I was just wondering if anyone had any suggestions on a test kit for me. My local store has one made by Red Sea, and the other is by API. Either one better then the other...?
Also, I got a powerhead and was wondering where I should place it...? Should it be in the back blowing toward the live rock, and how high or low should it be in the water? One other question is the powerhead came with an air tube and air valve for oxygenation, but the only way for it to work is for the air valve to stick out of the tank, so this means I can't put the unit very low in the water if I want to use this method. It did come with a plug if I don't want this method in which case I could put it as low as I wanted in the tank. Hope that makes sense, so which method should I use...? Any help and suggestions are much appreciated, thanks!
