Used the pool for the first time yesterday. Put in my cholrine (dichlor) last night and left the filter run. Came out today and there was dirt or whatever all over the bottom of the pool. If this is going to happen every time we use it, I'm tearing it down. This vacuum and refill is starting to get really really expensive on the water and electric bill.

Chlorine: 2.6
pH: 7.4

Chlorine is down a touch from yesterday but I'm still confused.

There has to be a better way.

Thanks.
