Unclear coating

Ashley5975

Hello everyone! I have a 54-liter aquarium with LED light, current, and a backpack with anti-phosphate and carbon. The aquarium was doing fine for 2 years, overgrown with corals... But then it decided to crash (overdose of levamisole)... In general, I drained it, started to restock, everything was good and stable, and then I left... Upon returning, I saw a painting: the entire aquarium was covered in filamentous algae... But the algae were only part of the problem: the hands, the hermits, and two small sea urchins practically dealt with it... HOWEVER, there was still a persistent brown (rusty) coating on the sand and rocks... It did not affect the corals at all. The siphoning only gives results for a day. Regular water changes do not yield results. Phytoplankton for a week - no results. The urchins clean it, but it comes back. CyanoClean, A-Bce, ZEOStart3, Bio-Mate for almost 2 weeks have not given results... (along with water changes and thorough siphoning). Darkening at night gives results, the amount of "rust" decreases, but after an hour or two of light, everything returns. Darkening for 3 days: the same thing. I am attaching photos. In person, the color is exactly reddish. If I don't siphon, it resembles a bacterial bloom like on LPS (for example, on euphyllias), with a film that ripples... I really don't know what to do anymore... I've been fighting for 4 weeks... I'm thinking of drying the rocks and soaking them in RO water... but there are corals on them - it's a shame... Any ideas? P.S.: The water is RO, everything is normal in the second aquarium. The salt is Tropic Marin.

Thank you! I have already tried all non-chemical methods... Today I added 2ml of Dino Remove from Aqua Connect... It costs more than DinoX, let's see what it will do... For 54 liters of volume, I poured in 2ml of this "wonder" (according to the instructions, 5ml per 100 liters of water and to use it until it helps). I moved the urchins and hermit crabs to the sump of the large aquarium, rinsing them briefly with water from the large aquarium beforehand. After this treatment, I will add fresh live rock from the large aquarium, add zooplankton, and pour in phytoplankton... Because two months of fighting have yielded nothing...

Restart it, don't struggle. Your entire flora is gone, you wrote yourself that there was an overdose of levamisole and then it all started. Why pour different chemicals into such a small volume again? You'll be fighting for another six months while emptying your wallet.

I can always catch up on that later, but while there is such an aquarium, I can experiment to know what to do in case of anything... And maybe my experience will help someone. Reporting: Yesterday, I stopped adding plankton and KZ supplements, and I poured the first dose of 2 ml of "liquid" and turned off the light. This morning, I repeated the procedure and turned on the light after 3 hours. Photos from yesterday "before" and today after an hour of light.

As of today's report: Day 3 Fan coral, tubipora, leaf montipora, common montiporas, tubipora, shrimp, fish, hermit crab (left 1), umbrellas, pavona cactus, Kenyan tree, sponges are not reacting to the addition of Dino Remove from Aqua Connect. Dino has disappeared by 95%, visually. I will continue adding until Saturday, and then I will assess. The filament is still present, but it seems to be starting to recede. More to come...

No losses? I'm interested in any losses, for example, if the stomatella slugs are gone, or anything... and regarding the fish, corals, and other invertebrates. How is the wildlife feeling overall? Also, please let me know if Dino comes back or not. Thank you for the report.

At the moment, there are no losses. The corals seem to have opened up even more... But that's subjective. And the light is currently working only for 4-6 hours. The vurdumani shrimp are running around and eating everything except for aiptasia... The blue-legged hermit crab is active. The fish are indifferent. I removed the snails before the application, just like the urchins...

Day 4: No losses, no visible dino, etc. I don't observe. The remaining thread seems to be withering...

Michele

Day 5: I don't observe Dino/cyano and all that nastiness, the thread is withering... if you direct the current, it falls off by itself... but not everywhere yet... However, one type of caulerpa doesn't react much... And removing it manually is a disaster... No one eats it except for urchins. But I won't return them yet, I'll be dosing the "miracle liquid" for another 5 days, to be precise, the homemade one... Shrimp, fish, small snails, hermit crabs, feather duster worms, corals - everything is doing great.
