White film in aquarium?
We’ve got a 29 gallon tank. It’s been running for about four weeks and we’ve had about four weeks. We had a bad run of some sort of parasite and lost all but our angel fish and shortly after the water went cloudy and within a matter of a couple of hours we had a white film all over the glass and plants (they are fake). We took the angel fish out and drained and cleaned everything in the tank and refilled it. It ran for about twenty hours and then the same thing happened. We didn’t clean or change the gravel so I’m thinking maybe that was the problem. The fish seems to be fine and all the levels are normal, ph is a little high but we are basically re-establishing the tank. I will try and attach a picture if I can figure out how.

its probably a fungus, not a parasite. try cleaning the tank again and dont turn the lights on, that way the fungus will not be able to grow and or wont be able to survive.
you will probably restart your nitrite cycle by doing this but regretably it may be the only easy way.

Sounds like either a bacterial coating or fungus issue.
What exactly are the water chemistry readings (“normal” is subjective) and the temperature reading?… and what kind ,how much filtration?
Parasites… what did you treat with?Were you using carbon,and did you remove it during any treatments?
One of those things where every little bit helps to come up with something.
That looks like a bacteria or fungus of some kind. What I would do is take everything including any substrate, filters( taking the entire filter apart), plants everything out. Although it normally isn’t recommended sometime it’s an emergency you can rinse everything including the tank in a very weak solution of Clorox. I would leave the gravel or sand soak for awhile stirring it occasionally.You will have to rinse them many times. When you put the tank back together remember to use a dechlorinater in the new water. You will basically be recycling your tank.
It’s a fungi. Wouldn’t actually like to guess why, but it needs nutrients, so the cause is something fungus edible you have put in the tank. Not a big deal to the fish, but if you want rid of it, take the carbon out of the filter and use methylene blue. That will kill it pretty much instantly and it will end up as a slime ball in the filter.
I actually think blue water looks cool, but it does stress the fish, so rinse the filter, replace the carbon and do a big water change the day after. Regular small ideally daily after that till the water clears.
It is most likely a bacterial bloom that is just part of your tank’s natural cycling process. If your tank has only been running a month, then this is pretty likely. I have seen this quite often, and almost always in new tanks, similar to the cyanobacteria outbreaks that can happen in new saltwater tanks.Bacteria double at an amazing rate, so it’s not surprising that this took over your tank within hours after cleaning it.
My suggestion is to do more water changes to get rid of it, but do NOT change the gravel! You will be completely starting from square one in establishing a healthy supply of beneficial bacteria in your tank, which grow on all the rocks an decor. Instead, gently scub them off in some dechlorinated water, just to get rid of the gunk buildup. Also be careful not to overfeed your fish.
This will probably eventually pass in time as your tank becomes established, as long as you keep up with your water changes.I suggest changing your filter’s carbon out also and maybe add a powerhead to provide lots of adequate water flow to keep this stuff from settling in your tank.
I realize that the gunk may look ugly for awhile until it clears, but I implore you not to give in and break down your tank! It’s a bad idea and you will probably regret it. Good luck
Looks like a fungus…
when you treated your fish it sounds like you killed the benefical bacteria in the filter in the process, alot of gram negative meds will do that.
that caused the bacteria bloom (cloudy water) and the subsuquent bad water quality allowed this fungus to thrive.
methylene blue
quick cure (malachite green) will work and won’t kill the filter.
even a salt bath may work..
good luck
This is not a fungus. It is a bacterial bloom. Fungus wouldnt have killed the fish unless it attacted the fish directly. Instead it is a bacteria thriving on the oxygen in the aquarium, this is why all you fish except the angels died. Cichlids can live in very low oxygen environment. The fact that this is a newly setup aquarium, also attributes this to bacteria.
