chuckfullservice Posted April 9, 2008 Share Posted April 9, 2008 I have been experimenting with topping off with tap water for a couple of months now with no I'll effects. My algae has actually decreased! All corals and fish seem fine . I read in this post that they add polyphosphates! 15ppm I think. http://www.chiefengineer.org/content/conte...content/790.htm Just wondering because I'm going to experiment with tap water over ro/di ! I figured since I have not seen any problems in doing top offs this way , I should be ok! I know it's not recomended but like I said it's an experiment! Please no comments just use ro/di if I notice any changes in my system I will emediately go back to r/o which is what I was using before! Link to comment
BKtomodachi Posted April 9, 2008 Share Posted April 9, 2008 I don't get the point of this post. Your tap water contains phosphates, algae thrives on phosphates. You will likely see an increase in phosphates over time. Am I missing something? Link to comment
chuckfullservice Posted April 9, 2008 Author Share Posted April 9, 2008 It says polyphosphates! Are they the same as Phosphates? Link to comment
BKtomodachi Posted April 9, 2008 Share Posted April 9, 2008 AFAIK They are just polymers of phosphate groups. I would assume they would decompose easily into the monomer units, but I suppose I could be wrong. Any chemists in the hizzouse? Link to comment
TheUnfocusedOne Posted April 9, 2008 Share Posted April 9, 2008 me me me! im agreeing, it could be polyphosphates from the decomposition of organic materials phosphate is everywhere in organisms, and is actually where most organisms get thier energy ever heard of ATP? Adenosine Triphosphate i wouldnt worry bout it non its deff not harmful unless of course you protenate it n make it into phosphoric acid, not recomended itll just make algae grow Link to comment
chuckfullservice Posted April 9, 2008 Author Share Posted April 9, 2008 I found this and thanks for the lesson! http://www.arvanitakis.com/en/c/Corr_cwt/polyphosphates.htm Truth be told I don't have a algae problem so the 15ppm probably gets diluted over the course of 40 miles of piping . I beleive it states it bonds to the minerals in the piping. Thus probably minimizing the actual ppm. to less the 15ppm I have test my tank water and my readings are 0ppm phosphate. I never really thought to test it right from the tap though? That probably would have been a smart thing to do ? I never said I was smart just cute! Link to comment
