I have this algae all over the wood which I don't mind too much but then it just spreads onto nearby plants and epiphytes.

I use co2 and the light is a hygger on 80% for six hours. I did have some cynobacteria but used a product and now that seems to be gone but not sure how to tackle this

Recently this particular algae has been popping up, it seems to be firmer and harder to remove than the usual green hair algae, and they grow on the tips of leaves. My bucephalandra seem to be affected the most by it since they're always susceptible to algae. My neocaridinas, amanos and ramshorns won't touch it. How do I deal with it? Thank you :)

I introduced 2 lily plants to my pond 3 weeks ago more or less. They’ve been making new leaves but lately the last ones have been super tiny and darker. Is it normal? Should I do something different? I know the water could be clearer but I’ve been fighting for my life with the heat and direct sun! I will attach a picture of how they looked right after I planted them

I’ve been growing Rotala H’ra in various conditions, so I lined them all up to examine the differences.

Growing conditions:
• Greenhouse: Grown in high heat (70–100°F) with high humidity and good air movement.

• Indoor: Higher light intensity than the greenhouse, high humidity, cooler temperatures (66–68°F), and lower air movement.

• High-tech: Moderate–high light, 75°F, high water movement.

Conversion to no-tech (tub with soil sand cap and no filter or water movement):
• High-tech to no-tech: Converted faster than the indoor emersed plants. Showed slight melt/holes on the lower leaves and overall more melt than the indoor-grown emersed plants.

• Indoor emersed → no-tech: Slightly slower to adapt. Emersed leaves had less melt and looked healthier than those from the high-tech conversion.

I’m fairly happy with growth on all plants except ludwigia pantanal. Added a closeup in second photo - stunted growth + white coloration. Any overall deficiencies seen in tank? And specifically any idea what’s going on with ludwigia pantanal?

I’ll add some info:
6.4 ph co2 on
104 tds
2 kh
6.5 gh
Nitrates rise about 15 ppm per week (typical week starts at 10/15 ppm then reset with 50% WC with remineralized RO)
Add miracle grow daily that equals 13 ppm over week
Light stocking and light feeding
All visible growth is with miracle grow except altherneckii mini in front. I’d ignore those since recently planted

Could use some help identify these cuttings. I thought they were crypts but they're growing much longer than I expected. A Google lens search brings up hygrophilia. Any other guesses?

Location: Northeast Florida
Pink flowers. Google says it’s a type of lotus but I’m not sure and would like to know the exact species!
