Please help green water??
So for a while now my tank has been this gross green colour and i have no clue what it is or how to get rid of it, so any suggestions would be greatly appreciated.
p.s the glass is also going cloudy
i have tried doing 50% water changes every other week, as well as 25% changes every week and also cleaning the filter every week (because it gets reallllllly dirty)
Size: 40L (10.6 Gallons)
pH: approximately 7
Other parameters unknown as i cannot afford a test kit
Filter is an Aqua One Nanoflow
Tank Friends: 2 mystery snails, bunch of red cherry shrimp, 2 x glass bloodfin tetra, 4 x neon tetras
2 air pumps are going because i also had troubles with oxygen but this has helped.
Thank you so much, I've had this tank for about 4 years and this has never happened before.
