Hello all, in the past few days I have lost both of my 2 conchs and all of my nassarius snails have come to the surface and are just standing in one place. I know one is alive because it flinched when my finger got close to it. They have been like this for a few days now. I am currently fighting a nutrient imbalance and have a mixture of hair algae and a few other types I haven’t identified. The tank is a year old and I have had some coral and a bta nem, which I got when things were going well a month or two ago, and neither are acting healthily. My zoas probably don’t like the change in light as it is more powerful however my Duncan used to be very full and healthy looking but now looks very deflated and wrinkly. What do you guys think is happening? I also recently did a 5 gallon wc to clean the sand as well. Thanks.
