After reading here and at PoolForum, we purchased a vacuum and hose. We have a cartridge filter system in our pool. The salesman at Leslie's said to be careful with vacuuming because there is a possibility of clogging our pipes if there is too much debris on the bottom of the pool. Also, he warned us about having the vacuum submerged when we start or we could damage the filter system by sucking up air.
With these dire warnings, I have been very hesitant to vacuum the pool, but I know that it needs to be done. Our pool is just on the other side of a junior high school track. Every day during the school year (which ends Friday) hundreds of kids run around the track kicking up all sorts of dust which I am sure is the cause of the brown dust in our pool. At least, that is what I'm going with because the possibility of having to kill mustard algae with the CYA at 70 is too much for me to even fathom right now.
Any advice or tips would be appreciated greatly.
