The waste water that is "rejected" by the RO membrane (doesn't go through) goes down the drain as waste water. Some people save/collect it to water yards or for other purposes, but most don't.

Diana I used RO for a while.
Ran the RO into several garbage cans then topped off with tap water.
The garbage cans were on wheels, so moving them around the house was not a problem.
Rubbermaid Brute, and I have the 32 gallon and the 44 gallon sizes. Easier to move when half full, then I use a garden hose connected to a shower to top them off when they are in the room with the tanks.

When the RO unit died (it was very old) I gave up. My tap water is fairly soft, but the Rams wanted the RO before they would breed. Cardinal Tetras prefer the softer water, too.

One of my customers kept sea horses and used a portable RO unit to start making the water for them. He had several tanks with breeding pairs.

If you already have established tanks, you do not want to change the water completely to the remineralized RO water all at once anyways. You need to do gradually to avoid shocking the fish and plants. Just remember that you need to remineralize RO water by adding some tap water back into it, or by using something like GH Booster from GLA, and adding Baking Soda to raise your KH.

www.bulkreefsupply.com is a great place to purchase RO units. You can buy one of their stock items or design it yourself. Ships within 24 hours. Great customer service as well.
Thought they were more expensive than that, saw one for 129.00 not bad.

How do you "store" your water?

I've bought it from vending machines usually found in front of grocery stores. Be sure to check the maintenance log and inspection sticker. If it doesn't have one look for another. It costs $1.50 for 5 gallons here.

sarahspins You can usually buy it at your LFS.. or you can set up your own filter. They're not that expensive or difficult to install.

Mahlady Can't do RO I have 2 55gs and a 30g

Purigen keeps it clear, very
Fish are doing well.
Plants are just "there" with little or no growth

sarahspins My water isn't quite that bad, but I routinely measure my tap at 17˚KH and 20-22˚GH

I always laugh a bit to myself when I see someone describe their 6-7˚ GH water as "hard"

RO water is your friend

Wow, never knew anyone who kept milk of magnesia on tap.

Doesn't it make seeing the fish a little difficult?

Hey, that sounds just like my water! I hate it, I'm always dumping vinegar on everything to keep the limescale at bay. Our landlord won't let us put in a water softener, for whatever convoluted reason.

I use R/O water. A lot of R/O water.

Mahlady I don't know. The chart stops at 12 drops, I used the API KH/GH tester.

It took 26 drops on the KH and 29 for the GH.

What are the units of measurement? Parts per million? It does not make sense if your measurements are in German degrees.
02-19-2013 02:15 AM
UDGags ummmm.....How did you measure those numbers?
02-19-2013 02:10 AM
Zorfox WOW! The good news is you could probably bottle it as a GH booster
