All last summer and this winter its seems i can never keep dirt out of the pool!!! My wife nags me because she thinks if i would have gone with a pressure side cleaner that it would stay cleaner (her mom and sister have them and they stay spotless with dirt). I opted for a robotic nitro wall scrubber, which i have been happy with. What causes so much dirt to get in? We live in the country and they farm around me do you think its dirt in the air that lands in the pool? I am using zeobright in the filter, could that be the problem? We have two returns in the steps and they always seem to have dirt on them, could the filter not be pulling the dirt out? Any ideas? If anyone needs more information to help cure this problem I can answer.
