Annual trip to Edward Hospital - half cylinder tank

Princess Trainer
I look at this tank every time I go by the hospital. It's a nice size but it's not really a great looking tank. Some deep scratches on the inside and there's not a lot of coral variety. It has looked worse in the past. A few yellow tangs, hippo tang, three sets of clowns (Wyoming, Darwin, regular). I didn't see much of a cleaning crew except for a few Turbos and one peppermint shrimp. Two Koralia (?) power heads for flow and a sump that was locked out of sight. It could be such a great tank.

My husband works there, so when I suggested a reef for the house... this was what immediately sprang to mind. I've spent the last month trying to convince him that we can do better!

I told my husband about this thread and he had a question some of you guys might be able to answer:
Why is it scratched all to hell from the inside? Is Acrylic so soft that the inhabitants are doing that damage?

It's a guess at best, but most likely due to lack of frequent cleaning. At some point the inside was in dire need of a heavy cleaning and the person tasked with the chore gave up on acrylic safe clening methods. They ended up using a stainless steel scraper and tore up the soft material.
 
When removing algae, people will scrape it off with things that are harder than the acrylic and end up scratching it. You can also bump it with the rockwork.
Acrylic's big advantage is it is super clear and easier to bend into unique shapes, but glass is so much harder and less likely to scratch.
