The only change I made was the addition of a bristlenosed pleco that was given to us from my Nephew who has a breeding pair.
The filter is a Fluval U2 that I clean out the filters about once a month. I don’t really do much for water changes. I take out a few gallons, just enough to rinse out the filters. The Air stone is a 4 inch bar that is a carry over from when I was cycling the tank. My wife likes the bubbles.
Here are my light values. I probably should change them a bit.
