I want to put a water pump on a horse trough with the pump on the outside of the fence. There is a hose attachement at the bottom of the trough for the intake. I want to have the outake hook back to fall into the top of the water, reducing algae and eliminating mosquito larvae. I have never used a pump before. Need advice on type, size, etc. Thanks!
Some people put goldfish in their troughs; I don't know if this is a great life for the goldfish but it would be easier.
A 12 volt water feature pump from a garden center would do the job. Four litres a minute with a shower head on the end going into the trough should give the aeration you need. The head off a plastic watering can would also do.
