It's everything thing you need.Interested but never used a doser before.
Is this everything or do I need extra items?
It a single head doser so if you wanted to dose alkalinity and calcium you would need 2 of them. I have 2 if your interested in them both.I only dose calcium and alk weekly.
Looking automate maybe.
You can PayPal or pay when you pick up. PM me when you want to pick up. I'll put them on my porch wife doesn't want anyone to come in cause of the virus.I will give it a shot.
Let me know about payment.
