Is this safe for bettas?

Yes! At the moment, my lonely Betta has been living in a heavily planted 40 gallon tank with some trumpet snails. I have been using only seachem products and they have not not affected him nor the snails, negatively. However use caution when dosing - follow directions. If tank isn’t heavily planted I would half the doses...

Can I use flourish potassium on hibiscus plants?

Would work on any plants I would think.

How many ml do i use for a 72 gal and a 75 gal tank?

10 ml per 60 gal. 2 - 3 times a week per the instructions.

Will it work on watermelons

This product is intended for aquarium use. I suppose it would work in a garden scenario, but is expensive by comparison to garden fertilizers (which are great for plants, but generally kill fish if you put them in an aquarium).
