Try drilling yourself; it's very easy and simple.

I'm scared myself, I've never done this before, and here I am with 450 liters of marine aquarium with living creatures.

Don't take risks. For example, here's a question: how will you cool the crown when drilling a hole in a vertical wall? I don't think anyone would want to drill a 450-liter aquarium for you, especially on a vertical surface.

I feel the same way; I don't dare to do it myself, we need people with experience in such work. I think this is a fairly common problem.

Mario

A piece of foam is inserted into the crown and occasionally dipped in water.

You can practice on unnecessary pieces of glass.

very clearly. but terrrrribly.... if no one responds, then I'll do it myself, of course. it's just that I currently have a PVC pipe overflow, it's very inconvenient, sometimes it gets airlocked, sometimes the suction tube gets clogged. otherwise, it's as easy as pie, I set the level with a corner and that's it.

Contact my friend - Vyacheslav WWS 78 if he is located nearby, I think he won't refuse.

Why is the drilling done from the inside? It seems more convenient from the outside...

Rodney

My aquariums were already filled with water and fish on three-tier stands, and there was only space outside for fittings of 4-5 cm, so I did everything from the inside.
