Can i change the ph slighty with fish in the tank?

i had 2 angelfish and they died within two days. my ph is 7.5 which i thought wasnt that high.

i was wondering if and how can i change to ph to 7.0 with my fish in the tank. i heard this will kill them but is .5 change fatal or stressful?Can i change the ph slighty with fish in the tank?
It probably won't change all at once the instant you add something, so I wouldn't worry to much about the change, as long as it doesn't happen all the time.

I've used Proper pH 7.0 on all of my tanks for years, and it works perfectly, keeping the pH not only where I want it to be, but also keeping it stable. The only thing I've found is that if you use it with a tank with bogwood, the water will go down an additional .2 to .4 increments, but again it will stay pretty stable. However, you can't use it in a tank with live plants.

Other ways to soften the water and make it more acidic that are more plant friendly include putting in real bogwood or African Mopani Wood, adding peat to the filter or substrate, and mixing in Reverse Osmosis or Distilled water in with tap to reach the desired pH.



I've never kept Angelfish myself, but I think it would be strange for them to die from 7.5 pH. I would look more towards Ammonia or Nitrite levels for a culprit, if you have any reading above 0 ppm that was probably it. Also, if you didn't acclimate them correctly they may have died from shock. Or perhaps they were already sick when you got them? If you have other fish in your tank and you haven't made absolutely sure they were compatible, there might have been aggression too. Angel fish, while large, are very slow moving and ripe targets for fin nippers and bullies.Can i change the ph slighty with fish in the tank?
The pH should be slightly acidic, around 6.5-7.0. You have the right idea of lowering it, but what is the method you're planning on lowering it with? I don't recommend using drops because that will just cause a catastrophe, messing with your water chemistry too much.



The safest way to lower the pH is to do partial water changes using RO water to reduce the buffering. If that's not an option, you could add peat moss/granules into your filter, add driftwood or a Co2 bubbler. Keep in mind that driftwood and peat moss/granules can stain your water a pale yellow colour like tea. It also depends how hard your water is otherwise this method won't be very effective.



Are you sure that your fish died because of the pH? It could've been that they were shocked from the temperature, stressed, or if you just didn't cycle the aquarium properly.
my ph was 5 and now its 7.5 i now how to rais it but not to bring it down

and angel fish prefer 7.5

i got 2

it cant kill them if u change it that much
The pH wasn't what killed your Angels, 7.5 is a pretty average value and they can live in it just fine.



Dont waste your time trying to ';fix'; a non problem.



Check your water for ammonia and did you use water conditioner to remove any chlorine? Those are much more likely reasons for sudden deaths like that.
