Cleaning a acrylic tank with calcite deposits

[sap]

I am going to be picking up a used acrylic reeftank and the owner has said back wall is covered in calcite. Is this something easily removed with a little elbow grease and maybe a pressure washer? I have a 180g glass that was formerly a saltwater setup and it had some protien etching on the outside of the glass and it was not removable, causing me to be a little hesitant in purchasing this used setup.

Even if it is eched...I "think", with acrylic, you can polish it out...

again I "think"

maybe someone who knows will chime in.

you can use Clr.....leave it to soak......and with some elbow grease it will come off.

this is a really nice custom setup, coming from a guy that lives in Preston Hollow in North Dallas, it is one of those I want it out of here type of deals but if i cant remove it I dont want it.

NO NO NO NO NO NO NO....

1. Lots of vinegar no bleach....
2. Get 2 scrapers long and short $25 total but are worth it, I did only the short and still wish I would have got the longer.
3. It is not THAT bad I did my 180g in probably 2 hours of actual work.
4. I can give you the address to an acrylic shop that sells the liquid abrasion crap to clean it up for pretty cheap. You can get the sand paper at Elliot's hardware for about $1.75 a sheet. I am starting this part of the process tonight....

Doing it over a period of a couple days seemed to help also.

Starting out was tough and I thought everyone who said "It's no big deal" were freaking insane. Day 2 was pretty easy day 3 easier and so on. I did like 30 minutes each day the last day I did probably 50% of the tank.

I found less water the better. I used a rag (no a paper towel) and spray bottle with 50% water and vinegar worked well. I tried a hose as was recommended but it made a big mess and did not seem to work.

If you do not like the scratches:

1. Get a palm sander
2. Get a lot of wet/dry sand paper (1000, 2000, 3000)
3. Get a spray bottle of vinegar and water
4. Spray sand, spray sand, spray sand it should turn white, clean it up spray and sand till it goes clear again and clean.
5. Polish

Works pretty good not real quick but works great.
