This goldfish tank is filled and surrounded by my late mother’s knick-knacks, and sits upon her credenza from my childhood home in Baker City where it catches the early morning sunlight. It also has an RGB LED light on top so looks spectacular at night.
When you sit and watch the fish in this tank, the combination of sun rays and seeing outdoors right through the tank make it seem like the fish are just floating in air.
When I first moved this tank to the window, it would bloom algae within three days of a good cleaning, and the glass would be impossible to see-through. When I switched to a Marineland C-220 whisper-silent canister filter, the algae blooms stopped and the water became very clear. When I added the (kind of noisy) air bubbler, within three days the water was crystal clear, and has stayed that way ever since. Even the growth on the ceramic pig has stopped, and that used to turn completely green.
It took many months to get this healthy ecosystem running smoothly. Time will tell if this new system can maintain the clarity.
