I love that fish room, so nice to have it bright and airy like that with all those windows. My current one and all my previous ones have been dark, dingy basement rooms, few or no windows. Yours is much more cheerful. I hope you have brought in a nice easy chair to relax and watch the fish from. Two more words to make it the perfect fish room: bar fridge.
You also have some terrific DIY projects on the go, and a bunch of nice healthy well-kept fish. The icing on the cake: fetching an aquarium sump on a bike! Bravo!
Looking forward to more updates.
