White slimy stuff foating on top of my pool water.

1. Run your filter 24/7. Clean as needed, but NOT more than that.

2. Make SURE you have no chemicals, feeders, or devices between the skimmer and the filter. If you still have cal hypo, regular small doses with that IN THE SKIMMER will help capture copper that may otherwise stain the pool.

3. Your chems, in order, are:
+ dichlor
+ cal hypo
+ soda ash (pH UP, washing soda)
+ chelated copper algaecide (chlorine releases it to form stains)
+ HEDP (chlorine resistant metal chelant -- eventually breaks down and forms phosphates)
+ mystery enzyme -- probably doesn't hurt anything.

Thanks for the info!

So, run the filter until the slime is gone, then resume the normal schedule? I have no chemicals between the skimmer and filter and I don't use tabs. How small is a "small dose?" Half the recommended dose for a pool my size? And how regular should I be dosing? I always add dichlor and cal hypo directly to skimmer.

My pool is 15x30 above-ground btw. My pump is a 1 HP Hayward ProFlow XL that sounds like its on its deathbed. Just had a new pump seal and impeller installed. Looking back, I probably should have just replaced it.

Thanks

+ 1/2 the normal dose would be good.

+ If you add BOTH dichlor and cal hypo via the skimmer, make SURE to clean up any granules that don't make it. Cal hypo reacts badly with EVERY other form of chlorine, except maybe bleach. (But I haven't tested that)

+ Sounds like you need the "Sight-flipper" -- it turns hindsight into foresight. My understanding is that they are rather rare, unfortunately.

[Scrapple]

I didn't know about the reaction between the two. I am careful to make sure that all the granules make it through the skimmer.

So it is still ok to add dichlor several hours after adding cal hypo?

When is it ok to shut the pump off? I can see stuff floating near the bottom of my pool that gets stirred up when the pump is turned on. I have another pump question, but will ask in the appropriate forum.

[PoolDoc]

+ An hour separation time is fine IF the pump is ON.

+ Don't turn the pump off during clean up.

Best direction to point the flow nozzle in the pool? Mine is pointed toward the surface and toward the wall to get counterclockwise flow to the skimmer.

Depends on what you need. If you are trying to skim floating things off the water surface, then upwards as you described. But, if you are adding chemicals, I think it is better to aim it more downward.

[PoolDoc]

There's no standard answer to that question. From what little I've played with it, slow circulation is best. If you get a whirlpool going, stuff moves to fast for the skimmer to catch it.
