I've pointed my powerhead right at it, so it's getting good water flow. I will have to take the water to a LFS for testing cause I don't have a kit. I have a product called coral builder that a LFS conviced me to buy. I haven't been using it for long but is it something that will help with this? Is it a good product in general for someone like me who's just keeping some soft corals and zoo's?
