Thanks Tex, I appreciate the feedback/advice.
1. I gave a half dose of Flourish comprehensive until I get some Iron.
My current dosing regimen is still being adjusted, but right now it's
NPK 1/32tsp 2-3x a wk
Micros half-dose a wk
Excel recommended dose daily.
I feed ~3 crushed grains of Colorbits daily.
2. The thread algae (or spirogyra?) is slowly gaining on me.
I should have done a bleach dip on the plants from the LFS. I know exactly where the thread algae came from, but I didn't think it would cause a problem. :/ I guess I'll try adding an amano shrimp? (not the most aesthetic IMO)
I tried manually removing, but they just come back daily. I hope it isn't spirogyra as it seems like a PITA.
3. Maybe my water is pretty soft?
I was thinking about my high/unreadable GH, and did some digging. Seems like you often don't get a color change on my kit if you have very low hardness. I checked online for my water report and this is what I found:
If I'm reading it correct, I have pretty soft water.
4. After some research, it seems I may have a "true" honey gourami.
They often get mistaken for "dwarf honey/sunset gourami" which are actually larger
than the "true" honey gourami (1.5-2" max). It also has a slight black lateral line on it, so it may be a female.
