Goodness,

It's been a nightmare. Little insight into my almost reef keeping hobby ender.

The background is I came up with an odd parasite, that'd can be traced to a longnoose butterfly fish I added into my tank. Parasite looked close to Brooke but only took out about half of the fish in my tank. 3 tangs, 2 blennies a hawkish and a well proven copperband. I treated with H2o2 and I do say it saved my reef fish and by "saved" I mean 2 tangs and two clowns made it. Or maybe they were just gonna make it anyways, who freaking knows.

Well... that treatment... started another nightmare. A massive dinoflagellates bloom or what looked to be that. Nasty strings of just garbage covering my sanded, rock and corals. Corals lost colors, some died and no water change or light turn down operation seemed to help... infact it just got worse somehow.

I almost just said screw it, and let the tank slowly stop to exist. I was over it, this was fixing to be my 2nd total loss in 3yrs. My loss came from moving my 150 gal, in a snow storm over a 3hr drive that took longer than i was ready for. Link that with just 1yr reefing experience, but happened to be doing crazy well with that tank and a wing it mentally...basically means disaster. Anyways It's expensive to reset, time consuming and just completely horrible. So I said "there must be a way".

Given the vast Reef material out there available, theories, studies, and just data from trench warfare reef gunts conducted daily. I develop my own plan of attack and theory as to my reefs issues and future development.

1). H2O2 great at killing things smaller than one could imagine... bad for overall Biological purposes in large amounts in closed body of water. (Used for parasite= worked/caused diano outbreak=sucks. ) also blackout didn't seem to matter but I wasn't willing to do over 48hrs (prolly could of worked) however, I was too focused on not loosing more than I have.

2). Beneficial bacteria.

After a few papers by some known Nerds 🤓 in the filed of IDK 🤷, followed by numerous YouTube Nerd reefer videos annnnnd freshwater nerds.... I came to the conclusion that I needed to add this bacteria as maybe.. my H2o2 over dose was causing my problem.

3). Disclaimer... I'm not a Biological engineer, science fiction writer, public aquarium keeper, fish scientific research person etc... but I notice something.

The addition of Chemiclean followed by Beneficial bacteria worked. Tore the crazy outbreak up. And cleared the issue like it never happened.

4). Application.

I added live rock enhance, and Fritz monster 407 as directed. No crazy change, however I could see the nasty strings did start to.back off.

Then I added chemi clean, after 48hr my progress had most dianos held to rock and substrate.

I figured another round of bacteria could clear this, as chemi clean kills bacteria. Added both plus Stability.

48hrs later we were clear and free. Rocks clear and clean, substrate looking amazing (couldn't see it before) and some corals happy.

I only lost 2 branching hammers. So that's my experience. First time with a crazy issue on another issue. Been in the hobby 5yrs have a 150gal 6ft reef mixed and a 220 predator tank.

I'm sure there was a better way. Yet, I found my way lol. Let me know what you think.

Not an expert but in my experience, UV kills off the toxic strain leaving the harmless amphinidium strain in the sand. Those are pretty harmless in my experience but unsightly and very difficult to kill. I tried different chemicals like u and realize it kills corals AND Dino but Dino usually slowly comes back. I realize patience is key against Dino.

I basically realized it was not doing any damage to corals and fish and just “gave up” and let it be. That actually was my saving grace. I just raised nutrient and dose microbacter 7 weekly. And it just went away. I stop losing corals after taking the long route. Just my 2 cents.

I had both large and small cell amphidinium. I tried UV, blackouts, H2O2, bacteria, dosing NO3/PO4, and removing all the sand but still had dinos. Dosed silicates and it worked.
