added 121 l of bleach. I will test again in the morning. Is there no need to float tablets with this method? if not I have a neighbor that has a blow up pool that will use the tabs.

Re: using the bbb chart
I checked the cl level this morning it is hard to tell with this tester. still looks like its near 20ppm. What i did see again was what appears to be sand in patches on the bottom of the pool again. I was told before this is decaying algae?

Re: using the bbb chart
I am adding a 121 oz of bleach each evening to keep the cl level at 20ppm till my tester comes in, can anyone tell me why areas of dirt keep showing up on the floor. Is this algae that is decaying in the water?

Re: using the bbb chart
Sorry, you didn't get a helpful reply.
I assume the problem is still going on? If so, FEEL the dirt particles.
=> If it's sand from your filter you'll be able to feel the particles. If it's sand, try using the "rinse" position on your filter valve (assuming it has that position; most do) for 15 seconds after you backwash. Then turn the handle to "FILTER". Sometimes, if the pump is pushing sand OUT of the filter during backwash, some of the sand will get into the pipes, and then into your pool once the FILTER position is again used. The RINSE position can avoid this.
HOWEVER, you'll need to watch out for sand loss: if it continues to occur, you'll end up with a filter that can't filter!
=> If it's NOT gritty (like sand) but will sweep away, there's a good chance it's mustard algae. Let us know, and we'll help you with that.
By the way, I've upgraded your forum privilege level.

Re: using the bbb chart
I have continued to run the cl at 15 +ppm, waiting for the rest of my test kit to arrive. I had the same sand looking issue last year. I always rinse following a backwash and I have not backwashed following a vac and the sand still is showing up. Its not in great amounts, but in the creases and bumps of the liner. Any Ideas?

Re: using the bbb chart
Is it sand?
Get some and see. If it REALLY is sand, it's almost certainly from your filter.
Re: using the bbb chart
I just checked it, it is not gritty and if you move your foot or hand over it , it goes away. Its a very light brown and only in small depressed areas or where the liner is wrinkled.

Re: using the bbb chart
Could it just be dirt? In most every pool, dirt likes to settle along those very areas that you mentioned --- in depressed areas or in wrinkles or seams in the liner.
