The next thing you need to do is drain your swimming pool until there is only around one foot of water left in the pool. You then need to go about filling up a five gallon bucket with the pool water that's left in the pole. You should then net the tadpoles with a pool leaf-skimming net. You need to drag the net behind the tadpoles and then quickly scoop them up on top of it.
Next you are going to need to hold the net over the five gallon bucket that you previously prepared. You just need to dump the tadpoles that you have collected into that bucket, and continue netting the rest of the tadpoles until you can see them no more.
You're nearly done. All you need to do now is drain the pool right to the bottom, getting rid of the foot of water that you left earlier. You now need to refill the pool and keep your water well chlorinated at all times. Tadpoles will not be able to survive in water like this and hence you should ensure that there are plentiful amounts of chlorine at all times in your pool. This keeps your pool clean and safe to swim in throughout the year.
