The light was a huge issue now that I think about it. But I am also thinking I may have caused this also by over feeding maybe. Possibly some flakes got stuck along the floating plants and just sat on the surface which acted as a major fuel for that stringy stuff. When I was gone I had a fish feeder that I used before. It was set on 12 hours on a low dosage setting. However it could had been putting out more than I thought. The bio load from fish is not that big I dont think. Right now I have one betta and 6 neon tetras in my 50 gallon.
If I take the air stone out it will create no surface movement. Is it ok with no surface movement. I am afraid that the stillness helps create a living environment for that stringy stuff and protein scum. Based off your aquarium pictures I could not see much movement on your surface.
I have adjusted my light timer to 12:00pm to 10:00pm.....will 10 hours still be too long?
The green string is algae, I suspect Thread Algae. Apparently excess iron can cause it, and it often appears with Hair Algae.
If you go away for up to a week, don't feed the fish. Those auto feeders frequently fail, and other members in previous threads mention much the same results, some much worse. The protein scum and that brown stuff are definitely organics-related, and an excess of fish food could well cause this. Algae occurs due to light. But all this is obviously inter-related/connected.
I have very little surface disturbance because it does drive off CO2. A surface skimmer attachment to a canister filter will deal with the scum, i used to use these with my Eheim canisters but then fish kept getting pulled in and rather than try to make screens (which floating plant leaf bits will clog
) I just took them off. But I never had protein scum with the skimmers. Now I have it minimally in a couple tanks, seasonal it seems. Some tanks never. All organics-related, and each aquarium is biologically different. Protein scum is no harm unless it gets very thick, then it will "suffocate" the tank by preventing the normal gaseous exchange. At its worst for me I simply siphoned it off weekly during the water change. That tank was torn down as it was not balanced.
Until this is cleaned up, you might want to further reduce the light. Down to 8 hours perhaps. Once the tank is biologically stable again, you could increase the light, keeping an eye out for any algae increases. It is odd that I used to have my tank lights on for 15 hours daily, and no problems. Now I have them down to 8 hours to keep brush algae at bay.
