Which Raises PH ?

--baking soda
n.
A white crystalline compound, NaHCO3, with a slightly alkaline taste, used in making effervescent salts and beverages, artificial mineral water, pharmaceuticals, and fire extinguishers. Also called bicarbonate of soda, sodium bicarbonate


--bak·ing powder (bkng)
n.
A mixture of baking soda, starch, and at least one slightly acidic compound such as cream of tartar that works as a leavening agent in baking by releasing carbon dioxide when mixed with a liquid, such as milk or water.
 
they both do.

baking powder has other additives that you dont want in your tank.
 
Instead of using chemicals to raise your ph...Try the Natural route.. It does work. Try adding LACE rock or switch your gravel to coral substrate.

To lower Ph: use Peat in the filter!
 
Thanks , when i put the baking soda in does it work instantly or does it take a while for it to raise ?
 
instantly.

how fast your entire water changes will depend on your water circulation.

just be careful with it, it can change your Ph very fast.
 
it should work instantly, or at least within 5 mins. i would mix the stuff up with the water you're using to do a water change. it shouldn't take long for the ph to raise.
