I have this 55 gallon tank for almost over 3 years now and noticed a build up of these very fine white stuff on top of my water. My tank consist of 5 discus and 3 clown loaches and one wood log, nothing else. If I recall correctly, it might have happened after I change water conditioner, using AquaSafe now, was using StressCoat with no issue. Just wanted to know if anyone has gone through a similar situation. These things are so fine i cannot even remove it with my regular fish net.
Looks like fungus. But it also can be dust particle, if it is a open hood one. What is the water condition? Chk it. How about the fish? Are they look/Behave OK or not? What about water change?
What kind of gravel and filter you are using?
I only can suggest to do partial water change of 20% each day of 1 week.(This is an advice of Achintya, (the master of discus
Hope that helps.
You could try a brine shrimp net, but that might take a while on a 55.
I got similar "flakes" in my tanks because of the hard water before I moved. Mine was calcium and I just skimmed the top of the water with a paper towel.
Might also be a build up of protien....this is usually a film but if let go too long will develope in spots like this. If it is also in an all over "film" does it have a rainbow sheen to it?
The idea of a paper towel absorption works for protein too. I also remove reveral buckets of water by sinking a bucket into my tank then tilting it so the water just trickles down the inside....this skims the surface and I find it to be more thorough.
Thank you everyone for responding. I will try the different methods mentioned so far to remove it. I do not think it is harming my fish as they all look very healthy and are actively feeding. I would guess that my water hardness is pretty high and hence the calcium or protein build up? I need to do a water check once I have more time. I did forget to mention that it is a new environment for them as I have recently moved into this house.
Attaching another photo of my filter system. I am actually using a converted Salt Water tank with built in filtering system, bio balls, sponges and water pump system. Noticed the white stuff coming together already?
Another question to the community, how often do people actually change the filter sponge on top? I will never likely replace the bio-balls as they have all the good bacteria in there but what about that top layer of of layered filters? Is it advisable to replace them every so often?
Hmmm... I might have found the answer to my own problem? LoL The way the water flows down the sponge does not make sense as only part of it gets wet. I have re-arranged it so that water flows over and drip down into the sponges. I think this should solve my problem. I will have to monitor and see. Attaching new sponge setup.
For the filter question: I never change any part of my filter unless it's falling apart or I need to use meds. I just pull out my media and sponge every 2 weeks and rinse it in old tank water to get some of the gunk off.
I have had that problem too. It happened in my 1 gallon betta tank at I've had for a few yrs. He was perfectly fine but this whiteish film covered the top one day and I thought t was dust so I left t. After a while it cover the whole top. I still left it cuz the water wasn't dirty but then my betta had fungus growing out of one of his gills but if you clean the tank whenever you see this it will soon enough go away. My betta lived. I cleaned his tank real well and put him back in a the fungus slowly disappeared. Everytime I see it forming I just clean his tank and problem solved
Never had problem like this...,BUT since I've Tanganyika set up with coral sand (water=pH 7.8 dGH~11 dKH~11)it happens.
First 3-6weeks it was like a film but then film dissaper and water surface looks like in Your Discus tank pic. .
So,seems to me its a hard water.
After water change that white point problem return into a 4-6days,must just change water.
If water arent change-surface becomes all with thousands white points.Is it Ca or what,i didnt know-just change water.

Hi I just very sadly lost five beautiful discus and one beautiful corey angel to a white fungus which is what sounds to me that you may have started. It will grow like wildfire. get a sample of your water to the nearest aquarium asap. This can kill your fish. If its what i think it is and what I had it is a fungus but makes the fish very suseptible to secondary infections. Dont ignore this. It could be fatal to your entire tank. Get a 10 gallon hospital tank set up just in case you need to get fish out if anyothers start to die. Observe your fish closely. good luck
I have fought this problem for quite a while too. Each time the film built up along the water's edge as the level went down from evaporation. I never had anything but crystal clear water so it was helpful to see the discussion of hard water / dust. The pictures were very helpful to see the problem was exactly like mine. Thanks, a few years later, to the group for help.
