Yellow tank water

Question
I've looked over several responses concerning yellow water in the fish tank.  I too have this problem and have for years.  I have a 29 gallon tank, with primarily fancy guppies, one placostamus, one sharkfish, and one albino catfish.  Even when I have done a complete water change, cleaned all the stones, shells and plastic grasses and changed the filter OR carbon at that time, within a day or two, the water will begin to turn yellow like urine.  I know that I should do a partial water change every so often, but that doesn't really seem to help alleviate this problem.  This was the problem even when I had only 5 fish in the tank.  We do have well water and it runs through a water softener.  Otherwise, our water is not terribly hard, and I have used water from the tap that is not softened with the same results. I've never had the water tested for nitrates/nitrites, ammonia, etc.

Answer
Hi there,
I don't use well water myself but I have heard of people who have had the same problem as you. When the water turns yellow it may be due to levels of tannins in your well water or rust. You may have to investigate further into this matter. Perhaps get your water tested? Its certainly not pleasant to have that in your aquarium! There are types of filters available to filter out your tap of tannins and rust. I don't think it would be the water softener. I have used one before in the past without any issue like that.

Definitely a strange matter at hand... let me know if you find out anything!!

Best of luck!
