Really hard water, need help lowering my Gh

Cassiejh

Hi everyone, I'm new to this.
I've tried lots of threads but nothing really answers my question so thought I might as well just ask myself.
I've had fish for a couple years now with pretty much no problems. But I moved to an area which has very hard water and I've been trying to fix it ever since.
After some research I decided to try using distilled water to balance out the hard tap water. I've been adding it slowly over a few weeks to prevent shocking my fish but there's been no difference. I've used different test kits so I know its not a problem with them and when I test the distilled water on its own the readings are really low. But the Gh in my tank isn't changing. Ph and kh have lowered gradually and are at a nice level now but my Gh is still way too high.
Am I doing somthing wrong or am I an idiot for thinking I can lower the gh this way??
 

LowConductivity

That is the way to go. Dilution is the solution.

How are you measuring?

If the fish are showing no ill effects from the hard water, really no need to adjust.
The breeding of certain fish species might be impaired, but most species of fish can adjust to a wide range of water parameters.

Thats reassuring.
34 litre tank. First 2 weeks I was replacing 2 litres each time but last week I did 5 litres.
I guess if I just keep persevering I will start to see results?

That would explain the lack of results. I'd probably be trying to start at something like 8L distilled/8L tap ( 16L total) for my weekly water changes, and adjust may distilled/tap ratio as required

I’m late to the thread but came across this while searching for help for my high gH.

I did some math and after five water changes at 6% each (your 2L) you would turn over 27% of the water. But at 15% water changes (your 5L) then five water changes would swap out 56%. At the 16L there would only be about 4% of the original water left after five changes!

Hope you are making progress!
