should i worry about my kh?

So after a scare of seeing my crypts melting ( thought i killed my cycle while cleaning my canister filter.... False alarm there). Found out its probably the temp since thats the only parameter out of wack. Its sitting at nearly 90* f due to summer... Any ways this investigation reminded me that i have 0dkh. My tap is 0dkh 0dgh and 7.0 ph ( drops to 6.8 sometimes). But ive noticed my tanks ph is much lower. Around 6.5 probably because of my co2. So im thinking of buffering my ph when i do a water changs. Whats your input on this? Only really concered of the ph swing when i do my 70% pwc...

You should check out my Crushed Coral post. It's working quite well.

If you really have 0kH, and add CO2, then the pH should be well under 6.0.

Another suggestion is adding dolomite which is Ca, Mg, and CO3.

The normal PH and that talked about in connection/w CO2 are not the same PH.
It is like AC/DC current. One if changed rapidly can harm fish. The one associated/w CO2 does not.
But the KH is what keeps the first one stable. It should be a minimum of a 3. That is it should take 3 drops in the API test kit to turn it green.
You can use common baking soda to raise it. But do it one measuring spoon at a time and test between at about 1/2 hr intervals. For tanks 29g or less a 1/4 tsp measuring spoon. Larger, about up to 90g a 1/2 tsp measuring spoon. You can go larger on tanks over 90g or it would take forever. Count the number of spoons you use and use that many each time after WC.
But do you have any kind of filter on the water line ?

The shortest distance between any two points is a straight line...in the opposite direction...

My tap usually has a kH=2. But during the rainy/winter season, it can drop to <1. Plants do fine with such a low kH and fish seem to breed/spawn during this time of the year. Also, the API kH test kit should turn from blue to yellow.
