Adding a product like that to lower the pH is not a good idea. It is unlikely to lower the pH except possibly temporarily, so you would be constantly adding more and more. And pH is not a critical parameter. If you are using your tap water you can assume the fish store where you got the fish is also using that tap water, so the fish are acclimated to the water. Finally, many water companies add something to the water to raise the pH to protect the copper pipes in people's homes from eroding away, but that usually only temporarily raises the pH. If you let the water stand for several hours the pH will probably drop.

 

When I said water I meant tank water . Heh sorry for the confusion. And that was after a week. I was just trying to get it down for my cories . They are bumps on a log. Except at night.

api ph down is an awful product. not to mention that tampering with your ph usually causes more harm to your fish than having a "high" ph does. what type fish do you plan on keeping? unless you are keeping wild caught fish from the amazon, chances are the storebought fish you may get are already used to this type water. a constant ph is way more important than a perfect 7.0 ph.

if you are hell bent on lowering your ph, adding co2 (injected) and controlling it that way. or add your fish and enjoy how wonderfully they do in your "high" ph water.

think of what may be causing this high ph also, does your wife have rock in her tank, what type substrate?

Umm don't have a wife it's my tank lol. Only thing I can think of is the water softener . Which If it's sofening it , it must be really high to start with. And can't get water anywhere in my house without it being sofented. All the rocks in the tank were tested so idk. Thanks for the opinions guys

Water from a water softener is not good water for an aquarium. It will contain lots of sodium ions which were substituted for calcium and magnesium ions. Since softened water is not good for watering plants either, almost all water softener installations are in the hot water plumbing only. The hose bibs outdoors will almost always be unsoftened water. If you want to use the softened water, buy a reverse osmosis filter, and use it before putting the water in the tank. Softened water doesn't clog up the reverse osmosis filters as much as unsoftened water does.

 

Noooooooo!!!!!!!!

Go RO or just deal with your ph. Altering your ph with that product is just a bad idea.
