Hey aquarium experts,
Having hair algae in my tank and have been fighting them for some time. If I stop the lighting they tends to disappear after a few weeks but easy to come back once I resume the light. I have plants in the tank so I have to turn my light on.
Here are my setting:
Light: 4 Hrs per day at night. Super bright LED, some sun light through the window blind during the day
AQUANEAT LED Aquarium Light Full Spectrum for 36 Inch to 44 Inch Fish Tank Light Fresh Water Light Multi-Color
Total 84 LEDs, 60 pcs 6500K white LED, 12 pcs blue LED, 6 pcs pink LED, 6 pcs Green LED
Mode: all lights on and all lights off
Tank Size: 40 Gallon
Temp: around 71F recently
Fertilizer: Easy green twice per week, API CO2 booster once per day, easy green root tabs
Filter: MarineLand Penguin 200 Power Filter, 200GPH
Substrate: Fluval Plant and Shrimp Stratum, gravel and white sand
Algae eater: 7 Otocinclus catfish & 7 mystery snails
Any idea how I could get rid of the annoying algae based on my settings?
1. Is it because I don't have enough plants to compete?
2. Should I put on a black tank background paper to block the sun light go through the window blinds?
3. Does water flow have impact on algae grow? Shall I increase or decrease water flow?
4. Do I have enough algae eaters? Do I have to get some shrimps?
Thank you for your help!
