How clean acrylic corners in the deep

[Achilles Torben]

Hey guys

I read here about mighty magnet and buy it. It works very well and I reduce time to clean the tank. But I have problems to clean corners in the deep. My tank is more than 1 meter deep. The first half of the deep I reach by hand and a 10cm x10cm piece of acrylic. But how I can easily clean the deep without dive into the tank. You know something that works for me?

Thanks and greetings

Torben
