SRC Member IshDeOne Posted March 18, 2015 SRC Member Share Posted March 18, 2015 Hi Reefing bros, Currently I'm looking to set up my reef tank again. Learnt quite a number if valuable lessons from my first setup. I'm looking into having a chiller n a RODI system as well. Possible tank size :3ft by 2ft by 1.5ft Approx: 60 gallons Mixed reef How much does it add to ur water n electricity bills by running such a system? I read tat 1 gallon of pure water = 4 gallons of waste water.. Any way to reduce tat? Wat do y'all do wit the waste water? Any cost efficient ways? Thanks in advance. Still a newbie bros.

It depends on the water pressure. Otherwise a booster pump would be a good addition. Visit madpetz he will be able to give U very good advice. Ask him about a upgrade of the ro membrane too for faster collection of rodi water. I upgraded mine to 200g/day if I remember correctly Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
SRC Member IshDeOne Posted March 18, 2015 Author SRC Member Share Posted March 18, 2015 In turn of cost of running a chiller? Is the additional bill cost alot? Like 100 dollars extra? Or cheaper? Quote Link to comment Share on other sites More sharing options...
SRC Member asg Posted March 18, 2015 SRC Member Share Posted March 18, 2015 Why not just use DI instead of RODI? Tds can be zero too Quote 子非鱼,焉知鱼之乐... (you are not the fish so you...)

Land2013 Posted March 18, 2015 Share Posted March 18, 2015 I have about 55gal and abt $50 for electrical but need to use cost saving equipment like led light, dc pump and so. If you dont want to have waste water, u could use di only if ur water change volume is not so much. Di exhaust faster than ro but no waste water.

SRC Member IshDeOne Posted March 18, 2015 Author SRC Member Share Posted March 18, 2015 Really? I didnt noe abt using Di water.. Any idea wats the difference in beneifts/cons Btwn tat two ttypes? Thanks alot for helping out guys. Quote Link to comment Share on other sites More sharing options...
Land2013 Posted March 18, 2015 Share Posted March 18, 2015 Different is just with ro. U still can get tds 0 with just di resin plus normal filter n carbon. Quote Link to comment Share on other sites More sharing options...
Land2013 Posted March 18, 2015 Share Posted March 18, 2015 Should be without ro. Quote Link to comment Share on other sites More sharing options...

SRC Member illumnae Posted May 5, 2015 SRC Member Share Posted May 5, 2015 Difference between RO and DI is upfront cost + cost of water vs cost of resin. Using DI only, your resin exhausts much quicker since you need to reduce tap water from about 60-90 TDS (water from tap usually about this level) to 0. Using RO + DI, your resin lasts much longer since you only need to reduce RO water from about 6-9 TDS (RO usually reduces about 90% TDS on average) to 0. However, RO + DI involves waste water and higher upfront cost. Hence, depending on the size of your tank and the frequency at which you change water, one of them would prove more cost efficient for you - you'll need to calculate for yourself and decide.
