wifesaidgetahobby Posted February 11, 2016 Share Posted February 11, 2016 So my question is this, is it possible to have a zero tds on a 5 stage Rodi system and still cause an algae problem? I ask this because I was told that when the tds starts to go up it is time to change your filters. I have had an off and on algae problem in my 90 gallon tank mostly seen the algae after a water change. In November of last year we had a wind storm in Spokane, Washington which took out our power for 2 weeks in 14 degree weather, well as you can imagine we lost the tank. In December we moved to Boise, Idaho and when I was taking down the Rodi unit I noticed the line from membrane to the ionize cartridge had algae buildup. I believed I had a bad tds meter but when I installed it on a friends 1 month old system the readings were zero, watched the meter go from 174 to zero. The filters in the Rodi unit are about a year old. Water in Spokane is roughly 175 tds out of the tap. Quote Link to comment Share on other sites More sharing options...
Exodus Posted February 12, 2016 Share Posted February 12, 2016 Yes it is possible, your assuming your Algae is caused only by Silicates, when in Fact it can feed off of light and phosphates as well. If your TDS is 0 and you have verified this, I would start looking elsewhere for the source. Quote Link to comment Share on other sites More sharing options...
