ph testing

[loaching]

i have a 2ft well planted tank with 14 neons, 4 cardinal tetras, 6 white clouds, 2 mollies, 4 dwarf gourami's, 2 peppered catfish, 5 widow tetras and a yabby thats a few months old.
i bought a ph test kit but no matter how much sodium biphosphate i put in to make it more acidic it always comes out about 7.2. 7 being neutral.
any advice for changing ph.

Hi Loaching, I'm sure I won't be the only one to advise you DON'T mess about with your PH, my PH is 7.8 and my fish are fine. If yours is 7.2 ( which I think is fine anyway ) then the PH of your LFS is also 7.2. Most fish can adapt to a range of PH, so if I were you I'd stick with what you got and wouldn't go around adding chemicals to your tank. Just my opinion but I hope it helps.

can i ask why you want to lower your ph in the first place?
