First taylor readings

Actually, bubbling water at the return jet is aeration and will cause a rise in pH.

hmm ... I understood from a post by Ben that only a PH down closer to 7.0 will rise due to aeration and that at 8.0 it has no affect?

[madwil]

the effect is reduced at higher pH- the lower pH changes the balance equation of the carbonic acid vs CO2 vs... Some will happen higher, just not enough to really matter...
I think the point being made was aeration causes rise, while resp needs to decrease pH.

[SalemCastles]

I think the point is moot as it's "just not enough to matter" which is why I said don't worry about it right now.

So far all is well but I think I may have to look at my filter/pump setup.

There is very low psi as a general rule. I added some de to my sand filter slowly. Only 1/4 cup, and it bogged the output down. Another time I added some stabilizer for the cya and it bogged it Down bad. Both times I had to backwash after a half a day to try to regain some pump filter effectiveness. I don't even know where to bgin on this one and I'm hesitant to call a pool company because who knows how honest they will be.

Ok so I figured the filter issue. The o ring on the pump trap was on wrong which allowed an air leak and lowered the psi. The trap was filled so I cleaned it and it's running great.

Taylor levels
Fc 8.0
Ph 7.2
Cya around 50...ish
I didn't test ta I forgot.

What is ideal fc anyway? With the Taylor it doesn't mention it.

And man the pool clouded up a bit after two days of straight torrential rain. Come on fc and pool filter!

[Watermom]

With a CYA of 50, you want to keep the chlorine between 3-6. But, since you had a lot of rain and the pool clouded up, you may want to go ahead and shock the pool up to about 15ppm for a couple of days. Run the pump 24/7 while you are working to clear it.

Keep an eye on the pH. You're ok at 7.2, but don't want it to go lower.

Thx watermom!

Hey guys woke up and the pool is milky cloudy. I think the filter is defunct
. We have had itfkr two years this is our second summer w it. Before us the house was not in use due to foreclosure. So the filter is at least five years old and I don't know how they took care of it. Also the fact that all the functions are jumbled and I have no real idea which is circulate or filter etc. I'm going to buy a new filter.the pump is new from last summer. I don't recall size. Maybe 1.5hp. Any suggestionon filtersize for a 24ft pool. The sizethere now I think is a 300 pd filter. Omw to the poolstorenow. Thx

You did backwash, didn't you? Can you backwash now or is it all jammed up?

It sounds like all you probably REALLY need is a new multivalve, as long as the "laterals" in your sand filter are OK. It also sounds like you are sized correctly (re, pump to filter, but your pump is really probably too large, so the 300# filter is a good idea to compensate), just possibly plumbed wrong or have damage to the multivalve.

But, before you just throw money at the problem, put the valve to "circulate", not filter, and see if you get strong suction at the skimmer and a strong flow at the return. If you do, your problem is in the filter or multivalve, but NOT in the pump or the lines.

If not, it may STILL be in the multivalve and you'll have to find a way to cut the valve out and see if the pump is actually pumping, like connecting the return line directly to the pump. If that still doesn't work then, it's not your filter or multivalve, but in the pump or the lines. You can even just disconnect the pump from the filter and turn the pump on for a few seconds--it should be like a fire hose! (I have quick-connects everywhere so it's easy for me to do)

You have to figure out how to isolate each possible source of the problem and show it's working, then move on to the next.

if your filter has the correct amount of sand and hasn't been moved, the odds are, yet again, the problem is in the multivalve. Take it out and look for obvious signs of damage-mangled spider gasket, broken chamber walls, etc.

A new multivalve is a lot cheaper and easier to set up than a whole new filter. Plus, just because your pump is new doesn't mean you don't have to prove it's working. You do, or replacing the filter/multivalve may not fix it.

A little detective work....

There is very low psi as a general rule. I added some de to my sand filter slowly. Only 1/4 cup, and it bogged the output down. Another time I added some stabilizer for the cya and it bogged it Down bad.

I would say that when this happened you were in the "filter" position. Sounds like your filter is working. Lay off the DE and run the filter. Your psi should slowly rise if your filtering properly.

Both times I had to backwash after a half a day to try to regain some pump filter effectiveness. I don't even know where to bgin on this one and I'm hesitant to call a pool company because who knows how honest they will be.

I would bet the ranch that when that happened, you were in the "waste" position. It shouldn't have took more than a minute of two to regain a good flow and lower psi if that was the "backwash" position.
