Wow this thread is way overdue for an update...
Ok so… acrylic sucks. I’ll just say it, it’s horrible. It scratches, it bows, it’s opaque. I remember reading before and not believing it but in the end, it’s true. Any benefit whatsoever to an acrylic tank ends the moment the tank is on the stand. Form there it doesn’t matter how cheap or light it was, its nonstop scratching. You’re ultimately left with the question: do I make big gashes trying to remove the coralline algae, or do I let the algae grow? Either way. Tank's gonna get pretty hard to enjoy
That why, last summer (2021), we reached out t9 glasscages for a custom made 300 gallon aquarium. By August of last year, it had arrived! It took 4 friends and a lot of lifting but we managed to get it right on the same sand as the previous, benefit was this tank was longer and an inch taller bringing the total water volume to 315
