When you ordered you should have clicked one time purchase rather than subscribe and save.. it’s not on all listings so double check before clicking buy

How much would you use for a 22l tank?

We put 2ml in our 25 litre tank which is more than you need .you can get small syringes from chemist to measure tiny amounts.this is rally good tap conditioner .

Do you dose for the amount of water you are changing or for the entire volume of the tank?

It should say on the bottle the dosage is for tap water. Having said that if you dose the water for the entire volume of the tank it wouldn't do any harm. You just run out of conditioner a lot faster!
