Find a way to have less hands in a tank. Just the chemistry of your hand being in the tank when you have a lot of corals, they be upset. Some say it’s skin oils… or the physical sense of Just the glove within the water.I put gloves on I have lots of bristle worms and many other things living in there. But I use scissors and a bucket.
But before you get to that faze find a was the ecosystem can do it without you putting ur hands in the tank. I put 5 zebra turbo snails in each tank ever year to supply them with enough food
