Any idea what is causing film on top, 5 weeks in with a fish in cycle - reading are a little up and down. Completed a 25% water change, as well as 1st cannister filter clean/rinse ( aquarium water used) today. Trying to build up volume of plants in tank, however, there is a resident L191 who is less than tolerant, hence the transition to floating plants 🪴
