How I killled dinoflagellets

[Cory]

I havent dosed in my tank yet but in a bucket of tank water. Im scared to try it in my tank because im sure itll kill anything algae. However it hasnt killed hair algae after 24 hours. What I used was glyphosate aka Roundup weed killer. I used 5 mls in 5 gallons. Heres the pics, scared to try it in the tank, but thought id share anyway. I may try if they get to plague numbers.
Heres what they looked like before on my new ats screen:

Heres after a 15 minutes under a grow light and air bubbler:

And here they are dead with no regrouping after 24 hours:

Interesting.

What is the active ingredient?
And how does it work?

The ingriedent is glyphosate. It kills all plants, and probably would bleach your coral too fwiw. So if you do try it make sure its a fish only. It works by the shikmate pathway or something which inhibits something from

being formed iirc.

Round-up also has a lot of other stuff that they consider (inert ingredients and not listed on the label) that is extremely toxic to humans/animals. I would not expose this to any type of animal that I cared for IMO.

Yes well said. Im still not willing to try it lol. Originally i wondered if ultra low amounts would kill it and not harm the reef so i dosed 1 ml in 5 gallons. After 12 hours i didn't notice anything so i added another 4 ml.

Im going to try the new ulva macroalgae idea supposedly it has a dino poison, scrubber steve posted.
