Are you sure that was what caused it though? Could it had been something else? I would not think killing some vermetid snails could cause that. It would take a massive amount.How do you thin them out? I took tweezers a while back and crushed a bunch, but the die off after caused a nitrate spike and algae outbreak.
For po4 yo could dose KH2PO4 That cost you about £3-4 on e-bay. Doing that you allow your corals be happy and all competitive organism able to compete with your dinos. Check the Dino treads for exact dosage. Without a microscope you can’t be sure what are you dealing with so I suggest get one cheap one with 40-100x magnificationPo4 has been 0 for about a month. I took out the gfo and have been feeding more and dosing neonitro and neophos slowly. Today I put in new carbon. I think you’re right about the low nutrients. I hope it’s not dinos because those are hard to treat. I’ll just keep an eye on it, remove what I see and not do anything drastic.
Oh that happened a while ago. I know it’s not the cause of the problem now. My guess is that low nutrients is my problem and that raising them will slowly but surely solve the problem.Are you sure that was what caused it though? Could it had been something else?

I had a small salinity drop because my AWC bucket ran dry and the ato dropped rodi water instead. But the problem was before that. I haven’t moved them, no major temp swings, no new livestock. When I dipped the biggest colony, the only thing that came off was a few of those tiny starfish, the ones with red and white striped legs. I’m pretty sure they’re good cuc’s.I would try to get a sample of the brown stuff under a microscope and post a video/picture at 400X if possible. Not all dinos are toxic. Amphidinium in particular is non toxic. Ostreopsis on the other hand is very toxic. Wiped out every SPS I had in my tank.
Any other changes other than the nutrient swings? Have the zoas been moved? Any change in flow? Temp swings? New introductions (inverts or fish)? Look very close for nudibranchs or zoa spiders. Both are sometimes difficult to see. Did anything come off of them when you dipped them?
