I really want to thank you for cleaning your acrylic...it looks great :thumbsup:...(I did not like seeing the coralline)
Thanks! I didn't like seeing it either although I did get used to it.
Wow that's pretty cool how good that worked. Ultra clear and clean. Nice work.
Thanks!
WOW. What a transfermation. Looks like a brand new tank. Great job.
:beer: :beer: :beer:
I have to admit, I am very very pleased!
I have looked back through but couldn't see this - what reason did you have originally for allowing the coraline to grow? Aesthetics? I'm always curious when I see this.
Also, is this crazing in the joint? (makes for good camouflage for the wrasse!).
The reason it was there is largely because of laziness. Once the stuff starts getting away from you, it's difficult to knock it back. Truth is that I'm pretty used to coraline so it's kind of become something I came to expect. I have had coraline removal pads for a couple years but the coraline had already taken a grip on my viewing panes and it was just so much work that I didn't use them as often as I should have and instead of receding, it continued to grow.
Good eye. That isn't crazing. Fortunately, I have no crazing on this tank even after all these years. What you see is etching on the one side of the tank along the edges. It actually runs around the entire perimeter of that side of the tank but since the tank is drywalled in along the rest of the edges, you can't see it other than the one vertical corner. I've had the tank for over 20 years now and before I moved it to my current home almost 18 years ago, I had the tank up against a window at my previous house. I added an acrylic black back which I siliconed to the outside of the tank on that one 8' side. Behind the black back was a 2" thick foam sheet that was glued to the black piece of acrylic to insulate the tank from the heat of the sun coming through the window. The purpose was both aesthetics and insulation. It served it's purpose at the time.
Unfortunately, the silicone I used to attach the black back to the tank reacted with the tanks acrylic and etched the areas where the bond was. I didn't notice it until I removed the black back when I moved the tank to the new home. Fortunately the etching is only superficial as that acrylic panel is 1.5" thick. As such, there is no structural damage but it is kind of unsightly. I could have sanded and polished it out but it would have left a low point there which would have created some visual distortion when looking into the tank as we would have had to sand well beyond the etched area on the edge to feather it in as the etching is almost 1mm deep. My acrylic fabricator who built the tank for me suggested that it was best just to leave it which I agreed with. Every now and then I think about sanding it out. I've gotten used to it though and it's on the "office side" of the tank which gets less traffic as most of my time is spent in the living room side other than feeding, maintenance and my daily walk arounds. Fortunately you can only see it from the one side and after seeing it for over 18 years, I don't even notice it. Still, I may decide to sand it out at some point in the future provided it wouldn't have any structural impact. The tank is rock solid and visually speaking, it's the only real flaw and it's easy to look past. I obviously wouldn't want to compromise the tanks integrity or create a larger visual flaw that extends into the viewing area.
