crystalpro Turtle Mineral Water Conditioner, 4.22 oz, for freshwater tanks

The 4.22 oz bottle closes with a drop cap that holds 7 ml when full, and about 15 drops equal 1 ml.

What the mineral formula contains

The formula is built around a mineral blend rather than a single additive.

The drop cap is made to measure small volumes without a separate syringe. Each capful is 7 ml and about 15 drops equal 1 ml, so the same cap covers both small doses and the larger volumes a tank or water change may need.

• It is a concentrated mineral mixture for turtles and all freshwater creatures (F1).
• The bottle is 4.22 oz and closes with a drop cap (S2, F11).
• One capful measures 7 ml, and approximately 15 drops make 1 ml (F13, F12).

Questions about the turtle water conditioner

How much do I add the first time?

For the first dose, use 1 ml per 10 litres (2.5 gallons) of water. The drop cap measures that 1 ml as roughly 15 drops.

How much is used at a water change?

At a water change, use 1 ml per 5 litres of water, twice the first-time rate for the same volume.

How many drops make 1 ml?

Approximately 15 drops equal 1 ml, and one capful is 7 ml. Both measures are marked by the drop cap on the 4.22 oz bottle.

Dosing with the drop cap

For the first dose, use 1 ml per 10 litres (2.5 gallons) of water; later water changes take 1 ml per 5 litres. The drop cap lets you count drops instead of pouring: about 15 drops give 1 ml, and a full capful is 7 ml.
