Hi guys,
I've noticed some black or brown algae has been building up on older leaves of my Anubias and some similar stuff is slowly creeping up Riccardia carpets, so I'd like to ask for help identifying and fixing that mess.
Tank description is as follows:
- 20L Aquael nano cube tank, appprox. 3 months old;
- Light is medium (visually), Chihiros A25 at 70%, many floating plants (Salvinia), photoperiod 5-4-5 (4 hr siesta in the middle of the day);
- Filtration: internal Dennerle filter corner filter;
- Pressurised CO2, drop-checker is stable light-green; pH drop around 1-1.2 (from 7.8 to 6.6), with water kH 3-4. I don't switch off CO2 at night.
- Ferts: Tropica AquaSoil substrate + EI dosing;
- Plants: mostly slow-growing (Buces, Crypts, Anubias); Riccardia moss; quite a lot of floating plants (hornwort, Salvinia, a bit of duckweed).
- Livestock: around 15 cherry shrimps, some snails and 1 sparkling gourami.
The tank had been neglected for about a month until 3 weeks ago, as I was on vacation and no-one was handling it, but last 3 weeks I've been following dosing/water changes quite rigorously. However, it didn't make things better; the positive change I noticed is that plants started to grow faster; I assume it's because of better dosing and increased light.
Any advice will be greatly appreciated.
