Alright. Anybody know a "good" way to get rid of flat worms?

What kind of flatworms?

Besides a double dose of Flatworm Exit?

FWE works very well on red planaria. Check out melevsreef.com for a good tutorial.

airline tubing, siphon out as many visible as you see every couple of days for a month or so worked for me. I know its kind of a pain in the butt but it worked for me.

I've been noticing flat worms in my tank for a few weeks now. I'll probably go ahead and use the Flatworm Exit chemicals now before there get to be too many of them in there, since I've heard horror stories of people nuking flatworm infestations and the dying flatworms then nuking their tank.

For now though I've just been plucking them out using my Aiptasia X syringe. It's actually kind of fun. I think most people use a turkey baster.

I couldn't figure out where I got the flatworms from and in the course of a few days I visited both my LFS and saw that their frag tanks were completely invested with them. Guess that answered that question. Next time I buy from them I'll be scouring my new frags for flatworms and getting rid of them before putting them in the tank.

definitely siphon as many as possible, then flatworm exit the rest, and six lines work pretty good

my sixline wont touch a flat worm. I siphone out about 100+ worms a day. Been doing so for about 3 weeks. Havent noticed too much of a difference. Id rather pull them out forever then put any chemical in my tank.

Yellow coris. Mine went crazy on every flat worm in the first five seconds after I released it.

I've got thousands. I've been siphoning them out for a week and it seems to be getting worse. I've read that when they die they release toxins. I don't want to kill them only to have them kill everything in my tank. I'm not quite sure what to do.

It depends on what region of the world the Sixline comes from. I can't remember exactly but Sixlines come from 2 different main collecting ares. One area the Sixlines tear the flat worms up and the other area the Sixlines won't touch them. I wish I would have bookmarked the posting that explained the different collecting areas

My last tank had a major flatworm infestation. Take care of them early on. Once they get a good foot hold in the tank they are much harder to get rid of.

I would be very careful about using Flatworm Exit in a nano tank after I read this guy's story the other day... and that's a 200g.

if you siphon out most of them, then continue to do so after dosing FWE and running A LOT of carbon, you should be fine. I've had to do this on several tanks bc i was lazy about dipping.

Definitely get rid of them ASAP, I only saw one yesterday and dosed my tank with FWE til he melted haha

Flatworm exit is by far the best method. It's super safe and works great. I've used it in a 3g before with no negative impact. The people who crash their tanks with it are obviously not following the directions closely enough.

If I do nothing will they go away on there own after time or will it just get worse? I probably have a thousand in there. When you all say siphon most out, how many would be ok to leave in before I dosed. Not that I'm lazy about getting them out, but I have alot of nooks and crannies I can't get to with a siphon.

I have a reef tank set up and we had a nasty flatworm problem.
Unfortunately you need to get supplies... pantyhose, airline tubing, rubberbands, flatworm exit, carbo and carbon sack, extra net.
On the airline tubing you put a cutoff end of the panyhose so you have a sock like sack, rubberband it on. Siphon out as many flastworms as possible, take your bucket and if you have to you can reuse the water and then siphon more out again. the flatworms will be in the sack so no need to worry about them in the water, you haven't dosed so they haven't dumped any toxins. Dose the flatworm exit. wait the allotted 15-45 minutes. You'll see them scurrying away, they will eventually lift off and float. siphon those out or use an extra net to scoop up. After 1 hour sinch you started put your carbon in your sump/overflow/back chamber. Siphon every day but with a new pantyhose bag on the hose. Only use the flatworm exit one every 7 days. Serious with this, exactly every 7 days for 3 weeks.
My girlfriend had to it before then I got it and she was right on. After the 3 weeks you wont really see any at all any more. Even is its been 1 week and you haven't seen any, still dose it. They can be really super small. I've tried all the other crap and this works. Doesn't really effect your coral as long as you dump the carbon is to absorb the toxins.
If you leave them they'll get worse til they overload your tank.
Let me know how it works out.

Only resort to Fla worm x as a last resort. Point a flash light a point in the tank at night with all the other lights off, the flatworms will be attracted to the light and after an hour or so siphon them out. You solve flat worm problems without medications, cut way down on feedings, use good carbon, and do a rinse on the most seriouly infected corals like mushrooms. If you do use Flatworm x you better have a big water change ready, and move any star fish, hermit crabs and snail to another tank when treating.

I have had numerous problems with flatworms in the past, and as the experiences stacked up my reef wisdom grew... Your reef is like a little balanced ecosystem right? So, if you have an excess of flatworms in your tank they are just part of the food chain cleaning up your excess detritus and whatnot in your water. Do frequent, respectable sized water changes and cut down on feeding. Flatworms are not the problem, they are actually natures solution to your problem. They will wax and wane in EVERYBODY's tank throughout its life cycle depending on your nutrient levels. Just remember if you go the flatworm exit route you aren't really fixing the problem, just postponing the inevitable.

I'm going to try it without the chemicals first. I don't like the idea of poison in my tank. I'll cut down to feeding every other day and start siphoning. Thanks for all the help. I'll let you all know how it worked out.
