I have a 2.5 gallon tank with a filter. There is only a betta fish and a sucker fish in it...I received the tank as a gift and don't know much about fish. When I clean my tank I change all the water and completely clean out my gravel without a tube because I am bad at using it. Will the ph change hurt my fish? I've been doing this for a while and they've been fine, but I'm worried I'm not taking the best care of them by doing this.
On the other hand, my water is extremely clean by doing this!

I add a special betta safe liquid to help stabilize the water when I'm done
