Just out of curiosity, can this be done safely under water in a stocked reef tank?Removing the scratches is not hard, I have buffed many tanks for people. You just need the right equipment to do it properly.
You can scratch with a paper towel. And don't think that acrylic tanks don't break. Seams have been known to bust open with no warnings. But the biggest downside of owning an acrylic tank is cleaning it. At least it used to be until I found Dobie pads. Now, I don't mind it so much.So... kids will be involved, more likely scratches will happen, but a scratch can be buffed where a shatter can't. Are they really that easy to scratch? Someone said they can scratch with a paper towel, I assume that's hyperbole?
I have a probably 15 year old acrylic tank my uncle gave me. Has not yellowed. It was setup for a while by him, then stored for who knows how long, then given to me. I stored it for a few years until my previous tank crashed, i then set it up. Looks great! I polished some with Novus. I can still see some deep scratches, but not bad. If i had taken the time to actually buff the whole thing, it would have been awesome! I don't think I've put any new scratches in, i use only stuff meant for acrylic, and am careful.Ok... so I think I'd prefer glass but it's going to be a pain to get it downstairs. If I go acrylic it's going to be much easier to move and fix if there's an issue, but I'll have to go used and be ready to buff it regularly and use special cleaning pads.
What about yellowing, anyone ever actually seen an acrylic tank yellow?
