Cyanuric Acid

We have always replaced the sand for no apparent reason. We just thought you were supposed to replace it for efficiency.
I think someone (pool store) told us that a bigger pump would cut down on the time for running filter! We never questioned it. Will definately talk to husband about replacing for next summer.
We are in NW indiana and have only about 1 more month of swimming then grandkids go back to school and no one will use it for the next month (at least that is the way past summers have went). We usually cover pool by mid Sept. Maybe this year we will wait until leaves start falling in Oct.

It's easy to forget that the pump turns the water over--it's the filter that actually cleans the stuff out of the water. Granted, a bigger pump may turn it over faster, but if the filter can't handle the load, then it's defeating the purpose (and actually more expensive) to have the bigger pump.

This would explain why my water is clear but a different color blue. I am using a skimmer sock until we can replace filter or pump. Amazing how much crud the sock filters out. Problem is I have to clean it every couple of hours or so. I am noticing some gritty dirt (sand) in the sock. I'm thinking the filtration has been the problem all along.
Would the filter be throwing off sand?

If the pump is too powerful, it can force stuff right through the filter and into the pool. Over time, it will also damage the filter.

Bingo! This has been the problem all along. Why dead algae would not filter out, dull water, and pressure never going up on filter. Pressure has been at 18 all summer, never up-never down. No dirty water when backwashing, either!
Thank you so much for all your help! I wonder how many other people leave out vital information when they present a problem to you? When I read the word "channeling" and read about recirculating water w/o proper filtering (someone's thread on pool forum) something went off in my head. This forum is the best resource for pool owners ever!!
My problem started off with algae and dull water color afterwards. Now I get it!
I feel like I am rambling so, ttyl!!
