OK I have a question for anyone that knows. I have an Sps dominate tank. And have the equipment to make sure water conditions are right to run a thriving sps tank. Now with the equipment that I have to take certain things out of the water, I want to know if zoos and palys can do well or not. It may sound like a dumb question bit I've talked to 3 people that said their zoo colonies are not doing as well cuz there is not enough for the colonies to take anything out of the water. Is this true?
