OK so i got some pictures, CIMG2321.jpg
This is what the two tanks will look like together, the 1.5g is taller so it will be flowing into the 5g CIMG2322.jpg
This is the area I will cut away and allow water to flow from the taller tank to the lower. I think I will also cut into the 5g tank so the space where the water will flow over will have a splash guard. I will be adding a small lip here to make sure the water all goes into the tank and not drip along the sides of the tanks. CIMG2323.jpg
This corner is where I will be adding a divider and dedicate the corner to snail development. The divider will have a lot of holes as well as vertical slots at the top and bottom to allow surface movement. Still not sure if I need a lot of additional water movement for snails besides the surface CIMG2324.jpg
This is the 1.5 close up, I want the pump to push water in right above the substrate and on the other side will be a plexiglass platform with sand or gravel with a plant. This should slow the current and push the water back toward the right side and upwards towards the waterfall area. I'm hoping that I will be able to have shrimp or a betta in here and the second platform will slow the current enough for a betta. Not sure how much current will be created to get the waterfall going.
Also contemplating cutting the LED fixture in the 1.5 tank and placing it elsewhere as a moon light,
Please let me know what you think of this project, the plexi and weld-on is coming in tomorrow hopefully so i can get to work next weekend cutting and welding.
