How much should i use when doing a 25%change on a 240L tank

25% of Directions Use the API dosing cap on the bottle. To remove chlorine and detoxify heavy metals: Add 1 ml for each 76 liters of aquarium water. To detoxify chloramines: Add 5 ml for each 114 liters of aquarium water.

Please do not send me this product each month. i only needed the one which is a year's supply

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!

Superb products.

Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.
