Ro Water

[BigC]

I have access to a very large commercial RO system at work of which I plan to transport water home on a regular basis to perform partial water changes. My question is what sort of frequency should I perform these, once a week or twice (70ltr tank).
Thanks in advance

Change 7-14 litres every week

Do you get it free?

Do you get it free?

YES!!!!
I was going to buy a RO kit but we are on water meters and the RO kit wastes more than it makes therefore making it an unviable proposition.
So when the double glazing factory where I work installed this monster RO system and collossal holding tank then the dark clouds dissapeared so to speak. Now I can keep a marine tank. Well NANO atleast.

Well I have been keeping, breeding and showing fish for over 25 years now and have injected a lot of money into the hands of aquarst shops and dealers sometimes wisely sometimes not so wise. So at the end of the day I think I deserve a freebie every once in a while.
I was always interested in the saltwater side of the hobby but was put off by the prices so I'm going to try my hand at a Nano reef type to begin with and who knows where that will lead. (Not another confrontation with er indoors)

Way to go Big C By doing this you have already given your future nano tank the best shot at having minimal problems. No matter how much advice is given on using RO vs. tap, there are always newcomers who don't believe it or try and cut corners with tap water. When cyano or hair algae comes, then it is regretted and too late.

You may want to ensure that your company's water is OK tho'. Don't laugh but there are various types of membranes out there. A TDS meter is worth buying especially if you own your own RO filter..they are not expensive. SH

What is a TDS meter? I too have access to free water from work, although mine is DI not RO and I do the whole transport thing. Gives me some good excersize on water changes for a 45 gallon

TDS is Total Dissolved Solids. The lower the number, the more pure the water. They are not expensive. I have a TDS meter and it was under $20 bucks off Ebay. My RO water runs 0-2ppm, pretty close to pure. Another good reason to own one is that it will let you know when your RO membrane is failing: the TDS reading will climb. It can also help locate a problem in the filter system by testing water output from different areas. SH

Oh, cool, good idea
