Algae in the tank, in corals and all over even if you don't have macro, will release carbon dioxide and take in some oxygen after the lights go out. This will lower the pH. CO2 can also be higher in the winter time and lower the pH, so it's good to have a power head moving the water to the top of the tank and creating some ripples. This and other water to air contact can help gas exchange and stabilize this.]]> Mon, 15 Nov 2010 00:20:58 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=44722&PID=385308&title=ph-lowest-and-highest#385308 http://www.utahreefs.com/forum/forum_posts.asp?TID=44722&PID=385303&title=ph-lowest-and-highest#385303 Author: SGH360

Yup its because of Gas exchange. Thats all i know]]> Mon, 15 Nov 2010 00:01:32 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=44722&PID=385303&title=ph-lowest-and-highest#385303 http://www.utahreefs.com/forum/forum_posts.asp?TID=44722&PID=385299&title=ph-lowest-and-highest#385299 Author: davser

is it true that the ph changes depending on the time of the day?]]> Sun, 14 Nov 2010 23:53:55 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=44722&PID=385299&title=ph-lowest-and-highest#385299
