How is your return plumbed?My eel has never gone down the return - pretty unlikely.

I have 3/4 locline nozzles so i can direct flow and the reduction is minimal.
I couldnt imagine hard plumbing the return nozzles inside the tank lol. My snails are even gonna have fun with these huge locline holes lol.
Current tank has the locline fan sweepers and i still have to dial back my pump to half speed.
