Hello guys :) im planning to purchase my first betta in a few days so I've been lurking around this very helpful site for research. I have a 2.5 Gallon tank, 7.5 watt heater, and planning to purchase a sponge filter. I plan to change the aquarium water using my tap water and it reads around 7.6 PH. I have read that the water should be around 7.0 PH and am wondering what would be the safest/best way to lower the PH of the tank water.
As for the heater, will leaving it plugged in 24/7 cause the tank to overheat? If it does do I put ice cubes it it?
All of the advice and information from you guys has been a great help to me!
