Aquarium alkalinity (Dr. John or others may know from chemistry)

I learned after my aquarium already had fish (my dear wife would not wait until the water was tested and ready) that my town has extremely alkaline water. I gave the tank several buffer treatments with sodium biphosphosphate, but the indicator stayed pure blue (too alkaline). After that, I used a couple of ammonia-chlorine treatment tablets that did not have their chemistry on the box--still, pure blue indicator. I do not want to "fill the tank" (exageration) with buffering agents, so I am now thinking I should use some acid. An aquarium problem post elsewhere suggested hydrochloric acid, but I don't know where to get it.

There are many household acids. Vinegar? Salycilicic acid? (i.e. aspirin) What would be effective, without harming the fish?

We had fish a long time ago but I think others on here keep fish now.

Generally, if you suddenly change the pH of your water you could kill the fish - any parameter changes (pH, temperature, hardness etc) need to be changed slowly, and if you have sensitive fish you shouldn't change the pH at all.

One good way is to use peat in your filter, this softens your water and will lower pH or put in bog wood decorations, this is wood preserved in peat so the pH will lower slowly once this is in.

Get some Aquasafe for making tap water "safe" for fish. (Not the maintenance version). There are several other brands, the PetSmart house brand is also pretty good. You can get a small bottle that should last YOU, with a 10 gallon tank, at Walmart for about $4.

I would also suggest that you get a 2.5 gallon jug of spring water at the nearest Walmart (under $5) and do a 25% water change.

Save the jug for refilling and treating tap water for replacing what's lost to evaporation and for doing periodic water changes.

Hope you didn't lose any fish.
