I just recently bought a house which has a 15' round above ground pool which was not taken care of. I have never been a pool owner till now so I don't know too much about pools. I have been attempting to use a leaf rake and a leaf eater to clean the pool, however it's hard to tell how much debris is in the pool due to the dark water color. Also my pool has a ton of tadpoles swimming around. I'm trying to clean it in order to SLAM it. Also my pool is currently only half way filled, we had to drain some to get the cover out and leaves that were on the cover. when should I refill it? Any suggestions or advice would be terrific!
