The Bill is now due. The beat goes on.

Haven't heard of Diquat. How the heck does a herbicide do the job? Sounds wild. So far the java hasn't been bothered at all from the meds.

Doing the fresh water fill up right now, should be done in 40-45 minutes. Another filter clean. Using cold water out the tap with BARELY any warm water. Have to say the aquaclear 100s are really doing their job pulling out stuff. Filters not nearly as dirty this time around with the floss.

For once no news is good news.

Interesting videos. Only thing I disagree with is Melafix which is snake oil as far as I'm concerned. Interesting some treatments work with some fish, not others.



Father Fish speaks up!


The salt treatment option. It did knock it back for awhile once, but maybe I didn;t use enough. Supposedly the bacteria doesn't survive in salt concentrations.

Diquat works pretty well for columnaris. it is an herbicide so make sure you are comfortable with moving or losing your plants.

I couldn't find any info linking Diquat to treat fish disease? I just found info on waterways and koi ponds that it's used to destroy excessive weeds and algae types. Also says you need protective gloves and goggles. If you have a link I'd like to see.
 
Latest update.

Everyone still hanging in there. Except for little Fric and Frac, no one is interested in eating and all the larger fish are hugging the bottom, tucked up under plants. This is no surprise since between the meds, cool water and complete tank rearrangement they're likely disoriented. The upper half of the tank is now open except for the log reaching to the surface. Hrps will not explore open areas at all given a choice so this is pretty consistent with their behavior. I added salt this evening and a couple of heads poked out from hidey holes.

So I have the Kanaplex and the Furan-2 should arrive tomorrow. My only immediate concern is Outlaw Baby. I can't find my tiny hrp anywhere and am hoping he/she is just snuggled up and hiding. For those of you who aren't aware, Outlaw Baby is the tiniest of runts, no bigger than a young guppy at about 1 inch.

The most effective meds I have used to treat columnaris is either the combo of nitro/kanamycin or back in the day, acriflavine or potassium permanganate.

Never heard of salt so I looked up some studies and it seems at at 2%-4% salinity as a short term bath, there was less columnaris bacteria but still 100% mortality according to https://pubmed.ncbi.nlm.nih.gov/16060264/

However, as a long term bath, 0.6%-0.8% salt added to a tank reduced mortality up to 75%. Interestingly, at 1% salinity, the mortality actually sped up or increased. I guess the takeaway is that a bit of salt does a lot of good but we shouldn’t use too much! This is according to https://pubmed.ncbi.nlm.nih.gov/35796511/

However, neither study showed salt eradicates columnaris in vivo….only in vitro at higher concentrations. So I still think it’s a better option to used nitrofurazone and kanamycin combo

Amazing...when I used salt one time it was at 5% in the 125. I just left it in there a week at a time. The fish who died were already removed but no other exposed fish died or came up with symptoms. It wasn't until I went back to regular water changes that the disease eventually came back. Then it became chronic off and on, 1-2 fish at a time. But I was off the salt at that point. This outbreak has been the worst as far as losses (5) in a very short period. I never made the connection because I only tried that once.

Seems like the sweet spot is 6-8%. PH here in D.C is 7.6-7.8. Might have to go back to low level salt as a controller. I thought the comment about replacing lost electrolytes with those 'shells' interesting.

Tonight I used the light amount before the meds arrive tomorrow. Came to just under 1lb of salt

1 tablespoon 5 gallons

25 tablespoons = 13 oz for 125 (salt) ~1lb salt

The heaviest dose according to the last video calculates to

2.54 teaspoons x 125 gal = 317.5 tsp = 53 ounces salt = 3.31 lbs of salt

which is exactly the dose I used the one time. Anyone with experience in the lab or fisheries feel free to chime in.
 
The dosage in the study was actually 6-8‰, which is per mille.

So, 6‰-8‰ actually converts to 0.6%-0.8%, not 6%-8%, which is a lot less than what you calculated above

Ok, went back to my pencils, scratch pad and ruler. So let's see if I got it right this time.

At 6%
473176 milli in 125 gallons
473176 /125 = 3785 milli per gallon
3785 x .06 = 227.1 milli
227.1 milli = 8 oz salt

At 8%
473176 milli in 125 gallons
473176 /125 = 3785 milli per gallon
3785 x .08 = 302.8 milli
302.8 milli = ~11 oz salt
