Hey everyone, Yesterday when I was changing the water in my 26g planted freshwater tank, I unplugged my Hagen 70, so I could swish out the sponge and rinse off stuff. I got everything cleaned up, in the old water and drained then put back on the aquarium but it wouldn't start back up. After messing with it for over an hour, and getting the old filter out and running as a back up, I had given up with it. I decide it was less than 2mos old I'd take it back. For whatever reason I pulled off the motor to see if the propeller was frozen, it wasn't, but when I plugged just that in, it worked. Go figure. So I put it all back together and it worked. BUT what the heck happened?? And now I'm wondering as I was looking at other filters, if I changed this one, what is the better one to go to? Do I spned the money for a canister? Which one would be better? I do have a big bioload, I do water changes twice weekly and keep Nitrates below 40, I carefully vacuum around all the plants, to help keep things as clean as possible. Everywhere I read about filters it seems like each plalce recommends something different. So what do I do??
