Air Water and Ice February 24, 2009 February 24, 2009 :clap: This is a friendly reminder for you to check your reverse osmosis water systems filters and membrane. All systems should get the pre-membrane filters replaced at least annually. If you have poor water to begin with, you may need to change out more often. The membrane will last from three to five years if the filters are replaced regularly. We like our drinking water TDS (Total Dissolved Solids) to be no more than 50 parts per million while RODI water for aquariums should be ZERO TDS. You can easily check your water quality by buying our HM Digital high quality hand-held TDS meter for our everyday low price of $24.95 with FREE SHIPPING. Also, since your fish love the pure water you should too, check out our complete Under Sink RO System, now on sale for $169.95. (Only $144.95 after using the $25.00 coupon described below.)

reefhunter March 3, 2009 March 3, 2009 Question... I bought a typhoon in April. I changed the sediment and carbon filters after six months and was about to change everything as I am coming up on a year. Do I need to change the membrane after a year or can I run it longer? I noticed you said 3-5 years above but you dont mention if that is for a 55 gallon reef or a 220 gallon reef...? I am running a 220 gallon reef and make about 150 gallons a month (100 top off and 40-50 water change). Thanks!
