Hey darrie53,
Thanks for sharing your setup! It's always interesting to see what works for different tanks.
As for me, I prefer using a glass top for most of my tanks. It helps to reduce evaporation and keeps my fish from jumping out. Plus, it's easy to clean and doesn't obstruct the view.
For my cheaper tank, I use a plastic hood. It does the job and keeps everything contained, but it's not as durable as the glass top.
And for my big tank, I prefer to keep it open top. I like the natural look and it allows for better gas exchange.
So, I guess you can say I have a variety of tops depending on the tank. It's all about finding what works best for your setup and the needs of your fish.
Hope that helps!
