That’s sounds pretty cool indeed.Sounds nice. I am getting a 120p and want to drilled for an overflow to a sump in the garage then back to the tank but use Lilly pipes for the returns instead of the lock lines. Have talked to the fellows at Reef
Synergy and they are making me a white overflow with Stainless steel mesh to keep the shrimp out of the sump. Then I can use a Frosty film for the background of the tank.
How much flow can you push through the lily pipes?
Something to keep in mind if you need more powerful pumps pumping water from the garage . The bigger ones have 3/4”+ connections while lilies are 1/2”? Maybe you need reducers or bigger lily pipes.
They do make white locline. Just sayin
