Alright, this thought was born from the fact that my betta's heater broke last night and I found him half frozen this morning. He is currently in plastic box, jury rigged as a refugium in my 75 gal cichlid tank. Obviously not ideal as my Jack Dempsey had taken an interest in him.
Anyhow, took a few minutes on sketchup to dream up this idea.
It is basicly a built in filter with a refugium (I'm not sure what else to call it) incorporated.
From the front:
Basically will just look like a black background. Water flows in from the top right and out through a power head at the bottom left. The middle is clear glass to allow for viewing of a new betta home. I have also added shelves to help interfere with a strong current and give him a resting place but I am not sure that 16"x4"x20" is an ideal home for a betta. I could extend it from 4" to 6" in that one part what do you think?
Showing the filter. I have the power head pushing water out and the heater over on the right. I am happy with the powerhead but any thoughts on a better location for the heater?
I know its not an ideal place just from the whole heat rises fact but hearing from people who have DIY filters would be good. I am thinking that the power head will be stronger than the heat and pull the water back down.
So the plan takes up four inches at the back of the tank which I'm cool with and there is a shelf at the top for plants to grow out emersed.
3/4 view sort of to give better perspective.
So any thoughts on how it might not work?
