Hi, Can I use the Algaefix to 15 gallon water tank?

Hi June,You can definitely use PondCare Algaefix on a 15 gallon tank. API also sells the exact same Algaefix for aquariums. Pretty much the same product but different labels.

Is this safe for pond trapdoor snails?

Yes, this is ok to use pond snails. Please be aware API Algaefix removes snail's food source. You may have to supplement feed.

How much pond algeafix can you put in 15 gallon fish tank?

API Algaefix is a great product to control your algae concerns and comes in different packaging. The packaging for ponds is to be used in ponds and the packaging for aquariums is to be used in aquariums. Algaefix is a registered product with the EPA and strict guidelines such as distinct packaging is required. If you are dosing 15 gallons then the dose would be 1.5 ml per 15 gallons. It is important to follow all label instructions when using any EPA registered product.

Will this affect the pH of the water? And it is safe for plants? Even in a deep water culture garden?

it will not affect the PH and safe for all plants even in deep water also follow the instructions on the container
