Hi...yep ...that was my original thread. I continue to use the Magic Eraser with no problems at all. It works very well. I have gone so far to shave thin pieces to put on my Mag Float for easy day to day touch ups.
A few notes I'd like to add. Others have said that this will definitely scratch a tank. I have drop the level of my tank 5 inches to allow it to dry to see if it showed any signs of hazing or scratching...there were none...ZERO...NADA..my tank is crystal clear. On another forum there was someone who claimed to mask off part of an "acrylic" ruler and was able to scratch it with the Magic Eraser. I have not been able to find an acrylic ruler locally at the office stores etc to try and duplicate his findings. Plenty of plastic but not acrylic...that being said...my tank is of a MUCH higher quality acrylic than what it available for 50 cents from a dollar store. If there weren't different grades of acrylic then there wouldn't be different prices. Also, I don't think I could use an acrylic polishing kit to buff out an acrylic ruler.
While the Magic Eraser will remove coraline with a little elbow grease, I really would not recommend it. Coraline is a hard deposit and I'm sure pieces of it would stick in the sponge and that might possibly scratch your tank, same as getting a piece of sand or crushed coral caught in the sponge...it would scratch and you would want to blame the sponge..when it was what was caught in it that did the scratching.
Do a good, one time cleaning on the tank then use the sponge as a daily maintenance step. Don't wait 6 months to clean and then moan that it doesn't really work. A little daily swipe saves a lot of time and elbow grease effort in the long run.
Use common sense...if you're not comfortable doing a front pane, try a side pane for a while and see if you are happy with the results.
This is something I researched before I tried it...I should start a "Lazy Reefer" blog with all my short cuts. Some will not want to try this, the decision is of course, theirs.
I started keeping saltwater tanks when I was 16...38 YEARS AGO, and then we used undergravel filters, normal output lighting and could only keep fish.Heck, 38 years ago I was able to buy a Green Sea Turtle that grew to such size I was forced to keep it in the basement in a 2 foot deep kid's pool with a sand filter. Eventually we took a family trip to Clearwater to let it go. (who new back then) The changes made in this industry have been astonishing...but someone has to try things that haven't been tried before to see what works. Could you imagine this hobby without protein skimmers, MH, PC and T5 lighting, sumps, fuges, powerheads, calcium reactors, wavemakers, RO/DI water, test kits, additives, etc. I know I can't.
I am glad to see the dialog this has opened up for the reefing community.
