Hmm, well that's curious. Your tank seems to be in order.

Are you serious? If the pH of the tank is 8.0 and the water supply
has a pH of 7.4, each water change administer a pH shock.

Surely not with only a 20% change??

Also, 3 danios are too few. I have 9 of them in my tank. They are
schooling fish. Your danios were probably in a constant state of
unease being in such small number. Since you have a small tank, get
one Gourami or some other solitary fish. Swordtails and platies are
also okay since they don't seems to be too concerned about being in
small numbers.

I originally only had 2 and they were fine, i got another pair because i
thought that this would be nice for the others and as you say they are
schoolers.
It was one of the new pair that died, so now there are three.
I might get another to bring it up to 4 again, but i dont think i will buy
more as i think the tanks already at full capaicity with 3 danios, 3 ghost
shrimp, 2 apple snails and 6 neon tetras, its only a 10 gallon tank.
