Never used an air stone... really? A bubbler? Not sure about that. Don't want excessive algae

So I do have 2 power heads. The water oxygen search for my fish is now gone like clockwork. Fish are acting normal again. Maybe it makes sense that after a long over due change... the prime wears of and there's a bad adjustment period. I'm taking this info to heart and will Gradually increase my water changes. Will adding pura complete make any difference? I've had my tank for long time with little issue. Yet I logged on so I can learn more and give my fish a healthy tank.
