This is lots of help. I’m waiting for delivery of 48x20x24 tank. I have an mp10. Also have a hydro koralia. I want something that’s not going to take up too much space in the tank. I was thinking thinking of going with 2 mp40’s Haven’t really heard anything about the Nero’s aside the million unboxing YouTube videos. And I’ve heard the new gyres are quiet but I’ve heard of maintenance nightmares.
If you plan on keeping the MP10 for that tank, be sure to use the adhesive wire supports. MP10s don’t do so well on anything over 3/8” thick glass.
