Initial DE dosage on green pool startup

[Water_man]

I can't knowledgeably say that your Anthony filter won't take 8 lbs DE, but for Hayward filters, it's 1 lb/ 8 sq ft of filtration area. I think that 4.75 lbs would be enough for your filter (see above), but as I said - I'm not familiar with your brand of filter. I hope that you can find some useful info in what I wrote

Oops. I actually read that the recommended dose is one 1lb coffee can per 5 Sq Ft, not 1 lb of DE per 5 Sq Ft. This means exactly 5.75 lbs of DE for my 38 SF filter as you posted. Perfect.
This is what I'm gonna do.
Since we're at it: What do you think about BioGuard’s Sparkle Up filtration aid added to the DE? I suspect it's a waste of money.

This is going on my refrigerator!

It worked. I cleaned my green pool with heavy shocking, many backwashes and refills with DE up to par, not missing a single pound.
