the second cleaner unit containing the fresher filters. This way you have a very efficient prefilter that can be rotated to get the most life out of your filters . SO you get water with a very low ppm before the dual DI and then you don't burn through the DI resin as quickly. Also rotate the dual DIresin filters in the same order so you can use the DI resin until its completely exhausted saving you money. A tds meter with two probes is awesome for a setup like this, it helps you know when its time to change and rotate the prefilters, and the DI resin giving you a maximum yield of good clean water for your fish and coral.
I store my water in large containers and I run a Uv sterilizer in these storage tanks to prevent mold this keeps my water clean, and fresh. This is one of the best times to use a Uv filter imo. It doesn't take much time at all for me to fill up both my 100 gallon storage tanks. I then treat the water with prime just to be safe before adding the water to my tanks.
Hope this helps somebody out, maybe I should draw up a diagram or something . What do you guys and gals think about going green with a DI system?
