victoly Posted March 13, 2013 Share Posted March 13, 2013 Weirdest thing happening in my tank right now.I noticed high pH in my tank last night (8.5+). Today it was very cloudy. Also there is a red film over my tubing, in my filter sponge and on my mp10. It also looks like about half of the volume of my GFO reactor is gone. My alk is also low again (115 ppm). I'm not freaking out yet, as everything looks relatively happy (sps included).I think it might also be because I upped my kalk dose in addition to the vinegar I dose in the kalk.I think it's a bacterial bloom, but I can't explain the GFO film everywhere.

+Capt. Obvious Posted March 13, 2013 Share Posted March 13, 2013 Too much gfo (or any carbon source) can lead to ph spike as to where the gfo went...good question Quote Link to comment Share on other sites More sharing options...
victoly Posted March 13, 2013 Author Share Posted March 13, 2013 GFO isn't a carbon source though ... Quote Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted March 13, 2013 Share Posted March 13, 2013 Vinegar is Quote Link to comment Share on other sites More sharing options...
victoly Posted March 13, 2013 Author Share Posted March 13, 2013 Right right, that was my presumption. Either that or supersaturation from the kalk. I was mostly curious if anyone had the same thing happen with gfo. Quote Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted March 13, 2013 Share Posted March 13, 2013 It could be that your alk and ca were so high that you were causing precipitation upon introducing more ca and alk, as for the case of the disappearing GFO...my bet is on old man Whithers who runs the carnival...I am sure the members of Mystery Inc. can solve this caper.

George Monnat Jr Posted March 13, 2013 Share Posted March 13, 2013 What brand and how old was the GFO? Quote Link to comment Share on other sites More sharing options...
victoly Posted March 13, 2013 Author Share Posted March 13, 2013 Phosban. A little over a month. I've got an alternate theory that ill post when I have a keyboard. Quote Link to comment Share on other sites More sharing options...
Peter Gott Posted March 13, 2013 Share Posted March 13, 2013 I'm pretty curious to hear this alternate theory... Quote Link to comment Share on other sites More sharing options...
victoly Posted March 13, 2013 Author Share Posted March 13, 2013 Ok, so, my reactors are set up in parrallel. I believe that asmy other reactor of purigen/GAC became clogged, that it increased flow to the GFO. Over time, it reached a threshold where it just physically pulverized itself and leaked out. The timing with the high pH/alk drop may not be causative. Quote Link to comment Share on other sites More sharing options...
Peter Gott Posted March 15, 2013 Share Posted March 15, 2013 Ok, I'll buy that. Do you think it caused the cloudiness and the film? Quote Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted March 15, 2013 Share Posted March 15, 2013 Ok, I'll buy that. Do you think it caused the cloudiness and the film? cloudiness/film most likely is bacteria bloom and his theory would support that I'd say Quote Link to comment Share on other sites More sharing options...
