Answer 1

Mine used to like to hang around 7.8. The best thing I've found to use is kalkwasser. This is a white powder that you mix yourself. It's highly caustic, so be careful when handling, and if you get any on your skin, brush (rather than wash) it off.

All you need to do is mix a spoonful or two with water in a clean soda bottle (don't worry about the exact amount - any excess will settle to the bottom) and add in small doses (I use a capful at a time for a 10 gallon tank) and only add about 1-2 capfuls a day per 10 gallons till you get the pH where you want it. Then, you only need to add about a capful per 5 gallons of replacement water when you do a water change or top off. Be sure to add the water to the tank slowly. I use another soda bottle with airline tubing and a flow valve to dose the tank - fill the bottle with freshwater to top off for evaporation, and add a capful of the kalkwasser mix to this - the water siphons into my filter and takes a while to empty so the change is more gradual.

Once you get close to the bottom of your "mixing" bottle, just add more water and more of the kalkwasser powder will dissolve.
