hello all

I've been reading a few articles today and I've constantly read that using pH down is a bad idea.

I have been using it for the past few months and I have successfully dropped my pH down to 6.6

my KH is 3.36dH
my GH is 3.36dH

I have a small piece of driftwood in my tank but it doenst leak tannins so I'm assuming it doent lower the pH

Can you please tell me why using pH down is a bad idea??
Are there chemicals in it that are deadly?
does it make the tank water cloudy?

I have no co2 being injected

pH down is a chemical that lowers the pH, but doesn't last long in the water, so the pH just goes back up, thus creating a fluctuation.

I second Huntress's thoughts on pH down causing the 'yo-yo' effect.

To answer your other questions, the danger in pH down is the 'yo-yo' effect. Quickly changing pH is stressful to fish. Stress can lower a fishes immunity.

As far as the chemicals in it being deadly, they aren't.

Cloudy water can be a side effect of some pH lowering products since a large number of them contain phosphates. Especially when added to water with high nitrates, phosphates can lead to both cloudy water and algae problems.

well my pH has stayed constant over the past few months.

I thought that if your KH was low then there was not enough buffering capacity to raise the pH back up again.

My fish seem healthy so should I continue using it? and if not what should I do instead
