HUGE SCARE TONIGHT!!! I fed my corals adn others. I turned off the main filtration powerhead to do so. When I turned it back on, it did not do a damn thing. For the following twenty minutes I was scrambling with a flashlight between my chin and shoulder trying to get it to work, checking all connections, the power supply, occasionally getting shocked from any dripping water going down the power cord. that is what told me it must be the ph, and not the power. So I ran the tank on my chiller pump for a while by flowing the outtake directly into the tank for a while, then all of a sudden, the main powerhead turned back on, causing the intake eductor to disconnect from the ph. Now I was REALLY getting shocked as water went everywhere but IN> Problem solved, and the power no longer shocking anything, but WOW, I thought I was going to lose everything before any store opened for me to buy to another ph. STUPID F@#%$#@ ^#%&^$@ JBJ. I think I am going to buy a replacement ph just for the future just in case. ANY OTHER SUGGESTIONS?
