More DE?

[PoolDoc]

I couldn't help myself so I chimed in asking if the person tested their water and what the readings were.

It's worthwhile to try to zip it -- I've been doing this for over 15 years now, and I can assure you that info from here and PoolSolutions is NOT welcome in pool stores. Since you do want to be able to go back, you might write your item list on a piece of paper, and use Gorilla tape on your lips, before you go in the store.

You have likely read it, but if you have a visible algae, after you kill it there will be dead algae left over that is very fine and is hard for a filter to catch. I will let it settle and vacum directly to waste/drain.

Thanks for the suggestion of vacuuming to waste. I do plan on it but I was trying to avoid it due to the water loss. I will need to be quick about it.

I opened the multiport valve yesterday and the spider gasket looks to be fully operational. It wasn't bent or out of the track. It looked rather new.

I guess the next step is to open the filter and take a look at the grids. I don't want to put more DE in the skimmer only to have to blow out the returns. Thoughts?

[Shifty]

I opened the filter and the grids looked fine with no noticeable tears or rips. Vacuumed debris is still coming out the returns. I guess the next step is to call for service. Any idea how much a service call on a filter will be?

That's going to vary by area. Down here it's an hourly rate of $75/hour, plus the trip charge of $90 (but I live out in the country). Up there it's likely to be more.

You'll just have to call around to the folks that service your area and see what the going rate is....

I think I may take a shot at hosing off the grids after work. I found some pictures online that resembled my grids. My grids were kind of dark with the caked on DE and possibly dead algae. The pictures in the link below resemble the color of my grids.

If after I hose down the grids and vacuumed debris still comes out the returns, what could be the problem? I was thinking maybe there were a few holes in the grids but nothing was obvious when I looked yesterday.

When putting the top back on the fiilter, is there some kind of lubricant or sealant I should be using before putting the O ring back on? I noticed a small drip coming from the T pin on the O ring after I turned my filter and pump on last night.

This is very frustrating. My water is crystal clear but I am vacumming daily. Any suggestions would be greatly appreciated.

I'd replace the multiport. . . .
