Can I keep cardinal shrimp in my water?

Straight from the tap -

TDS - 126
Ph - 7.8-8.0
Kh - 1-2
GH - My new kit is defective :/

Living in Florida, the well water has always been hard. I've tried cardinia with a low amount of success. Neos as always, have been easy, but lately they've been incredibly boring. The original copper pipes in my house were replaced with pvc and I no longer have a problem with 550 tds and an undetectably high ph lvl. Cardinal shrimp have recently caught my eye. I'm thinking of dedicating a 10 gallon to them. It's been up a week with 53 watts of light, sand/gravel sub, Eheim 2211 with 2213 prop (more flow), and some anacharis. As far as I know, having the tank cycle for awhile and a good amount of rocks/crushed coral would complete the tank for cardinals. If anyone who has/is keeping them can say their tank/water specs, I'd appreciate it.

I suppose if you can raise the hardness a lot and keep it hot.

I currently breed them. It's very important to keep the water temp pretty warm. I keep my at 80, but 78 to 82 is good. My water is as follows:

Temp: 80 degrees
pH: 7.8
TDS: 200
GH: 8 / 160 ppm
KH: 7 / 70 ppm

I'm very fortunate, as they are very healthy and have never stopped breeding.

Awesome, thanks. Any ideas on how I can raise KH?

Temperature shouldn't be a problem. Just haven't put the heater in yet. That was my main problem with CRS/OEBT, the tank temps would hit 82 in the middle of summer, without a heater!

People are using Salty Shrimp Sulawesi Mineral.

If you just want to raise KH you can use baking soda. Salty Shrimp Sulawesi Mineral is great if you are starting with RO water since it adds everything you need.

Right, thanks.

One more question, is it safe to assume that since my KH is low out of the tap, that GH will also be low or somewhere around that ballpark?

Sorry to rain on your parade, but at least 9 out of 10 people fail when trying to use tap water for these shrimp. Save your time and money and don't make the same mistake that I made when I first tried keeping them.

Your best bet is to use RO water or distilled water from the Grocery store with Salty Shrimp Sulawesi Mineral 7.5 or 8.5. I use 8.5 and my params are pH 8.5, GH 7-8, temp 82, and TDS 150-180. Mine are breeding like crazy in those params.

Good luck!

Thanks a lot! I suppose it takes a lot of the guessing out of things, even though the stuff isn't cheap.

What are your reasons for choosing 8.5 rather than 7.5?

Also, how exactly do you mix the stuff?

The 7.5 is much easier to mix the the 8.5 which is harder to get to dissolve properly. The 8.5 was designed for the harder to breed Sulawesi shrimp and the cardinals do well in both the 7.5 and 8.5.

I use the 7.5, works great, but my pH is over 8 even though it's called 7.5, haha.

Most critical part is keeping them over 80 degrees.

Sounds good, heat is easy to provide!

What is your kh and gh? I suppose you would have to pay little attention to these while using salty shrimp, correct?

How often do you/should I perform water changes?

I've never done a water change in over a year for my cardinals. And there's hundreds in there.

My gh is around 8, I don't know my kh.

I do have to top off quite frequently because of the high temps, even though I have a cover on the tank.

Here's a video

Over a year?!?! That contradicts everything I've read so far, lol. Do you know your TDS? You top off with RO water correct?

I'll certainly be interested in some of your shrimp once my tank is cycled.

Yah, over a year, haha, and it's only because it's the top tank on this rack, and my water change tube doesn't reach it, and I'm really not keen on manually removing the water.

But it seems to work fine for the shrimp, I've never had a problem breeding them!

Last i checked the tds it was around 450.

I use tap water for top offs, but my tap is basically RO (tds around 10 this time of year)

I have another 20 gallon tank I'm thinking about converting over to sulawesi so I can double my breeding, but I have like 15 pounds of akadama to pull out of it, and I haven't felt like getting muddy.
