I like my Mega Matrix 150. The silicone gets a bit sloppy where it cant be seen. Built heavily. Glass has better
clarity than my Red Sea 450 did. Only front panel is Crystaline (low iron)
The stand is all wood. Has some over spray, runs in places that can't be seen (In cabinet). The outer finish is OK not great. Paint feels rough like over sprayed. Seems a bit hastily finished but is built well.
Same for the canopy, rough edges on wood cuts where cant be seen. Corner gussets wouldn't let glass tops open all the way.
External overflow is quiet when set up properly.
These are minor issues for a DIY person. The build bones are well done. Price is fair for a semi customizable, quick ship unit. It was packaged well and arrived in 5 days. Stand on top of tank crate all wrapped as 1. Make sure you have somebody to help get stand off tank so you can open and inspect. Takes about 15 minutes. Screwed on top.
For someone who doesn't tinker the Red Sea/Waterbox setups are more polished, complete. But I don't believe the materials used are of the same quality.
I would buy another.
