I am having an algae outbreak I am not familiar with. I will provide quick background on tank.
7.9 gal nano Ebi up for about 3 months.
26 watt CF light - Finnex lamp.
Eheim 2232 with lily pipes (installed 1 month ago) at 75% flow
EI dosing with dry ferts and Flourish
Weekly 50% water changes
HC carpet only plant
Fish are 6 Otos, 15 chili rasboras, 10-15 RCS/CRS
I recently lost some shrimp due to what I suspect were high nitrates in the 100s due to a person overdosing my tank with KN03 while on extended OT at work. The algae may have started before then I believe.
The only recent changes are lily pipes about 1 month ago and I have been trying to do more water changes and dose less KN03 to lower nitrates.
I have some diatoms and light green algae on the rocks which I am familiar with and expect at this point in my tank.
The algae in question is brown/green and stringy - seems to be intertwined in my HC and hard to see or photograph.
Current tank params:
Nitrates - 40 ppm
Nitrite - 0 ppm
Chlorine - 0 ppm
pH - 6.6
Temp - 78 F
GH - 4.4
KH - 7
Drop Checker - Lime green just bordering yellowish

Thanks so much
