SRC Member ervine Posted August 10, 2006 SRC Member Share Posted August 10, 2006 I started to use DI water for my water changes and top ups since 2 weeks ago... so far not much noticable difference but it's too early to tell I suppose...

SRC Member patrick123 Posted August 10, 2006 Author SRC Member Share Posted August 10, 2006 After using RO/DI, no regrets. Should have started with it all along. My waste water goes into the koi pond. So no waste water at all. Quote Link to comment Share on other sites More sharing options...

SRC Member MadScientist Posted April 20, 2008 SRC Member Share Posted April 20, 2008 use evian water! makes ur fish feels like its living in french alps! anyway if i m not wrong, ro/di water has a lower pH than 7. cos due to the increased dissolved co2. with the removal of minerals, the buffering capacity of the water is reduced too.

ocicato Posted July 28, 2008 Share Posted July 28, 2008 RO water produces super pure water but the RO device is damn expensive to maintain. DI water, from what I've heard, is devoided of heavy ions and nutrients. The water will actually try to balance itself out by absorbing depleted ions and nutrients from the surroundings or living tissues. Thus, it'll be best to treat the DI water with trace elements before adding into the tank. Quote Link to comment Share on other sites More sharing options...

oceanus Posted September 22, 2008 Share Posted September 22, 2008 i dont think this is really necessary... if you control you PO4 level well with a FR and other alternative like Chaeto..you shoud not have any problem with algea problem..

I am not a chemist but i once heard a colleague mentioned that you cant drink DI (de-ionised) water as it will extract "calcium" from your bones. Not good for health. So i think it applies for our corals too.. You need to treat it before adding to tank. Probably the calcium in the tank will balance the side-effects..

SamuelTan Posted November 26, 2010 Share Posted November 26, 2010 Hi I have a few question about DI unit! It uses Resins to charge up right? How long does it last? Quote Link to comment Share on other sites More sharing options...
SRC Member tunicate Posted March 24, 2011 SRC Member Share Posted March 24, 2011 Depends on the amount if DI resin & usage. A TDS meter will help you decide when your media is exhausted. Quote Link to comment Share on other sites More sharing options...

sherman Posted March 26, 2011 Share Posted March 26, 2011 What test kit you use to measure your PO4 and NO3? I get near 0 reading for my PO4 3 months ago. But still have red slime. Get another test kit (Same brand) still the same near 0 reading. Then one day a nice reefer help me to measure my PO4 with his Hanna PO4 tester and the reading was so high. 0.48 So be very careful the reliability of the test kit you use.

SRC Member tropic Posted April 5, 2011 SRC Member Share Posted April 5, 2011 In think some Most Colour test kit need a sharp eye to actually differentiate the Colour as some Colour is neither here nor there according to chart. Quote Link to comment Share on other sites More sharing options...
