OK so i have this crazy idea to have different levels in a tank! i drew up some pictures to show you guys what im thinking! who knows maybe this is just working better in my mind but im going to try it in a small scale in like a 10 gallon just to see if its plausable then ill move to maybe a 75 gallon and try it! tell me what you guys think or if you have seen anyone do this before! i Think it would be very coool and i will keep you guys updated on how the build go's. any suggestions or comments will be considered! so in the first picture where it says holes drilled in rock to go over pvc im going to get small rock fragments and drill holes through them and stick pvc pipe through them to just support the glass pane! i dont just want to use pvc pipe because i want it to look as natural as possible
