My tank is ~1year old and recent few months I've been struggling to fight the fuzz algae. Weekly 70-80% water changes, added canister filter - nothing is helping.
Monte-carlo grows well and generally looks good. Baby tears grow for some time, then get white and then brown and die.
Alternanthera reineckii grows really well, but get all covered with algae, which I guess is a sign it's not feeling great.
Currently, I change 1 gallon a week.
tank - 5gallon
light - MICMOL planted running at 70% for 8 hours a day + 2 hours ramp up and ramp down.
substrate - 1 yo Amazonia.
Here are the parameters:
temp - 76-77
ammonia - undetectable,
nitrites - undetectable,
nitrates - also undetectable which is weird
ph @11am - <6 (it's off the API scale, orange-ish, I guess it's 5 or so), another sign of its acidity is that the snail shells get dissolved over time.
KH - 2-3
GH - 2-3
I dose flourish 1ml a week and LeafZone 2ml a week.
Is there a way to fix it? Thanks.
