How many teaspoons of baking soda etc to add to my 75 gallon fish tank to raise the ph is @ 60does i2007-11-24 23:34:44Answers:

1. Get a pH and kH test kit (the liquid kind, not the test strips).

2a. If there are NO fish or plants in the tank: add 5 tablespoons of baking soda to the tank. Check the ph and kh 24 hours later. Repeat daily until the desired ph and kh level is attained.

2b. If there ARE fish or plants in the tank: Dissolve 1 tablespoon of baking soda into a cup of tank water and add it to the tank. Check the ph and kh 24 hours later. Repeat until the desired ph and kh level is attained.

3. Keep track of how much baking soda you added to achieve the level you want. Then replace a percentage of that amount identical to the percentage of water changed out everytime you do a water change (for example if it takes a total of 8 tablespoons, add 2 tablespoons of baking soda everytime you do a 25% water change).

4. Do not drastically increase pH or kh; you'll kill your fish. Baking soda can increase pH to about 8.2 or 8.4.

I put the entire box in my fish tank and the fish started swimming sideways. I guess that was not a good idea.

dissolve soda in water, add some of the mix, wait about one hour and test pH again.add more until you reach correct pH. Do NOT raise pH too quickly, you will kill your fish. The acids you are dealing with are very weak.it will not take much baking soda to do the trick, so start out slow and test, test, test. Good luck

Yes, but I'm not sure of the sanity of adding enough of it to make a difference. The real question is why is the tank water a pH of 6. I've never seen tap water that bad. Also if your tank gradually became acidic due to fish waste raising the pH could be lethal. As your ammonia levels might be a bit high. (As pH goes up the amount ammonia need to kill a fish goes down.)
