Thanks for sharing! I’ll definitely try these. I love the fact that they also show fungal contamination.
Any expreiences on tolerated levels? I believe that rotting leaves, elder cones or any other matter will promote bacterial and fungal growth, which then can only be limited by very low pH and water changes. Am I right?
Also, I’ve read, that the fry of other blackwater fish feed on the mold (fungi?) that developed on decaying plant material. Is it wise to keep a tank close to sterile?
Best, Thomas
