Huge flat worm issue

[whatcaneyedo]

A nudibranch that eats them is often available as well. I tried one once with a heavily infested 50gal. Within 2 months it ate 90% of them but then I think it couldn't find the rest and starved. I should have passed it onto someone else slightly before that happened then treated with Flatworm Exit.

Dose again, this time 2-3x the recommended amount. I'm not kidding. Have a large (50%) water change & fresh carbon ready to go.

I spent a week or two (like Freeze) pre-siphoning out anything I could see. I used airline tubing attached to the feeding probe. Sometimes I'd squirt a little water out of the feeding probe the loosen the nudi's off of the rock. Once you're happy with a couple weeks worth of back breaking siphoning... dose the crap out of the tank. The nudibranchs can become immune to lower doses, and all you'd be doing is ensuring the strongest survive if you dose at the same levels again. Follow the directions closely (aside from dose concentration) and wait until you see them coming off of the rocks. At that point I activated the carbon reactor, started netting them out of the water column with a fine mesh net, and siphoned them out of the nooks & crannies in the rock. I also took a powerhead and aimed it into the rocks to get out the remaining flatworms. Once you're happy with your work do the water change.

Best of luck.

You could get a jester goby
It did a quick job of my red flat worms.
One of the LFS in regina has a bunch of them.

If I want to dip my live rock to kill of some excess red worms how would I go about this?

Cheers!!
