Hi all.
A friend of mine has a 120cm/48" tank, mainly with Cyperus Helferi, Echinodorus Parviflorus and Anacharis.
Most/all of the a covered by a black coarting, it looks like some kind of black algae, although we are not sure if it is algae or anything else?! The black coating starts in patches and covers the entire leaf after a while.
The plants are growing slower, once they are "infected". Additionally some green thread/hair algae appeared on several spots. Stones are also affected..
The black coating appeared after approx 2 month of initial setup. The Tropica soil was used for the tank.
Light is on 2pm - 9pm, CO2 comes one 2h before lights until 8.30pm (2 bps). The amount of CO2 was not increased, since some of the fish (Guppies) start gasping on the surface.
The water is being aerated from 9pm to 11am.
Water conditions appear normal, ph is at 6 (which is the measurable minimum).
Ammonia is 0, Nitrite is 0 and Nitrate is at 100ppm.
GLA ferts ( https://greenleafaquariums.com/products/pps-pro-aquarium-fertilizer-package-bags.html ) and the PPS system are being used on a daily basis.
Anyhow, it seems something is unbalanced, but the question is what exactly is not in balance and how to correct is or what the real issue is ...
Thanks a lot in advance for your help!!
