Sorry for another surface scum thread. Most of the posts I read about this seem to indicate this being more of a high tech tank problem. I did see this a bit when I ran a high tech tank but not much, since setting up a low tech tank this is rife.
Tank details:
Aquanano 80 (130L) - with stock LED light, pump and filtration through the back sump.
Substrate - Aquagrowth Aquarium Soil
Plants - java fern mini, Bucephalandra, Cryptocoryne beckettii, Rotala, Helanthium Tenellum, Heteranthera Zosterifolia, MC and Xmas Moss.
Light Period - 6 hours
Dosing - EL ferts at ~ 1/10th
Also running Chihiros Doctor.
Tank has been running for 6 weeks.
The plants seem very healthy. The stems have been trimmed twice in six weeks which makes me think maybe the stock light is brighter than I thought it would be.
I added another internal filter to increase the surface movement, I didn't want to do this as the appeal of the tank was that everything was hidden. It helps, but not much, as you can imaging the surface of the water in the sump area is totally white due to no surface movement. Water changes help but within 3 days its back as before.
Does anybody have any experience of this with low tech tanks? I guess I'm going to have to try a skimmer?
