Thank You Ben...

ATA- adjusted total alkalinity

I have always been told to turn pump off before adding acid but what you say is to leave on for at least an hour. Do I have to turn it off after that?

I looked at both the test kits you mention and not sure of the differences. Which one do you suggest I get, please?

They do not have the DE so I put Pro Team dry clarifier. Is that ok or should I not add anymore when I backwash?

I just changed the sand in my tank last week. I saw on a post talk about motor/pump size for filter. I just downsized from a 2 hp motor to a 1 1/2 hp motor and pump with a sand dollar 40 tank which holds 150 lbs of sand. Is this the proper equipment to run together?

I greatly appreciate this forum and have founds some great information.

Thank you,
MarineCorpsMom
