I was doing a water change just now. I unplugged it and after the water change I filled it with water and plugged it in...it didn't start! What should I do now??? Please need some advice...this ac70 is less than a year old!
I don't know about AC but I have a HOB filter, that if I unplug/plug in too fast it seems to stall or something. If I leave it unplugged for a few minutes and try again it will start up...
If tank is cycled it's probly not as big of a deal as you think...but you could put the whisper 40 in and try to fit in as much of the old media in as you can, as well as the whisper biomedia...you can pull it out of the frame for this. skip the filter frame for now.
I wouldn't trust doing just that. What if your power goes out while your not home and it doesn't restart.
The impeller area needs to be cleaned, I'd also clean the intake tube.
I find with ACs especially smaller ones that its best to start them back up on the low setting then move it to high. This only matters if the suction has been broken.
