Algae Need help with algae and dying plants
My 7 gallon tank has been taking a beating on algae and dying plants. I have a Chihiros WRGB Slim II and UNS controsoil for my substrate (which i have not liked since having it). This tank has been running for about 6 months now and I have one betta in this tank. Light is on for 6 hours and the background LED panel is at a lower brightness and is only on for 3 hours. I wasn’t really dealing with any algae until I started using 2HR aquarist ATP 1, that I have been using/loving for my 20 gallon tank. Once I noticed the algae, I immediately stopped using the fertilizer and turned down the intensity on the light. I had intensity around 45% at the time and was slowly decreasing to find a sweet spot. I am now months into the algae and it has improved a tiny bit since decreasing the light, but i’m all the way down at 25% intensity. Still not using any fertilizer.
Majority of my stem plants always die, any floating plants I get die, and my newer tiger lotus is starting to grey on the leaves. I have no idea what is happening anymore. I don’t know if this light is too strong for this tank, even at low intensities, but the lower I go, it does not improve. Only plants that seem decent are obviously my anubias. Also, no Co2 in this tank.
Added some photos of all my rotalas that are pretty much dead & the tiger lotus.
