Hello,
I am wanting to up my water hardness and was wondering if anyone has used something like CaribSea Aragonite Aquarium Sand to achieve this.
Also when I tested my water this morning my nitrates are super high. What might be causing this?
Ph 7.5
Ammonia 0
Nitrite 0
Nitrate 160ppm

Can’t answer the hardiness question but nitrates are probably high due to the amount of waste axolotls produce. Nitrates are the end product of the nitrogen cycle and are the least harmful; however, they are still harmful in high concentrations.

How often are you doing water changes and what size is your aquarium?

I change about 10-15 gallons every 3 weeks. I have one axolotl in a 40 gallon tank with a canister filter.

That’s probably why. I would probably do that weekly and for now I would do a 50% water change and then daily 25% water changes until you get the nitrates down to around 20ppm. In fish you don’t really want them going over about 40-50ppm. I’m not sure how sensitive axolotls are with nitrates in comparison (maybe someone else can chime in), but that’s what I would aim for.

*aggressive cursing ensues* my whole response just deleted. *siiiiigh*

Okay, you are looking for your nitrates to be between 20 and 60 ppm. To keep it here, once you have it under control, you will need to do 20% water changes weekly, even with a filter ? Another thing that will help immensly is cold water, low light plants. I'd recommended marimo Moss balls that are bigger than your 'lotl's head and hortwort, though I have also heard duckweed is great. For hornwort make SURE you rinse it before adding! I didn't and mine took a giant dump of needles into my tank ? Live plants feed on nitrates and increase oxygen in the tank!

Now to answer your second question,what you are looking for is Holtfriter's Solution. It adds safe minerals to increase your water hardness while helping keep your axolotl healthy. Apparently anyhow; my water is naturally full of limestone so it's crazy hard and I've never used this myself. A lovely lady on YouTube provides a recipe to make it as well. Here's a link if you would like it:

I've used aragonite before, and it seemed to work pretty well for increasing hardness and raising pH, but I have not used it with axolotls. I think it works pretty well, but I don't know if it's safe. I've never used any substrate for my axolotl tanks.

    It’s very dry in Colorado. I make sure to spritz every night so while I’m sleeping. I have a nifty hydrometer that I got from Walmart. It tells me blue, green, red; too little humid, good, too much respectively. It’s been helpful to me.

    Hey y'all, recently my juvenile axolotl's tail has been floating and can swim down but his tail lifts to an angle and I believe that it is stressing him out. He gets in between his plants to balance himself and I am cleaning out the bottom of the tank with my baster. I believe I overfed him and he also may have eaten many air bubbles. He's been like this for nearly 1 1/2 days.

    Should be. Hot glue is good when dry I believe, just don't let it get too hot and you should be good. Most super glues are good as well just watch out for flume warnings
