The circulation pump on my Fluval Spec V 5 gallon quit working. I bought the tank only three months ago. Any thoughts on why it conked out in such a short time?


did it "conk" out or is the pump impeller stopped by a buildup of material ?? the reason I say this its very unusual for a aquarium pump to go completely out (ive had one running 24/7 for ten years) but in that ten years ive replaced two impellors and cleaned it out over one hundred times , and yes three months is the perfect time period for a cleaning needed !!!

How to fix fluval led


on this tank the lights are built into the filter pump housing , if they go bad it might be possible to retrofit a new sealed light bar into the same space , but you will need to have previous knowledge of electronics and specify L.E.D. lights as they don't work like regular light bulbs but require a special kind of power or will be damaged if hooked to wrong type of power I suppose its possible to use batterys but id have no idea how long that would work
