got a new pump ( mag drive 9.5) and saw where one site said "not recommended for external use". what say you the jury? replacing a rio 3100 and want to eliminate the shock factor by having the pump sumerged.
next question when i put 192 watts of light on the ole 55, i also read that running my uv light will kill algae spores. i have some algae eating fish and want to grow algae, the right kind of course, please help with my confusion here. <img src="graemlins//confused.gif" border="0" alt="[confused]" /> :)
