OK so i got some pictures,
This is what the two tanks will look like together, the 1.5g is taller so it will be flowing into the 5g
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.
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
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.
