RO water

I'll be watching this.

We are metered for our water and will be paying for that waste when we go marine...
 
alot of people use it for watering the garden
 
Its actually safe to use for freshwater fish. I used to run the waste on mine 30 feet under the lawn and into the pond. It kept the pond topped up and give it a constant water change.

Smithrc, since the ratio of clean water to waste water is about 5:1, the waste water will only have contaminants at concentrations of about 1.2 time greater than the input water.
 
and with the phosphates in the pond being probably higher than the tap, it will do more good than bad. if using it fror an aquarium, then you could use the money you save on the dechlorinator to but a phosphate remover such as rowaphos or antiphos.

ah - but surely everything in the original water will be 20% higher (or less i suppose if you have a cheaper RO unit that gives 1:7 ratio)

so the chlorine and cloramine will still be in the waste water.

does the water come out in a trickle from the waste? or could it go via a hose into a raised tank?
 
I use the waste water to fill up the washing machine. I thought about using it in my FW tank, but read too many horror stories about this. I don't want to subject my FW fish to high TDS levels, just too risky.

No, the chlorine/chloramine and physical particles and so on are all removed by the sediment and carbon filters before the membrane, as these would damage it. the only things that get to the maebrane are things like phosphates, nitrates, and a number of other chemicals which I'm not to sure on so I won't bother trying to name any :D . so the waste (after the sediment/carbon filters) will be free of a lot of things but like you say, will have higher nitrates, phosphates etc.

BUT

say your tap water had nitrates of 5 before the RO, it would only be 6.25 after so not a big increase. I wouldn't recamend it for rays, discus etc but for a general community tank, then I don't see a problem.

We'll have to get a large butt in the garden then i think - and use it for the tropicals

Thats assuming the Planned tank goes ahead as planned and Lorna dons't push for the tropical instead.
 
A water butt :D :lol:
