DE Leaking into pool???

[denanbob]

Are you only having this problem shortly after adding new DE? We are suppose to add 4 lbs. of DE at start-up (we have a measuring cup that is specifically for DE), but it always seems to be a little too much because for a week or so afterwards, we get DE settling on the bottom of the pool. I will vac it up and it will return, but less will be there. We keep this up until it's all gone. Hopefully this may be what is happening with you. I probably should put only 3.5 lbs. in next time, but I'm always afraid I may cause more damage if I put too little in. This "cycle" happens everytime we squirt off the filter grids and put new DE in.

If it only shows up after adding more and lessens with each vacuuming, I'd take a look at the multiport, you may have a little water bypassing the spider gasket - most goes into the filter, but some gets back into the pool.
