weird tank growth? can anyone help?!

  • We are currently upgrading MFK. thanks! -neo
my mbuna tank did the same when it was newer, i cleaned to much and interupted the water peramters, and it ended up cycling again, my ammonia levels went through the roof. i would check everything nitrite nitrate ammonia, im sure something is messed up, i used safe start by tetra to help it along and had no fish casualties. hope any of this helps, good luck :-)
 
Well, as soil doesn't describe vegetables, neither can an ammonia spike describe that which it sprouted, the white stuff in your tank. Detailed description?
 
it hasen't grown back yet
 
no, i just can't remember in exact detail what it looks like. ill try, it appearse from the current of my filter, it appearse as a little fluf in a certain spot, and after a couple minutes you can see as particles start to fall of, thats where the salt looking specs come in. the particles fall off float/fall down a little lower and starts to disovle into a fog like smear on the glass, not in the water. this spans the whole length of my 6' tank and on only 1 side. when it first sticks the the glass it is about the size of the tip of a pen, then slowly starts to disolve, i need to see it again to get more detail, but if i think of something i missed i will add it in!
 
This sounds like perhaps a salt or gas. If you pour a glass of warm water, does it get bubbles all over the inside? I 'm thinking this may be a dissolved gas from your tap. If it is, I fix mine by filling my buckets in the bathtub so that the splashing aerates the water and releases most of the gas. Then, when I dump the bucket into the tank, I control the flow and hold it at a good frothy splash to release even more bubbles. Then I do get some cloudiness from the HOB as it reenters, but it goes away after a few ours.

Wait, you said you cleaned it off of the sides? Did you actually remove white muck or did it just disappear as you wiped it?
 
im not sure, when i went over it there wasn't a cloud of it leaving the glass or anything, it was there and then it wasn't. and your explanation is very plausable, i usually fill my tanks with the bucket method, but i decided to use my hose on this one because of how much volume of water i needed to put back in there. i guess i shouldn't be lazy when it comes to filling the tank

do you think if i i kinked the hose to allow the water out with major white water, would that realease the gas?
 
Yes, it would. More white=more aeration, as you know. :)

And there are rumors of gas bubbles killing fish by forming in their bodies. So I'm very paranoid about bubbles appearing after a w/c. Better safe than sorry, I say.
 
i know what you mean! i need to do another large water change so i will do it that way!im worried about that to, i just never did my water changes like this! i will do the white water refil, ha it actually fits.
 
Are you on well water? My well ocasionally gets lots of dissolved gasses, which come out of solution when the temperature of the water increases, kindof like boiling. The difference is is that it makes the water very cloudy. usually clears up by itself in a few minutes. This does not sound like what you are describing because you stated that it only developed on the side of the tank away from the sun. Usually gas bubbles get caught up in strings of algae which cause the phenomena your talking about. Also, they don't usually come out of solution as the water is leaving the filter, they usually disapear before they make it out of the filter.
