So I'm thinking of replacing my DE grids as I have some broken pieces on the tops of the grids where they join the manifold (the grid fits snug but 3 of them are missing all or part of the plastic top that goes into the manifold). It's a Pentair FNS plus and the previous owner or pool maintainer...

I was just over at TFtestkits and noticed they say the kit's contents have changed for 2010, just curious if anyone know what has changed? Also is the XL kit worth it or will the reagents go bad before I have a chance to use them all? I'm in SoCal so we have a longer season, but no heater all...

I just replaced my lens gasket for my light a couple of weeks ago and today I noticed its got several inches of water inside of it again. Are you supposed to use something like magic lube or should the new gasket do it alone? Maybe I did not tighten the ring down enough? It's a Pentair...

Does Alkalinity ever drop on its own do to sunlight or bleach or anything else we put in the pool? With a high TA from our water it seems the best way to lower Ph when need be is to add acid and aerate right? Am I missing something?

The 1/2HP Whisperflo (motor is an AO Smith QC1052 from what I have gathered) has spun the rear bearing ( I took off the rear inspection cover and witnessed it spinning in the race) and makes a pretty bad grinding noise, I lubed it and its a little quieter but I know it will fail before too long...

Are these a worthwhile investment over just letting the pump basket catch the debris? The ones with a mesh bag seem like they would trap more stuff than the ones with a hard skimmerlike basket, but I would suspect they might get holes in the mesh and then what do you do?

Do the control pads go out easily? I have an LA Spas, Paradise Model I think that's probably only 2-3 years old. It came with the house we bought out of foreclosure so I have no info on it other than I have powered it up at the breaker box and it powers up with the jets on etc, but the control...

Howdy! Been reading here off and on for the last year and I wish I'd taken the BBB route now that I have a CYA problem and am planning a drain and fill here in the next day or so. I've been adding Cl via an automatic chlorinater and 3" pucks. I've been battling algae and discovered there's too...
