i bought a house last year with the pool right at the end of the season. i closed the pool with a help of my inlaws (who have a pool) without knowing/thinking much. at the end of this winter i pumped some water from the cover (i had a lot) back into the pool. my inlaw advised me on this and apparently he does it all the time.
at that point i didn't think much about it, but with a lot of information i consumed last month or two preparing for the season, i start to question if it was a good idea. the temperature was low (30-40F) when i moved the water so i doubt there was something living in the water. it was dirty and probably moved some slime from left over leaves from the cover. i'm not concerned about the dirt, but maybe i introduced something to the pool water that now is waiting to start to grow since the temps we going up?
was it stupid of me, or is it ok?
i planned to open the pool on memorial weekend (MA - still coldish here), but reading more stuff here, i'm going to check the water temperature this weekend and if it's close to 60f, i might consider hurrying up.
