Just thought I would post this here too.

So I have been using test strips (never again) that told me my Gh was 9, my Kh was 7 and my ph was 7.2. They never really varied from that and I wondered why my values were so weird without adding CO2. Then, I finally broke down and got a freshwater test kit and a separate gh/kh tester. The values it said were: Gh: 11 , Kh: 8 , Ph: 8.6!!! I was so surprised that my shrimp had managed to survive in these conditions at all. They showed no signs of stress such as swimming erratically, sudden death, or trying to climb out. They all just adapted I guess and have even produced eggs but no babies yet. I am taking the ph/gh/kh down slowly by 5 % water changes with water of ph 5.8 and no gh/kh (my tap) every half hour.

What is even more amazing is that my plants haven't all died yet (about 30% had.) That is what alerted me to the fact that something was wrong in the first place.

It must have been building for a while because I add gh+kh up at every water change. I make sure it is the same amount every time and didn't assume there to be anything wrong. This is my biggest mistake with aquaria ever.

Wow that's crazy. I was going to say gradual reduction but you're doing it already. I'd actually slow it down further, maybe only 10% each day.

Are you running an air bubbler? Oxygen saturation can drive up the pH quite a bit. Your tap has no GH/KH? What's the TDS? That sounds like R/O water perfect for Taiwan Bees!

I'm actually pretty surprised the test stripes reported nearly "accurate" gh and kh values :P
Fish Shrimp tanks are like cups of coffee, one is never enough.

Yeah I just recently added a sponge filter to replace a crappy canister. (never buy an API NEXX!) That probably drove it up a lot... My tap params are:

Ph: 6.0~ish
Gh: 0
Kh: 0
TDS: 0

You shouldn't have told me that it is perfect for bees cuz now I have the desire to set up another. I can hear my wallet screaming from the other room

I mean you'd need to mineralize GH up to 6. Do you have a RO system in your house or something? Or that's just straight out of the tap? What city?

Also what substrate? Surprised it went up that high, mine is pretty stable for now.

I have no RO system, no water conditioner or any sort of filter like that now that I think about it... (ewwww...) That is what comes out of the tap. I am considering leaving some in a container overnight to find out if it changes at all. I outside of the town of North East, Maryland. (the boondocks).

I use Flourite in my tanks which seems to have absolutely no buffering capacity. It is a good substrate for plants as I have amazon swords in there that don't need any ferts after 7 months. It is extremely dusty though, and stirs up annoyingly at the slightest disturbance.
