Discouraged by flatworms

[toadstool_paradise]

So a few weeks ago I noticed some flatworms on my rocks and this week my toadstools were all closed and shedding over and over and I looked closer and I could see dozens of tiny brown flatworms on them. Disgusted I ordered flatworm exit right away. Followed the instructions exactly for my 20 gallon reef. The next two hours I spent siphoning many flatworms from the tank and did a 20% water change with carbon. A few of my toadstools began to open right away and some did not. I peeked at them 3 hrs after the treatment and to my horror, noticed a couple flatworms on top. I’m feeling pretty bad about this still.

Can I do another treatment? If so when should I hit the tank again? I siphoned so many of these darn flatworms I thought for sure they all died. Guess not. Really disappointed
This is a small tank and I already have 3 fish which is my max. If I absolutely need to get a yellow corris wrasse I can and rehome one of my fish I will.
Suggestions are welcome, thanks.

Do you have emerald crabs?

Flatworm exit can ruin a tank it is recommended that you siphon as many Flatworms as possible and use flatworm exit with less flatworms in the tank. Flatworm exit can create a big ammonia spike because of all the dying worms.

Yes I followed the instructions as it says to siphon them before which I did and then during treatment as well. No I have no crabs.

It usually takes several treatments to eradicate them especially if you have a high number of flatworms.

I tend to give the tank a few days rest and then nuke again.

Try 2 emerald crabs. They crush flatworms. Probably one of my favorite reef inhabitants.

Six line wrasse will decimate them.

I was going to suggest one but maxed out on fish.

Ok I will hold off for a few before trying again!

I had an issue with them a while ago, yellow coris, Spotted mandarin, and emerald crabs did nothing. Just kept using flatworm exit and they were gone after 4 treatments. I also dipped infested corals between treatments. Just remember to use new dip for each coral

Yeah I’ve done three treatments and haven’t seen one for a week so I’m staying positive!

I had the same issue, came back after 2 treatments. Added a Pink Streaked Wrasse and I havent seen a single one in my display tank since.

Blue Star Leopard Wrasse for me. Beautiful fish and constant hunters. When the first one hit the water it swam directly up to my large elegance and started carefully plucking them off. Within a week or so there wasn't a FW to be seen. That was a few years ago.

And FWIW - I tried manual removal, but I have other things to do with my life as well. I tried FWE at suggested strength, 2x, and nearly 3x. It took out some, but the ones it didn't came back with a vengeance.
