Need Help Lowering PH
Hello i'm new to the forums. i was wondering if there is a good way to lower my p.h. currently it is at 8.0. I know it needs to be lowered, but how?

I have recently done a water change with my local fish stores water, so it was not the water. and i also added the usual amount of neutral regulator.
It is a fresh water tank :)

A ph of 8 doesn't necessarily need to be lowered. A stable ph is far mroe important than a specific number for ph.

What fish do you have as this will be important to know. Some fish will actually thrive in this high ph, for example livebearers.

If you do decide to lower it however please stay away from chemicals they are so harmful to the fish. Add a piece of driftwood which will release tannins and bring the ph down. It may make your water look quite brown for a while but this will go away and isn;t harmful to the fish at all, and the process of making it go away can be sped up by adding carbon to your filter. Just remember to remove the carbon if medicating.

I just noticed there that you did a water change using the lfs water. Avoid this if possible because you dont know what diseases/parasites may be present in the water.

Is the neutral regulator a ph altering chemical? Or did you mean water conditioner? Please don't use it if it's a ph altering chemical. This leads to instabilities and can harm and kill your fish.

I use neutral regulator
I use neutral regulator. and my fish are 6 neon tetras and some pink fish (forgot their name) that are crossbred with jellyfish.

So you think it might be best to just let it go on it's own?

Zebra danio. It's now glofish. I don't consider it as crossbred. The genes are somehow spliced with the jellyfish's resulting in a zebra danio with fluorescent colors.

I take it you meant that you used RO water from the store, best water you can get. It should have a natural low PH and help lower yours. I bet you have some decorations like limestone in your substrate or in your rocks that is naturally elevating your PH. As was stated driftwood will help. If you don't want driftwood but have a large canister filter you can add a large amount of peat to the filter. This will quickly lower and stabilize your PH.
