Definitely helps! Bonus is that I'm already familiar with sand filters. How about the pump question? I know I don't want to overpower the filter with too big of a pump, and in my 15' AG pool my 1 HP pump was more than enough to circulate water through the whole pool. A 33' pool is a much different monster. I know I'll have to run the pump much more often to achieve enough water turnover through the pump, but will a 1 HP pump even move enough water for adequate circulation all the way to the other side of the pool?
