I will happily read all day with a thumbs up if you are detailing a great experience that you handle with ease.
OK, here goes.
I have been using Baquacil since 1992 in three different in-ground pools. You learn a lot in 28 years.... Several "Aha" moments, in sequence:
First, take out your ladder (permanently if you choose) and any other equipment where the bioslime can hide. Take out your eyeballs and clean them and the return fittings, same issue.
Second, Baqua Floc (Alum, Aluminum Sulfate) is your friend for clearing up haze or slightly cloudy water. Use the lower "filter aid" amount, not at the level for pool opening/vacuuming. This takes the bioburden and gets it out of the pool via backwash before you waste a lot of Peroxide shock. I have only had sand filters so not sure where this would leave DE or cartridges.
Third, Ahhsome. I always saw increased hazy breakouts toward the end of each year and cloudy pool upon start-up, apparently due to line build up. I also changed the sand in my filter yearly to avoid bioslime buildup (when I had an Hayward S-200, PITA). Using Ahhsome to clean the lines, filter, etc. has eliminated both those issues.
Fourth, Solid autocover. Expensive, but after 25 years of solar rollers and mesh winter covers, SO worth it. Have opened clear the past two seasons.
I finally sprung for a ColorQ kit this year. As others have mentioned, may read a bit low on Biguanide but I mainly look at the Shock. A dive in the shock level seems to be the best early warning for a possible water mold/pink slime event.
I only recall one instance of green algae, early in the season on the shaded side of the pool. Have never used the Baq algaecide, switched to CDX program when it came out 20 ish years ago.
