November 13, 200718 yr Author comment_194717 if it only makes the ph higher. how long does it take to get it down to a ph oif 7.theres no other worrys then for the fish, cheers ant Report
November 14, 200718 yr comment_194783 Im not sure if it will come down... Maybe it would after a few weeks underwater with lots of water changes? I did look into this a while back for an african tank but then again I WANTED it to make the ph higher. So didn't really research trying to make it go back down to 7. Sorry I can't help more maybe someone else has done this and knows some tricks? Report
November 14, 200718 yr comment_194916 It might drop after about 2 decades... if you are lucky! Basically as long as there is lime (which is a big component of the concrete) in the tank, the pH will be very high. If you want a neutral pH you will HAVE to seal it... Report

January 10, 200818 yr comment_206268 I'd be as concerned about what was leaching into the water, I'm sure some amounts of lime and what not would be acceptable but who knows whats in commercial ccrete. Report
