yeah I was thinking about getting a powerhead. my pump is getting old and about to burn out...noticed the flow has started to decline, even when I cleaned it out. I added 4 more ceramic airstones in there. What I really need to get is a new timer..the other timer is a 24/7 timer, with only 8 on/off settings, totalling 16 settings. more for a light than a pump..but when I ordered it, the guy said it did 15 min aswell...what a big lie. needed it anyways though. anyone got a link to a timer I could buy locally?
