TheClark Posted October 19, 2016 Share Posted October 19, 2016 Hey AllMy son's acyrlic tank has hazing inside of it.I don't think this is crazing, but am not sure. It is basically a foggy look to portions of each side of the acrylic. The pattern is random but tends to be more towards the bottom and back of the tank.I cannot scrape it off with anything including acrylic scrapers, dobie pads etc.Here is a phone picIt almost seems to be micro scratches but I cannot tell. I need to get out the macro lense and do some closeups I suppose.My gut is telling me the urchins could have done it. There are not even any snails in this tank, just two golf ball sized urchins and a pseudochromis.Has anyone else experienced this?I am thinking of trying micro mesh in tank to see what happens. But it would be nice to get to the root cause as this will be a good sized job.TIA Quote Link to comment Share on other sites More sharing options...
Bevo5 Posted October 19, 2016 Share Posted October 19, 2016 Got any photos? Is it along the seems or on the sides? I'm assuming it's an acrylic tank. Does it look like little tiny cuts or more of a haze over the entire side? If it's along the seams then you've got crazing issues. I'm by no means an expert but I had a very large acrylic tank with some serious crazing issues so I did a lot of research then. In and of itself - depending on how bad and how new the tank is - a small bit of crazing isn't necessarily something to worry about. It became an issue for me because it was happening very fast almost immediately after filling up the tank. So the seams were dynamic and moving under the pressure, which isn't good on a 240g tank. Crazing isn't uncommon at all on acrylic tanks and doesn't necessarily mean it's going to pop. But if you've got crazing along the seams then something is at least moving a little bit under the pressure, which is disconcerting. Acrylic will also get that hazy look as well - which I know can by caused by certain chemicals or additives - but I'm not sure which and why it would only affect a small part of the tank. 1 Quote Link to comment Share on other sites More sharing options...
TheClark Posted October 19, 2016 Author Share Posted October 19, 2016 Thanks Bevo, I will update the original post with some answers to your good questions. it is the weirdest thing I have seen... Quote Link to comment Share on other sites More sharing options...
milesmiles902 Posted October 19, 2016 Share Posted October 19, 2016 Kind of looks like the acrylic got hit by a UV light or the sun. 1 Quote Link to comment Share on other sites More sharing options...
Blue Z Reef Posted October 19, 2016 Share Posted October 19, 2016 Yikes that's weird. It kind of reminds me of what happens if you put rubbing alcohol on acrylic. Seems a bit extreme for an urchin, when I had a pencil urchin it never bothered the acrylic. I know there are some kits people supposedly use in tank for scratch removal, never tried them personally though. Quote Link to comment Share on other sites More sharing options...
TheClark Posted October 19, 2016 Author Share Posted October 19, 2016 Kind of looks like the acrylic got hit by a UV light or the sun. That side of the tank does get sunlight through the window, but it is through a low e window? hmmm... Also the scratching is on the inside. Good leads though, pondering. Yikes that's weird. It kind of reminds me of what happens if you put rubbing alcohol on acrylic. Seems a bit extreme for an urchin, when I had a pencil urchin it never bothered the acrylic. I know there are some kits people supposedly use in tank for scratch removal, never tried them personally though. Yes, it is that kind of a look. Makes no sense to me. Yes, seems extreme for an urchin to me also, Just dumbfounded. Going to try some in tank Micro mesh, reefnjunkie has had good luck with it...

TheClark Posted January 6, 2017 Author Share Posted January 6, 2017 I think I am in the market for a 24x24 cube as his tank is pretty much trashed. So sad :( I never figured out what it was but probably will replace the cheap golf ball sized urchins with something else going forward.

Do you know what additives can cause it? He is running Tropic Marin Balling light. Thanks! Quote Link to comment Share on other sites More sharing options...
Tanuki Posted January 6, 2017 Share Posted January 6, 2017 How old is the acrylic? It looks baked and old, maybe more like cracks than scratches, but hard to say from that photo. I hope its an easy fix 1 Quote Link to comment Share on other sites More sharing options...
wanareef Posted January 6, 2017 Share Posted January 6, 2017 It's the urcins, same in my tank. Some micro mesh and elbow grease will work gl 1 Quote Link to comment Share on other sites More sharing options...
N70SJ Posted January 20, 2017 Share Posted January 20, 2017 You can sand all those scratches out if you want. Takes a little elbow grease. I have sand wet sand paper that goes from 2,000 grit to 20,000 grit. I use it to remove scratches on my planes plexiglass canopy but it works just as good on tanks. 1 Quote Link to comment Share on other sites More sharing options...

TheClark Posted April 13, 2017 Author Share Posted April 13, 2017 There were a few spots I missed or did not hit hard enough on the first pass. Had to go down to 1800 to get rid of them. Looking like new! Quote Link to comment Share on other sites More sharing options...
