to add de or not to add de

[mikemedic]

Hello all,
I am still fighting my green pool.
All my numbers are in line and I keep up the shocking.

I have one question:
I converted form a Hayward De filter to a Hayward Sand filter
The Ec65 to the 244 t sand.
I sure miss the DE's filtering capability but know the sand will do the job.
How many extra days will it take on avg to clean the green.
I have been very agressive with keeping the free cl up according to the chart
Would anybody suggest me addind some DE to the sand filter? I have a brand new sand filter 250 lbs of sand and I read here sand takes a while to break in.
I don't want to clog it up or anything and I just put 32 ounces of polyquat in today. I ran the filter on recirc for a while today to mix up the poly
Any suggestions?

I just converted from the EC65 to the S244T also. You mentioned 250 lbs. of sand - shouldn't you have 300 lbs. in your filter? That's what I put in mine.

[mikemedic]

yes your a correct
I did put 6 /50 lb. bags in
Sorry total of 300 lbs of sand

why did you guys go from a d.e. filter to a sand filter

why did you guys go from a d.e. filter to a sand filter

For me, it was because of ease of maintenance. With the old DE filter, I had no way to backwash. It was old and leaky. I was a nightmare to open with its 15 bolts holding the top on. I could go on, but I will just stop here...

ahh old school, the new d.e. filters do have backwash valves on them now so the only extra maintenance is reapplying the d.e. but that is neither here nor there. You could add some d.e. to coat the sand bed, typically you would add enough to see a 1psi increase in pressure. Just be sure to monitor your filter pressure regularly as the pressure will go up much faster than with the sand filter.
