From a young age my father and I have worked on various construction projects, fish tanks, welding, computers, etc. I have been working on a special model tank and I'm not sure what I ought to charge for it.
Custom hinged glass lid
4 custom removable dividers(2 opaque and 2 clear)
Custom built sponge filtration system
The set up is what is called a "fish condo". There are two 5 gallon compartments and one 10 gallon. the dividers are removable, and there are two colors that will come with the tank (clear or opaque). The dividers have small custom holes in the top halves to allow water changes of the full tank without removing fish and dividers.
The glass lid has holes to allow oxygen in, and larger holes to allow wires/tubing out. It is divided into 2 parts. You can lift the front 1/4 for feeding without disturbing the light, or lift the whole lid.
The filtration is built by myself and is optimized to take up the least space and electricity by using a gang valve.
Here is a sketch of the tank so far, I don't have pictures of the process just yet but if there's interest I will post them as the project continues!
