How to deal with Aiptasia (Pest Anemone)

Three months ago i bought a coral frag that came on a small rock. I later noticed that there was an Aiptasia on it and I immediately took it out of the aquarium and drilled through it. However a month later i saw many small Aiptasia all over the place and unfortunately my rock work is solid and I cannot take it out of the tank. I read that there are products like Aiptasia-X or Joe's Juice that you basically drip onto the Aiptasia's oral disc but honestly I do not want to put such chemicals in my reef tank. Any advice will be greatly appreciated. Here is a picture:
