Issue with high pH

[BarbsandGobies_expert]

Without divulging your results, It's impossible for us to have any idea of "what's best".

My initial thread told you my carbonate was 300 and my pH 8.4. My Gh is 9 according to my test kit

Ok tanks. PH is irrelevant in that matter. You can have a KH of 90 ppm and PH at 8.2....

There's nearly no amount of KH reducer you can use that will not bounce back to the parameters you have at the moment... You have water Gh is hard and KH is very hard. like livebearers and African cichlids...

If you don't have means to reduce the hardness of the water, orient your choice for harder water fishes in the future.

Agreed. There is no chemical fix, you need to keep hard water fish.
If you decide you want to keep soft water fish RO water is the way to go. I have extremely hard tap water but keep soft water fish. I pretty much tried everything before accepting this. Until then your LFS will no doubt continue to try to sell you water treatements and medications

Okay thanks everyone
