If its below 4 degrees I'd add half cup crushed coral, dolomite etc to your filter to stabilize it.

These swings are really not good for your fish there and really stress them out, which in return makes them unhealthy. So I'd def recommend a more natural approach/ permanent then the weekly chem feeding there.

My tap is 6.8 KH 1 and all tanks are stable with KH's 4-5 and pH's of 7.2-7.6...it is possible even with soft water.

do you have more aeration in this tank?

BTW Platys like hard, alkaline water 7.5PH.

In this case I would not add coral or dolomite to the filter, it will make things worse. I use dolomite and crushed coral to raise my hardness and pH slightly, and using for example dolomite gravel as I did years ago in a livebearer tank kept the pH in the high 7's for livebearers when the taop water was 6 in pH and very soft.

Previous advice was accurate, let this tank stay at 7.6 and keep livebearers in it, they will do very well in slightly basic (alkaline) water. Move the corydoras to one of the tanks with lower pH. In no case keep fussing with attempts to adjust the pH, the chemicals will stress out the fish as Angel and iamntbatman said, and that is worse long-term. Plus, as you've seen, they do not work.

Why would it make what worst in the tank?
If he/ she has a super low KH (still waiting to see readings there) its no wonder the pH bounces around like that, stabilizing the KH would stabilize the pH....I can't follow you there right now, I'm sorry.

What I was trying to say was that adding more calcareous material will further increase the pH. While adding calcium and magnesium will increase the carbonate hardness, it will at the same time raise the hardness (and pH correspondingly). The two are connected. If the intent is to keep the pH lower, this is not going to help. Obviously something in the present tank is adding mineral to the water; let it do so unchecked, and then keep suitable fish in the tank, since the live bearers are there and would appreciate this more.

Hi y'all! Thanks for all your terrific input! I really appreciate it Well,i decided to take the more "wait and see" route and keep testing my water. I still do a 1/3 water change every week,like I do with my other tanks. No probs with them!! But, this one tank is still doing it's silly pH thang! I just decided to do the leave'er be and just keep livebearers (platys) in it...took the poor little corys out and put them into another tank.
I took everything out of this weird 20L,tested every item...no fizzing,and added each item back into tank one at a time...testing the water each time...nothing! Until everything was back in place!!! Back to 7.6 again!! I gotta laugh here...the only thing that I didn't check outright was the tank itself,ya know,with the water out of it! But,I'm done...just gonna have livebearers in it!!
Now,kinda new question...are there ANY bottom feeders that do well in a 7.6pH tank???

So you have several set up tanks right?
What's you pH &KH from tap vs this very named tank here vs the other tanks you have?

Whenever I have various set up's going at once, no matter how I set it up exactly the same EACH & EVERY tank after its cycled AND starts establishing has their own parameters.
Reason I'm asking this is because I don't think your tank there is done balancing itself out just yet.

Take Bronze Cory's as example they'll do fine from pH 6.5-7.5 and any hardness under 20degrees...IMO these would work for you. I had them in tanks (when I lived having hard water) with pH varying between the tanks from 7.6-7.8 and they were just healthy lil buggers.

Hello,

If you are interested, here is some info on water chemistry: Water Chemistry for New Aquarists (Taken From MOA's Keeping Fish) (MOA's: How Many Fish?, Stocking Freshwater Aquariums).

The above link referrences an article that describes the relationship between hardness, pH, and alkalinity.
