Good morning all,

Just looking for a little feedback if anyone has used Dimilin-X? We are new to the pond world and a fellow Koi advocate was over to check out our Koi last week and suspected from their behavior they had fish lice. He suggested we use POTASSIUM PERMANGANATE.
I am a little leery after reading about it, to kill all the algae before winter because we are in Ohio and it is quickly approaching. I want to leave the pond as it is and not mess with that to destroy anything we built up in the last two months. But here is the question, my Koi ended up spawning, and to our surprise we have beautiful babies everywhere! Which is another reason I feel the water must be ok, to have so many babies! Due to the fact that they were so late in Spawning (AUGUST, SEPTEMBER) we quickly realized that these little ones were going to need help, so we opted to bring the babies in for this winter. So I ordered the Dimilin-X and was planning on treating the pond, but I felt that since the babies came from the pond, they may need a treatment too, but I can't find any literature anywhere telling me if it is safe for small fish too? Can anyone provide any info??? Also, just an FYI: we used the same pond water and put it in the 300 gallon stock tank in the basement. We felt since they were thriving in that water, it made sense to use that instead of tap water and starting over building up bacteria. Thanks ~ Molly

I have used that to clear up a cloudy aquarium but for lice? I am not too sure so wait till someone smart on here answers before going through with it ... ;)
PS: Your pond is 20k gallons right? That is gonna be a lot of chem unless they make a super concentrate. The stuff I used for my 75 gallon tanks was really thick and red but still took several ounces to do the job. I will at least say that for clarifying water it does work and works fast but does turn the water a red-brown color at first.

I just want to congratulate you on catching fry - that ain't easy! No clue on fish lice though, but I suspect people will tell you that you need to scrape a fish and consult a microscope before you treat for anything.

I would invest in a microscope before I treated for a parasite "just in case".
I would also leave any new fish fry in the pond to tough it out through the winter.
There is no shortage of fish fry in this world.
..just my experience.;)

The bottle is 8 OZ and it will clear up to 25,000 gallons. So it says on the label 1 tsp is for 600 gallons. So if I treat the fry in the 300 gallon tank I would do 1/2 tsp. But I was only going to treat 10,000 gallons in the pond and then it says repeat in 3-5 days, so use the rest of the bottle.

Thank you! Yes, I have spent hours, I mean HOURS with little aquarium nets catching some. Some are about an inch and others are literally as big as my pinky nail!!! So many colors, I am so excited to have the opportunity to do this!

First of all, one should never apply any pond treatment or medication based on an assumption or suspicion. Pathogens should be accurately identified by whatever means are necessary to insure proper treatment/medication.

As to your Koi fry, as MitchM suggested, I would leave them in the pond. They should survive.

I have new fish fry every fall that survive 6 months under ice.
They'll be fine left in the pond.;)

NOW they tell you! ;)

We think of them as tiny little fragile things - they're tough little guys. But I know the excitement of finding babies... it wears off. And then you will agree with Mitch when he says : "There is no shortage of fish fry in this world". Just ask anyone who's trying to get rid of their overabundance! Most ponders learn when you see signs of spawning - stop feeding. Let the fish take care of the population explosion the way nature intended. I figure that way only the smartest, toughest, most creative ones survive.

Wow, I too am impressed you caught the fry, especially with small aquarium nets. My pond is only 1700 gallons and I had a devil of a time catching mine!!!!

Lice can be seen very easily on goldfish or koi without the use of a microscope. The dimilin x is a good choice for treatment. I have used it in the past for anchor worm (bought it on ebay)

You should check each fish over and remove adult lice with tweezers and then spot treat with a little neosporin. The dimilin x does need follow up treatment to make sure to kill any eggs remaining in the pond. Not sure about using it with young fish. Maybe you can contact the manufacturer?

Here is what the lice aka argulus look like http://www.kokosgoldfish.com/Fish Lice.html

Thank you for your reply and all your information! I appreciate you sharing. I haven't caught one of our fish yet but will work on that tomorrow, and check them out! Thank you!!

No problem, Please keep us updated :)
May I ask another question, you seem to have incredible knowledge. Can my water hyacinth be successfully kept with the baby Koi all winter in my basement? I put a few in the 300 gallon tub with them before the frost, and the fry seem to love to be in them and hang out. I just want to make sure there isn't any health risk to the babies by keeping them in there. I was planning to get a grow light for them over the tank? Thank you!!!!

I have never been able to keep hyacinth over the winter indoors. It does great for me outside but not so much inside (although I don't have grow lights) It's definitely worth a try though, the light just may be the trick. If you notice they start to wilt and die just make sure to get them out of the tank so they don't pollute the water.

And don't forget to let us know if it works :)
