looks good mate,how many gallons aday does it do. mark

450 but it's not doing that at the minute, my mains water is only running at 48psi. Have got a pump coming in the post tomorrow that will boost it to 80psi. The TDS meter is handy as it measures the ppm of the input and output.

I have it running direct to the pond with no dilution at the minute to slowly get the PH down then when it's where I want it i will start diluting it with normal dechlorinated water.

Mark, I did a search and noticed you have a RO system. Is yours set up similar?

Hiya

Yes mine is dead the same but 300 gallons. i have not started to add ro water to main pond yet but am adding it to the QT at the moment. how big is you pond and whats the TDS on right now. them tds meters are great as i use the same one.

do you run di resin in the last pod.

TDS in the pond is 450 with a ph of 8.8. My tap water is around 550! That's why I decided to go for RO. After going through the system it is about 14.

What Psi is yours running at Mark? And do you get much waste water? At 48psi my volume waste is twice as much as RO water. I'm hoping this will change a bit with the booster pump.

I'm not sure what DI resin is. I have sediment then granular activated carbon then carbon block filters. Should I have a resin one as well?

JM350Z · 25-10-2011, 08:33 PM

Forgot to say, 2300 gallons.

god your pond tds is well high and even your tap tds is high. it comes out of my tap at about 380.

dont know what my psi is as i have good pressure straight away. you will always lose alot more waste water to good ro water.

you can get your tds down from 14 to 0 if you run it through di resin after it has gone through the ro membrains.

you can take out the end carbon filter and the put di resin into it. what happens is the water goes through the sediment filter then the carbon filter then into the ro membrains and then into the di resin and then to pond. you will then get tds of 0
