Help with Dichlor shocking

[ryguy76]

Hi,

I’ve had my tub for about 3 weeks and trying to wrap my head around shocking doses. 

I’m using 62% Dichlor granules and my tub is 300 US GALS.

My FC is currently 2.7 and CC is 1.55.

Is there a rough calculation I can do to figure out the dosage to Shock it with my Dichlor?

Thanks!

Shock based on the size of the tub. 300 Gal is about 2 TBL of dichlor.

Make sure you can test for CYA.
