its a good sign that if you see these micro coco worm showing on the rock, that most likely means your tank getting more stable, as i kwew, these worm are very sensitive to the water quality. GL!Sorry for taking so long to post but life just has a way of taking you for a ride. I've been fight the tank so much it felt like a bad relationship. It started like a tank would diatoms bloom just after cycle. Then dinos popped up i i feed heavy cyano bloom, then LHA, then Dinos, Cyano bloom x2. It was at this point i told myself something has to change. I've done every i could think of to break this ugly cycle. I decided to replace my entire sand bed. I slowly syphon sand over a few weeks and replaced it with super washed aragonite sand. Im only 4 days in to change the hermits and snails have cleaned the rocks and not a single dino to be seen. The tank has never looked this clean ever. Studying the rock today and noticed all these red dots feather duster had just popped up out of no where. I think the sand bed was my biggest problem from the start. Hopefully regular maintenance and i can keep it clean.
