So build has been derailed... big time I think...

I have been bothered by the coralline algae stains on the glass... When I bought the tank, It was covered in coralline algae. When I got the tank in place I was able to fill it and razorblade all of it off the glass without a problem but mineral deposits left by the coralline algae have etched the glass...


side view, uggghh!


front view of inside of side pane...


other side view, near the door...

The front pane is not as bad, I'm assuming it was clean more often than the sides, not allowing the mineral deposits to dig in. I have never heard of this and didn't think it would be a problem, but now I'm looking at scraping the **** tank!

I did some research and tried to remove it with acetic acid/scotchbrite (non scratch) in a small section and it didn't budge. Then I stepped up to 100% muratic acid with regular scotchbrite pad and it still would not come off. This was a small section in the back pane. The starfire panes are etched much deeper so I am at a loss...

beware... keep that glass maintenance up...

Wow that is horrible news. I can't believe that. Getting used tanks is always a risk

Maybe it might be better to order a brand new tank and get exactly what u wanted, and add some cool features. Like external overflow or something like that. So at least it will be worth getting a new tank.

that sucks! i had no idea it could do that.. :(
Tell me about it, I've been so bummed about it so today I drained the tank to try to clean it... now I'm even more depressed...
wow coraline algae can do that. thats a first for me
I had no idea either... I had no problems like this before but I've always kept my tanks pretty clean.

Yeah, I knew it was risk, especially when I couldn't inspect the tank thoroughly before buying. I was hoping there were no scratches or gouges, but had no idea this would be hiding underneath...
Thought I was saving big with a used tank, now I'll probably be paying a premium for a new one.... ahhhh... so upset...

all is not lost though. I'm pretty sure they make glass polishing / cutting compounds for the car detailers.

I'll ask my friend for his opinion. he has been to like a zillion training sessions now at Meguiar's and can turn a faded turd of a car into a shiny gem.

I feel ya. Buying used always runs that risk

Take this as a lesson for everybody buying a used tank. ALWAYS have the seller fully clean the tank. That way it can be fully inspected.


Such a bummer man.

I know it's not cheap. I had a company quote me to get some graffiti off a few of the windows at my store...was pretty pricey

haven't heard back from him yet, but i don't remember it being pricey when he talked to me about it.
Maybe it's a different process or something. Apparently these took some "special polishers" or what not. I know a few people who have used them, and supposedly the windows look brand new when their done. BUT idk how it would work on a fish tank. At this point, might be time to cut your losses and get a new one. :/

That's a big tank to just "cut your loss" on.

There's no special polishers that I'm aware of. Just dual action polishers. Harbor freight even sells them for 50 bucks. The trick is knowing how to use it.

Magic eraser... Like a soft sponge. I tried this with tank filled. Definitely don't have to worry about scratches, but didn't touch the stains.

Conc. White vinegar (I left 3 gallons in a Bucket after I used it on some equipment, it concentrated down to half a gallon). I used this with no scratch scothbrite pad... More abrasive but no luck.

Muratic acid... Left over new bottle I used to wash my dry rock. This stuff is potent! I didn't even dilute it... Applied some with a qtip to small area, let it sit. Applied more, scrubbed with regular scothbrite pad. Even more abrasive, it actually scratched the glass a bit, but stain is still there...

I can see them in the pictures and the tank is partially filled. I couldnt live with those stains.

Terry, Im sorry that you are having to go through this hiccup. You were going at a nice build speed too.

It is very noticeable with water in it. I'm pretty picky about blemishes, but this is way beyond any blemishes. Thing is, I don't want to build my reef and later have to deal with these issues. Gonna have to take care of it from the start. That's why I've been kinda stalled here.
