Hi, I am new to axolotls and Caudata.

Short story: The water where I live is very soft, so I have been adding a modified Holtfreter's solution to my dechlorinated water, to about 20% concentration. Everywhere I see salt baths discussed, the recipe is 2-3 tsp Kosher salt, per liter or dechlorinated water. And when not bathing, the axie should be in plain dechlorinated water. How do I adjust this recipe if the axie has already been living in 20% Holtfreter's?

As in, when I make a salt bath, am I adding Kosher salt to literally plain, dechlorinated water (that is too soft for axies' comfort normally)? Or, am I adding Kosher salt to my 20% Holtfreter's treated water? I know too much salt can harm them. But if the water in the baths is too weak, I'm concerned it won't do any good.

My axolotl has been fridging, and so far I have done 3 days of salt baths, 2x a day. Out of fear of harming them with too much salt, I have had them in a Holtfreter's solution diluted to about 10%, and for the salt baths I have used plain dechlorinated water, and added the recommended amount of Kosher salt. I've changed the main tub of water daily, and was planning on continuing today-Tuesday with 1x daily baths. However, I realized I needed help determining if the waters I have been using are too much, too little, or enough. Does anyone have experience with this? Anything helps.

Full story: In August I took in 4 juveniles (Bilbo, Kaiju, Pippy, and Ponyo - Bilbo and Pippy to go to my mother's once they were a bit more grown) from a friend whose pair had babies. She hand raised the baby axies, and then found them homes, but is not a professional breeder. I have a 30gal tank set up with a bubble bar, an AquaClear 70 filter, a USB fan to help keep the water cool, and a digital thermometer. Decor is some simple plastic plants, a faux log, some rocks, and a terracotta pot. They've been eating Axolotl pellets, bloodworms, and brine shrimp (thawed, Omega One brand). The temperature sometimes varies a bit throughout the day, but stays roughly in the mid 60s. I had been battling some cloudy water (no one warned me how much waste these guys can make, lol), which caused the ammonia and nitrites to be higher than ideal. But by doing regular water changes, minding the filter, and using a turkey baster for waste, I had managed to clear it up. PH and nitrates have been consistently good. All four had been enthusiastic eaters (and poopers), very active, and grew from 4" skinny bug-eyed babies to robust and 7-8", with fluffy gills. Around a month ago, one of my greens (Bilbo) started exhibiting some floating behaviors (couldn't stay down, didn't seem in control of their floating). I spoke with my friend (original mama) and did some research, and found that Bilbo probably had a bubble in their tummy and once it passed, they would be fine. I did remove them from the main tank into a smaller tub, so they could touch the ground. The floating started to make Bilbo tilt to one side, and within 48 hrs they passed away. It was very upsetting, but I chalked it up to something internal I would not have been able to fix. Then, last Monday, Pippy started exhibiting a similar, but less dramatic floating behavior at the top of tank, and I was really worried. I again removed the axie from the tank and put them in a tub, because I had read that not being able to touch the bottom of the tank / control their own movement can stress an axie even more. Within 8 hours, Pippy passed. Then, I woke up on Tuesday morning to find that Ponyo had also passed, at the bottom of the tank. Kaiju is all I have left, and ate pellets that morning / was being active. I removed Kaiju from the tank and began fridging out of fear they were next. I didn't fridge the others before because I didn't think it was needed/ was unsure they were large enough to be fridged safely yet. Shortly after being placed in the fridge, Kaiju vomited/pooped (I didn't witness) up quite a bit of partially digested food, plus the largely undigested pellets from that morning. I took it to be a good sign. On day 2 of salt baths described above, there was some white fluffy/floaty stuff, which I am unsure was shed skin, or maybe fungus(?). Bilbo and Pippy showed no change in behavior or appearance until close to the end. Ponyo showed no signs I was able to identify (such as gill fungus, etc).

Sorry for posting such a long essay! If anyone has any idea what may have happened, I would really appreciate the help. I'm not sure what other relevant information I can include here for reference, please let me know though. I want to do as best I can for my remaining baby. Please go easy on me if there's something obvious... This whole thing has had me really torn up. Based on their growth, appetite, and activity, I thought I was doing an alright job. I became really attached to them and getting to know their little personalities.

Thank you,
Miranda

Sorry for your loss...

Are you frequently testing the tanks water quality? This kind of issue brings me thoughts of high ammonia or high temperature, mostly. The foggy water usually is a sign of unballance on your beneficial bacteria cycle.

If you could post pictures of your axolotl, it would help identify any problems. Also add a pic of its tank.
 
What are your actual tank parameters?

ammonia
nitrite
nitrate
GH - tap and tank
KH - tap and tank
pH - tap and tank

Do not just do salt baths

Also holtfreters is generally a 50% concentration - John Solution is a 20% concentration

What is your actual recipe as it may be off or too low a concentration

Sorry it took a little bit to get back to you, busy with the holiday. This is a picture from a few days ago I had handy on my desktop. They look the same now as far as I can see but I can get a new pic too! The poo was of course removed. And, pic of the tank. Anything I can get a closer pic of?

When I was battling the foggy water I was testing once or twice a week, before and after I did decent sized water changes. I admit that when I finally got the foggy water cleared up, I did not do a water change or test the water. I was worried I would throw off the bacterial balance again if did a water change, and forgot to test. Maybe something spiked and became too much to handle.

I'm using the API Freshwater Master Test Kit. This is the tank water after filtering for a week with no water changes. Axie is still in the fridge, fresh water daily.

ammonia: 4.0 ppm. Big yikes.
nitrite: 0 ppm
nitrate: between 0 and 5 ppm (yellowy orange color)
pH tank: 6.4
pH tap: 7.2 - 7.6 blue color
I don't have anything to measure GH and KH - do you have anything to recommend?

The recipe called it a Modified Holtfreter's, so maybe it is also called John Solution(?). Recipe is 4 tsp Calcium chloride, 1.5 c non-iodized table salt, 1.5 tsp Potassium Chloride, and 3 Tbsp Epsom salt, mixed in a 2.5 gal jug of dechlorinated tap water. 1/2 cup of this solution to 5 gal dechlorinated water was supposed to be giving me a 20% solution for the tank.

I feel like it may just have been the ammonia unfortunately. It had been .5 - 2.0 ppm during the cloudy water period, which is why I was doing 50-75% water changes twice a week. I also bought an ammonia insert for the filter and that helped significantly, though I don't remember the exact parameters of all water values. I purchased a new one for the filter today. Any tips on keeping it low other than what I'd already been doing? I don't want to sound like a total idiot but they kept eating, growing, swimming, etc, so I figured while it wasn't perfect, I was working on it. :/
 
You have an uncycled tank
Get any axolotls tubbed and do 100% daily water changes until your tank is cycled which could be a month or 2

HERE is my handout on cycling there are many out there.

API sells a great GH/KH test kit
