Columnaris Wiping Out Tank...Help!

[JuiceBox52]

I just ordered the Kanaplex and Furan-2. I am going to try that and see how it goes because I still have fish dying.

I am also starting a new tank ( 29 gallon) hopefully within the next week or so. Can I skip a cycle with using some of the water and filter cartridge from my already cycled 30 gallon?

The water wont do anything, as the bacteria live on the surfaces. But yes, using the filter media will give you an "instant" cycle

If the other tank has the disease in, then don't use that water.

If you have a clean tank without the disease in, then use half the filter media from that and use clean dechlorinated tap water.

There is no benefit to old water. The filter media of an existing tank transferred over will transfer nitrifying bacteria. Use fresh dechlorinated water in the new tank. I'm sure you realize it, but just to be certain, don't put anything (including fish nets that have been used in the "disease" tank) from the tank with this "disease" in the new tank.

I still prefer live plants, especially floating; no cycling needed.

Thank you all.
I just got a 20 gallon. It was previously owned and used and it is kind of dirty. What is the best and quickest way to clean it?

Perfume free soap and water, or mild bleach but bleach can damage silicon so only leave bleach in the tank for 5-10 minutes before rinsing out.

I started the tank last night and I just tested the water but I'm not sure if it is cycled.
Water Parameters:
ph-7.6
nitrite-0 ppm
nitrate-5 ppm
ammonia-0.25 ppm

I am still treating the ten gallon tank and I have one small adult guppy in there who (I just found out) is pregnant. She was in my 30 gallon with males I and then I moved her to the 10 gal to treat her for columnaris. She doesn't have any more symptoms and looks healthy; should I move her to a different tank or will she spread the disease? I have lost so many guppies that I would like to save this brood if I can.

Keep her quarantined

 

[Silencedogood]

Keep her quarantined

Even if she looks fine? She's obviously healthy enough to have a brood.

Dunno. I just wouldn't risk it with how many fish you've already lost

 

[Silencedogood]

Is my tank cycled yet?

Your ammonia is a little high

 

[Silencedogood]

Your ammonia is a little high

I used the filter media from my 30 gallon and the ammonia is always 0.25 ppm in that tank. Could that be why?

On the fish euthanasia, the most humane method according to an article in PFK a couple of years back is the one I have used for years now. It does sometimes become necessary. I net the fish out onto a couple of sheets of paper towelling, quickly fold the shetts over and around the fish so it is completely covered by a thick layer, then lay it on a hard surface and give it a good whack. You cannot see anything and it kills the fish instantly. To the fish, it is no more stressful that netting it normally. Very humane and effective. The only other method that is as quick is to cut the head off the fish, but with small slippery fish--I can't see myself doing that.

I absolutely agree with Byron on this way of euthanising the fish and I did mention this way earlier in the thread. If you can’t do it maybe get someone else too. In this situation, I think it’s the less cruel way!

I know. Right now they are undergoing treatment and I'm waiting for the Kanaplex to arrive. I think they have the bacterial infection internally. I hope the Kanamycin is effective because I don't think I have any other options.

I doubt it, if I am understanding the question. Ammonia consistent at this low a level seems common, and is often relatd to the use of chloramine in the source water. There may of course be other factors too. If you have live plants and especially fast growers (floating plants are the best for this), it is highly unlikely that ammonia will ever be a problem for fish. Floating plants are often termed "ammonia sinks" for a very good reason.
