Dinoflagellates

[allendavant]

Ok,so I've got a dinoflagellate problem. What's the best way to get rid of it?

Manual removal. How long has it been. Don't start worrying if they just showed up, they can go away quickly. I had then for 1-2 weeks and they cleared up mostly.

I’ve had them for about 3 weeks.

Pull them out and scrub them really well. Maybe use peroxide on them, one rock at a time though. I had real bad algae issues on three of my rocks so I pulled them and soaked them in tank water and peroxide mix for about 5 minutes. That was three weeks ago and so far so good

What worked for me, take with your own grain of salt.

Three day complete blackout. (Covered tank from ambient light.)

At end of three days, a lot of manual suction, scrubbing, etc, to remove the dead bits.

For the next two weeks, added 1 ml of hydrogen peroxide per 10 gallons of water in the system (EDIT: Once per day)(100 gallons for me is 10 ml). This is of the TOPICAL stuff, the low percentage hydrogen peroxide mix that is used at most stores. Not the heavy grade.


I followed this advice from a local fish store thats been doing it for 30ish years or so. He swore by it, nothing online steered me far away from it, and it worked for me. My problem wasn't NEARLY as bad as yours, and a /little/ came back on the loc-line of my overflow, but it never returned to my rocks or sand.

I removed the locline to clean it independently, and I've yet to see it return again.

.

Did you remove your fish and/or corals while doing the black out or the hydrogen peroxide treatment?

Some strains are relatively easy to get rid of , but others are almost impossible. The first time I had it I fought it for over a year & eventually tore down the tank & started over(with a bigger tank of coarse). That was a long time ago & although I did try the peroxide it was before things like dinoX & vibrant.

What is your no3 & po4? I would guess it is quite low. It isn’t always the case but the majority of the time people people get Dino they have 0 no3 & po4 or its very low. I believe tanks can get almost to sterile Dino loves that environment. They have no other algea to compete with so they can take over. That was my case the last time I got Dino which was in the last year.

I tried just about everything including peroxide, dinoX & vibrant & nothing worked at all. I started dosing the tank daily with phyto & working on getting my nutrients up. I had already stopped doing water changes. Once my no3 hit about 3 ppm all of the brown dusting I would get on my glass started to turn to the normal green algea. Once that started happening the Dino started to go away. I battled it off & on for about a year & am still getting small amounts when my nutrients drop to low. I have to feed a lot to keep no3 in the tank & started doing water changes once a month instead of every week or two. It’s the only way I can keep any no3 in the tank. I can tell when my no3 zeros out because I start to get the brown dusting on the glass & soon after Dino starts to show up on the sand, powerheads & overflow which are the first places it shows up. So I would recommend trying to get some green algea to show up.

Make sure it’s actually dinos. That looks like hair algae with film algae growing on it. Dinos is like bubbly snot/slime. Is that what you have?
