Biofilm in axolotl tank wont go away

[axolotle42]

Hi I have had a bio film problem in my tank for about 2 month and I cant get it to go away. I've been doing for frequent water changes but not only is this tiring but I dont want it to interfere with my cycle. any advice? it attaches to my plants and also sits on top of the water.

I would guess that it probably is related to the water quality of your tap water. Do you know how the water in your area is treated? Obviously, you don't want there to be chlorine or other bacteria-killing chemicals still in the water when you add it to the aquarium, but it does help to clean up the water beforehand. I would suggest trying out spring water for a little bit, and if that seems to clear up the issue, maybe invest in some kind of water purifier?
