awwww mefilter has broken for sum reason. I washed it and then plugged it back in and now nothing happens. Its new and cost me like forty pound but i dont have a reciept. any ideas?
Is it an external filter?
Did you turn it on without water being in it?
Check that the impellor (spinny propellor thing inside) is free and can spin using your fingers without the filter being plugged in. Then prime it with water as per your instructions and try again. If there is no noise from the impellor part at all it's either a blown fuse in the plug, a faulty plug socket or a dead filter. Hopefully not the latter.
ps Bacteria will be dying off quickly while your filter is off. You need to get all your old media into a new filter asap to avoid an ammonia spike if you filter is dead.
