HI Chihiros 😊
I have a WRGBII Slim on a 60cmx55cmx55cm tank. I don't have Co2, not confident in this. So Low Tech. My plants are losing their leaves at the bottom (4 months in to this tank). I started low R=30 G=25 B=25. Slowly increased but seem to be buying new plants every month due to thinning and ended up with algae on the plants. Water is crystal clear.

With this tank, and low tech at 4 months, what are the best settings please. On the Facebook Page a few laughed at me, others said you cant use Chihiros without Co2, yet its not advertised or sold saying only Co2.

This photo looks ok, was a month or so ago, last night I pulled out 80% of stem plants due to no leaves.

Thank you for your guidance.
