I’ve gotten a great deal of help with my previous post but I’m hoping maybe this is a little more simple to answer. While I was having my tank maintenanced by someone else (due to working so much out of town) they built this ten gallon sump for my 75 gal tank. I reacently added a light and chateo. With how it is built I’m unsure of where the water level needs to be and dumb me never thought to ask. I’m hoping with the pics you can see how it’s built and guide me to the correct water level for it to function as it should. Thank you
