Is there anyway you can make your turtles tank quieter?

If the pump in your turtles tank is noisy - it either needs cleaning out - or there is a fault with the pump itself. If the filter is clogged with debris - the pump motor will have to work harder to push water thought it - making it labour, and creating noise. If the pump is old, it may have worn parts which are either vibrating or rubbing against each other - causing friction.

If it just needs the filter cleaned - get into the habit of doing basic cleaning duties once a week. Wash the filter out in a little of the tanks water (NOT fresh tap water - as this will kill off the bacteria in the filter sponge !) Do a partial water change every week - to keep the turtles accumulated waste down to a minimum. Remember to clean the rocks etc when you do that.

Filter pumps don't last forever and will need the whole unit replacing periodically.
