Seachem Flourish Potassium Supplement, 250 ml

Q: Can I use flourish potassium on hibiscus plants?

Would work on any plants I would think.

Q: 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.

Q: 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).
