Hello all, I am new here but have worked with salt water tanks for a good portion of my life(mostly raising jellyfish professionally). I am however am a little new to growing corals). I had a new 40 gallon reef tank with some frags and a couple of fish. I decided to swap out my rock for the black rock from addictive reef keeping. I didn’t wash it and I didn’t let it cycle( I know both are mistakes but I haven’t had difficulty in the past doing either of those things). Well this turned out to be a big mistake because in 12 hours it killed all of my frags and all of my fish and invertebrates. I checked my nitrates and phosphates both were zero. It’s been a week and my water is crystal clear and dead. Nothing is growing in it not even algae. My nitrates and phosphates are zero but whenever I plug in my skimmer even on it’s lowest height it goes crazy producing a super fine, clean foam almost like there is soap in the water. I’m stymied I have no idea what is going on. Any insight would be appreciated.
