Can this be used for indoor fish tanks, such as a 1 gallon fish bow to a 50 gallon fish tank?

Can be used for water in all sized containers. I would recommend using either spring or bottled water for something as small as a one gallon (Beta and Goldfish sizes).

Hello can i use this in a 10 gallon tank, and if so how much do i use?

Yes one 10ml capsize dose for that small tank, then test before using again

Hello so i did find out 1ml for every 10 gallons of water. So i m using under an 1/8th of a tsp can anyone confirm my math? Thank you

One full cap is 10 ml (2 tsp) for 50 gallons, half a cap is 5ml (1 tsp) for 25 gallons treatments. 1/2 tsp would be for 12 and 1/2 gallons of treatment Hope that helps.
