First test readings of season

[michael3]

I added my 2nd dose of DE about 3:00 at 9:00 my pressure has risen about 4-5 over the 1 pound increase from adding the DE. Is that pretty normal psi rise? I didn't expect a 8-10 real fast but realistic how long does it usually take

how long does it usually take

There's no answer to that, except to say that it depends on what's in the water, and your filter. I once spent the night babysitting a vacuum DE filter that was below water level on a 240,000 gallon Girl Scout pool: it was stopping up ever 15 minutes due to an algae infestation, and would flood if not cleaned and handled promptly.

@Ben:: Would you suggest to Michael (and myself) to stir or brush the floor and walls during this process ??

[PoolDoc]

Slimey or green walls & floors need to be brushed. Otherwise, I'd prefer to wait and vacuum what settles. BUT, that's preference, and not necessarily 'THE BEST WAY'.

OK... Conversely, Should we be vacuuming to waste during this process ? Reason i ask:: is that this is the first time of the season I can actually SEE what's in the pool..(and it aint pretty). I'll take that question one step further and ask if I DO vacuum to WASTE, would i be losing the DE as well in the WASTE mode...?

[Watermom]

If there is lots of debris in the bottom, vac to waste. Using the waste setting bypasses the filter so you would not lose the DE.

Im actually surprise H2O-Mom, that i got up as much as I did vacuuming blind..... Thanks as always..>!
