Good potential, but based on my experience with IQ4, u will have to be very careful with the magnet cleaner (using 2 little fishes nanomag for acrylic and glass tank) on the surface, any sand caught between the acrylic surface and your magnet cleaner... will be nightmare... I'd already got a long scratch, lucky was on the outside and managed to use acrylic polisher to remove the scratch...
One more suggestion for you is to avoid placing any LR or rics or anything against the inner acrylic surface, reason being also the above-mentioned as well as difficult to manoeuvrings the magnet cleaner when removing any diatoms/algae ... well, just my experience so far to share with you and hope u dun mind my frankness.
Cheers...
