Let you know about Mr Clean in 3 weeks. The thing with acrylics is that you can use normal cloth to wipe. It will cause scratches over time.
Seems like Mr Clean is the only sponge that cleans with good review from reefers in US.
As for scratch removers, Novus does a pretty good job with light scratches.
I will try and post a demo later. Ian from I-aquatic recommended these for his acrylics too.
for my cabinet, no nothing special inside. Just a simple 1.5 ft nano. No complicated stuff.
using it just to house my chiller and electricals basically. maybe find a way to house the ato tank.
