3) would you recommend it over a hodor koralia evo? I believe the price difference is $15-25, is it worth it?
1 - I'm sure it will be just fine on your thick glass. It's a very strong magnet.
2 & 3 - If you are looking for a wave maker then the price of the hydor wavemaker unit is about the same price as the WP - 25 so it's a very cost efficient alternative. However if you are just looking for a standard powerhead then the Hydor koralia is without a doubt the way to go.
