Nero Pump Question

[chaoticreefer]

Hi everyone,
I am getting tired of dealing with my MP40s every few weeks, one or the other. They get knocked off constantly on their own. Each time, I have to acid bath the wet side and try to get them aligned again. And they don't always get aligned on first try, even when I start slow at 10% on fire up and only increase it by 10% at a time.

So my question is...do Neros get knocked off like Vortechs do? I was eyeing Nero 3 since I only run my Vortechs at 40%, but seems like no one has them in stock, so I am considering Nero 5s.

Edit: correcting grammar

I’ve had a Nero 3 for almost 1 year and Nero 5 for 5 months and they have never fell off. I don’t see how this could happen as the magnets are strong.

I have the Mp40 and the Nero, don’t have issues with either one getting knocked off… how thick is your glass?
