I have a 56 gallon tank with an Oscar and a Severum. The tank has been in place for about 2 years. It has a wet dry filter, gravel and one resin pot. There are no plants in the tank...no artificially colored rocks...and the pot is about 2 years old. As of late, every time I change water, the water is pink by the next morning. What causes this????
Hello and welcome to the forum!
I have never heard of this problem. How does the water test for ammonia and nitrites? What kind of pot is in the tank? Any driftwood? Tap water look clear? You say the water is pink after water change days, does it clear up or stay pink? Can you post a picture of the tank?
That was a lot of questions. ;-)
This is really odd and am at a loss to even suggest anything for you to remedy the situation.........Have you recently switched foods you feed your fish?...........Have you used any meds in the tank recently?...........Only thing i could offer to try, is running some carbon in your filter for a few days and see if that helps.......
Don't have any more questions to add for you apart from the above, but welcome to the forum!!!
For inserting carbon in the filter, I'd be careful cause this will also harm your needed, beneficial bacteria.
in a tank thats 2 years old you will not need to worry about it harming your beneficial bacteria that much
Just a quick guess but it has to be either 1) dye or other coloration leaking from something or 2) some sort of microbial life form that either produces a pink substance or is itself pinkish colored when seen in large numbers. Just a guess.
I remember the "red tide" scare quite a few years ago where some sort of microbial creature was clogging up the shellfish beds, i think it was on the east coast of US. It was poisonous too...
here on the east coast, specifically florida, we have a red tide every year.....it is VERY toxic to the marine life as well as humans
The pot is resin, or plastic, and has been in this tank for two years. There is no chance the color is coming from the pot.
There is no driftwood or colored gravel in the tank. The gravel in the tank is also two years old, and is natural with no artificial colors.
The water is tinted pink, but not cloudy. There are no plants, real or artificial, in the tank. There are no signs of any algae growth.
This change gradually occurs when we change water. We can see it roughly 12 hours later. It looks like someone took red food coloring and placed a few drops in the tank...just enough to tint the water.
We have had no recent change in food, fish, or anything in the tank.
The only thing I can see that helps is salt. If I add salt, the tint will disappear in a few days. The color will then reappear at the next water change.
Water parameters - pH, hardness, ammonia, nitrates, nitrites are all normal. We do not run carbon in our wet dry.
The fish do not seem to be affected, I am just curious as to what this is.
I will try to take a pic tomorrow in natual sunlight :o)
mommybritches.....that is very strange...do you use tap water? if so, maybe you could look into the resent testing the city/county has done on it and compare to previous ones and see if something is different from that aspect....just a though....
Wow this is some odd stuff....then the only thing it can be from what you're saying is your water source....Do you have some type of larger glass/ clear container you can put 1-2 gallon water in and let that sit over night (like you said takes about 12hrs to appear) and let that very water "settle" so to say and check if it also turns pink over night?
That's the only thing I can think of....
