Rich Ross from reefbeef has been trying out a few different powered lasers recently and discussing it on the podcast. His seal of approval is enough to sell me on it. He‘s used them aiptasia, mojanos, palythoa(?) and vermetid snails. I’m picking one up in a couple of weeks for vermetids and fun.
This is what they are good for. When you see one or two pests and you can take them out with ease.
If your tank already has an infestation its like using a sling shot against an army.
