Vortech MP40 magnet strength

[Joe Batt]

I was looking at the MP40QD pumps x2 for my Aquabox 230.6. According to the Vortech calculator 2x MP60QD would be over powered.

However I have been told by a friend that the MP40's magnets are not very strong and would struggle. The glass is 19mm thick.

Anyone have suggestions or comments either way?

They're rated for 3/4" glass (19mm) so I dont see why it wouldn't work. Dont think I've ever read about an issue with them holding when installed properly. With that said, the MP60 can always be turned down and too much flow is rarely enough

I was following the Vortech flow calculator on their site. It was giving too much flow for a mixed reef with 2x MP60. I will also be using 2x Maxspec Gyre 230, so overall in the tank the flow is pretty high even with 2x Mp40
