What is this haze and can I get rid of it?

[Orca1]

I recently obtained a 120g tank from a friend of mine. In one the tank's corners, I have a haze that I can't get off. I've already tried some white vinegar and a new razor but I've been completely unsuccessful at removing it. I know there are some scratches in the same area which I'm not really concerned about, but the haze is really annoying me.

I know that the tank was used as a f/w cichlid tank prior to me getting it.

Any suggestions/recommendations would be greatly appreciated.

Here's a pic....sorry if it's a little blurry.

My tank has a similar haze over the whole front that appears to be calcium but it doesn't come off either my solution is buying a new tank I'm tired of not seeing the best colors through the front but the side of my corals... Sorry.. My 180 was also a cichlid tank first.. My 125 sump looks clearer than my display..

Thanks for the reply Bob 1000. I was hoping it wouldn't come down to that. Since I got the tank for a very reasonable amount I'm going to most likely hid it with some creative aquascaping.

One friend of mine told me to use a product called ZUD I believe. Another plumber friend of mine told me to try CLR. Although these products may remove the haze I'm worried about leaving chemical residues behind.

Has anyone ever heard of or ever used these products?

I would try a bunch of solvents. Vinegar didn't work so go the other way, try lye lol. Nail polish remover? Wood Sander?Stronger acid?

I know people with freshwater tanks who have bad snail infestations(apparently the buggers are almost invincible) Completely drain there tanks and fill them with bleach. Im guessing any chemical is fine as long as you wash it out and it doesn't break down the sealant.

Thanks guys......

Thankfully, the tank is still bone dry. I'm going to try a number of different products.....maybe even a buffing wheel if it comes down to it. I can easily bring the tank into the back yard and give it an extra thorough cleaning after I use any kind of crazy chemical. Hopefully something will work.

It may well be a poor idea to start using all sorts of different chemicals to get rid of the haze. You'd never be 100% sure that you get them back out of the tank.

Is the haze on the inside or outside of the glass?

What angle is that pic taken from?

When you tried the vinegar - what did you do? Did you lay the tank on it's side (?..still confused about the orientation of the pic) and allow it to soak (as in 'puddle' over the area) for several hours? You might want to try that first as it is the least dangerous 'fluid' you can clean a tank with (other than water of course! )

I wouldn't use Zud, it's like Comet and will scratch the glass, as will a number of the other suggestions. I also woulnd't put CLR within a mile of a tank that will become a SW reef!

Is there a chance that the cloudy area can be placed towards the rear of the tank where eventually Coraline algae will eventually cover it?

Razor blade? you could try some 2000 grit sand paper sand wet

clean tank with vinegar afterward

KathyC.....

The haze is on the inside of the tank. I took the picture from about 8" away angling up towards lighting. I highly doubt that this tank will ever become a reef tank. It's going to become my native marine fish tank for my living room. I'm new to the whole s/w tank scene and want to start off with a nano in my bedroom for my first reef tank.

I didn't lay the tank on its side when I did my initial vinegar cleaning....but I'll certainly try that tomorrow afternoon after work. That sounds like a good idea for many reasons. I can let the vinegar sit on the haze for a while and it will give me a little added leverage while scrubbing. I'll make sure that I put a blanket under the tank to prevent further damage.

Frogman....

I really like your 2000 grit sand paper idea. If all of my other attempts fail, I'll certainly do that. I actually have some still in its package from when I used to mess around with auto body repairs (one of my ex-hobbies).

Do you think that the Eagle1 would leave some residues that could possibly harm my marine life in the future?

Thank you both for your great ideas! This is my first day posting on this site and I'm soooo very happy that I did!

ROFLMAO wood sander, nail polish remover, sand paper, strong acids... Only if you plan on making it a dry tank that you just want to look at empty with teddy bear fish in it..
If you do try some of these let me know how it turns out.. I would just go with a long soak in a lot of vinegar to water solution..
Best of luck with the haze man.. ZUD,,lmao..

sounds and looks like mineral/algae deposits. but its a wierd pattern and place for it. Lay it on its side and let it soak in water for a few hours then take a razor to it. I was unable to get the stuff off mine untill i soaked it in my cichlid tank.

Its either that or the rocks rubbing on the glass if he had any laying on that side.

I dont think so I would read the contents compound like that is usually water fine pumice I would also clean the tank with a vinegar water solution
