My pH dropped.... - Page 2 - Aquarium Advice

The air tube on the powerhead isn't doing anything. It can't hurt, but it doesn't oxygenate the water like in a freshwater tank. In saltwater, the oxygen exchange happens at the surface. That's why you want surface ripple, and why you want to stay away from deep, odd shaped tanks (less surface area per water volume for gas exchange.)

I've read lot of other stories from folks that experience pH drop right after summer is over and close up all the windows that'd been open all summer. It surprised me when I read about it, but it obviously has an effect.

Glad it worked out, but keep an eye on it to make sure that the solution was really the solution!
