View Full Version : Murky water

05/19/2016, 09:25 PM
Having an issue with murky water. This is a brand new tank so water should be crystal clear, and it is outside the tank so I am baffled....

(3) of the (4) sides are low iron, the one to the right which faces the wall is standard glass, didn't see the need to make that low iron, the glass braces on top of the tank are regular glass and the bottom of the tank is regular glass, which is irrelevant since the bottoms is all covered with sand.

If you look, you can see from one side of the tank to the other along the long side, but if you try to see from the short side across the the other two panes you can't, in fact you get a little mirror effect!

And the water, to me, appears to have a green hue...what gives?!

Can anyone help me find out what's causing this? I have already emptied the tank once and made clean ro/di water which again, outside the tank it's clear as can be. So obviously it has to do with the glass but I don't get it, it's clear looking at it which sides are low iron and which isn't so I'm lost.

If you look at the first and last two pics you will see that you are seeing reflections like if the glass was a mirror instead of seeing across like you do in the second pic.

Any thoughts?

You just set it up? I'd guess something from the rock or sand. Did you rinse them before putting them in?

Should settle over time. I'd use filter socks and carbon to mechanically remove it so that it's not being stirred later anytime you touch the sandbed

Edit, wait. It's from the outside? Could be from lighting difference, anytime the tank is darker than the room the glass acts more of a mirror. That could explain the reflection, but murky is a different story. I'd still run carbon/socks and let it go for a bit

Just setup yes but it was doing this without the rocks and sand just empty which I thought would be the reflection from the bottom of the tank not being low iron. You're probably right on all else.

I've just put the filter socks and carbon in the carbon reactor last night so let's see how it fairs out in a few days.

Thanks for the advice.

Yea, reading it again that's just the lighting difference. My tank is all starfire and when the lights are off I can shave in the glass.

Wait for the lights to go on and it will go away

Thanks again

Looks like it was all the initial debris from the rock and sand - after putting the filter socks and letting carbon run for a few days now it's crystal clear.

Try adding some Zeo Coral snow, it will clear this up.

Thanks, the use of GAC and letting it settle for a couple of days did the trick.
