So i have a fish tank with 3 needle nose gar, 1 firemouth and 4 bicher eels and i cant seem to get my PH to a good solid 6.8 or 7.0 ive tried baking soda, water changes and i cant seem to figure out what the problem is. and ideas what is wrong or what i can do?

its 6.0, but it might be lower. when i did the test it was yellow. also the tank is a 20 gal long
Your pH is 6.0 right? Can you find out the carbonate hardness (KH) of your water? If this is really low, it will affect your pH, causing it to be fixed at a low level. Do you have driftwood in your tank?
 
There is a relationship between the two. When dkh is low it's very hard to keep ph up. Also the sodium bicarbonate, needs to be added with every water change after your ph is stabilized. You might think of adding a more permanent buffer like crushed coral. If you decide to try this I would start by adding small amounts of it at a time and let it be for a week or so. Check pH often and add more if needed. Don't put too much too fast because you don't want your pH too high. Some would disagree with this method as there are always different schools of thought but I have used this method before with success. Generally I use this for African Cichlid tanks but since then I have moved to a special substrate for them I think it's made by Eco-Complete or something close to that.

Is your pH 6.0 or your dkh?

what exactly is your dkh (hardness)

dkH or kH = Carbonate Hardness or alkalinity... not to be confused with your gH (general hardness) which is what people usually refer to as "hardness". "Hardness" being the levels commonly seen as: soft, hard, etc.

So make sure you measure your dKh (aka Kh or alkalinity), although they are all effected when each parameter changes. Kinda like Ohms law, but for water.
