Hello guys i am thinking of pickingnup these 2 used actylic tanks but realy not surw about if it is worth the cleaning or not. I have a novis polish kit i just used on another so no worried about the end result more how to get that nasty algae of the back of the tanks Simple vinegar and water not working for that. I have never let my tanks get that nasty or cleaned any that bad thanks for your time . I know this has been covered a million times cant seem to find the right lost for it thow

Hydrogen peroxide might work. I would leave it though.
 
A really strong vinegar solution should work, but you should fill it up the tank and let it really soak. Maybe even throw in a circulation pump and let it run for a few days. That amount of coralline will not come off without some work.

I'd try vinegar, Fill them up with water, dump a bottle of vinegar in and let it sit. A power head for circulation would help. Should get most of it off.

Like others have said vinegar and water will eventually work it must be in high concentration and allowed to soak. The pump won't hurt either. Depending on tank size I'd say at least a gallon each.
I purchased a 300 that was worse then that two gallons of vinegar and a week later and it came off with little effort. Then the novice stage happened. Then the ex whinned alot and I sold it for a $400 profit. Would have rather had the tank tbh. (Should have sold her)

If soaking with vinegar and a circulation pump does not work you could always start with 400grit wet dry sand paper then 800, 1200, then Novis. I would not want to do it by hand though. A power wet/dry polisher does a really good job on projects like this.
