Here is my report. After a total of 2 weeks, the SLAM was complete. I think removing the cover helped a little, but it was strange because my cc seemed to vary from just over .5 to 2.0 during the last few days of the SLAM. Is it possible that there was some black algae lurking and...

Thank you. Will do. I'll try to just use the pucks for vacation. I'll let you know the outcome on the cc.

Thanks for your quick reply. I'm trying your advice. Without the cover the cc was down to 1.5 this morning. The cover has been off all day, and the cc is still 1.5 and I can smell it a little. I'm not adding any bleach, but the feeder is on. FC has gone down to upper teens, and seems to be...

I have slammed before, with great results, but I'm having trouble this time. The water cleared to look great after 4 days, the pool almost passed OCLT, cc was 1.0. Pool still looks great, but OCLT is still too high, and cc is now 2.0! I neglected to check the pH before I started:rolleyes...

Success! FC has been between 17.5 and 27 for a week and my bleach use has gone from 4.7 jugs six days ago to no jugs needed today. It's really true; the sanitizing level for my pool is 17-25 ppm because of the high CYA. It does not seem harsh, nor does the bleach smell particularly strong. I...

Thanks for the advice that I have not been able to follow yet, due to current time constraints, and a hesitancy to want to add 8 gal of bleach every day. I purchased 18 gallons today, and used 3 in hopes of raising the FC to 8. My pool still looks clear and beautiful. Perhaps this is because...

We did a backwash and added some water, so I did several tests today. After adding the 8 1/4 gallons of chlorine, the chlorine was 25. It probably wasn't all mixed; this morning it was 6ppm. This afternoon it is 4ppm. CYA is 208, and pH is 7.8. I think the improvement in cya may be partly due...

The cya is 240. Looks like I need to add 1055 oz. of 10% cholrine. I'll do that this evening.

You're right, the cya is 200

Test Kit Results: FC=.5 CC=.5 CH=800 TA=270 CYA=100 I was using tablets and powder shock from a pool store until recently. I see I have some problems here. In our area dumping pool water is not feasible since we have water use restrictions. Any good advice would be appreciated. I have been...

Thanks, so much. I have no drop tests now, but should receive the TFTest 100 middle of next week.

Right now the water is almost clear, but I'm concerned about leaving it at 0 FC for a few more days while I wait for the test kit that I'm about to order. Do I need to add anything while waiting besides tablets? My inground, concrete, 35 year old pool holds 32,000 gallons and has a sand...
