Hi all,
A really dull topic for my first post, I know, but I've been here in the background for a few months, watching and reading.
All has been going well in my high tech planted 54l (60cm) tank until about two days ago when a white biofilm started to develop. It has worsened overnight into an almost complete sheet across the surface of the water. I can drag my finger through it and lift skin-like sheets out....
What causes this and what can be done? I have very little surface agitation, but the tank has been set up for months without issue and I haven't [knowingly] changed anything. I do 50% water changes once per week, as per EI, and I have an Eheim 2213 on it - giving me a turnover of roughly 9x per hour..
Any ideas gratefully received. Please consider this a white flag!
Many thanks,
Ben
