300 Gallon Purchase - Manufacturer

Either that, or be more clever. I told my wife I was considering a 12 foot long tank. Then the 300 g that I wanted was a "compromise".

lol! That's what I did with my husband. I wanted an 8' tank, the wall where the 8' tank went is 10' long. So I get everything all measured out and 'inform' him that a 10' tank would fit perfect there. I finally "gave in" and agreed to an 8' tank

I tried the CLR with minimal success. I think I might try a razorblade.

Razor blade and bleach/water is what I use. Be extra careful around the silicone, it's easy to slip and slice the silicone. If it's that hazy cloudiness (seems common with saltwater tanks) it's pretty much etched into the glass. If it's just hard water deposits then a razor should work fine. I've never found a way to get that haze that seems etched into the glass off in used tanks I've bought.

Me either...thats why I dont like to try to buy used ones...but the price is soo tempting.

What about a razor blade and clr...try that

Its not really hazy. Its only on the back of the tank, which is painted black. Its more like shell buildup. I'm guessing that is the calcium. The class isn't really hazie at all. Its pretty crystal clear. The overflows is where most of the deposits remain.

If it's just the back I'd be tempted to say screw it and fill it up...only thing is the deposits might jack around your water chemistry, raise the pH/hardness etc.

If it was a reef tank it might be coraline algae and if thats the case dont waste your time. That stuff is muey hard to get off!

This is what it was. I was able to clean the class without too much trouble. With the overflows I had to use a razor and scrapper. I noticed a bunch of scratches on the overflow from removing the buildup, but it might not be visable once filled up. I'm trying to decide where to put it. I'm thinking garage. I'm kind of worried about putting it in my house since it is used. If it goes in the garage I might make it a tank with local species for now.

I did this and i made sure I stayed away from the silicone. The silicone doesn't look great in all the areas, but I'm thinking that a tank that is only 3 or 4 years old probably doesn't need to be resealed.
