I've had my planted tank set up for about 8 months. The plants I bought were supposed to be hardy and easy for beginners but most of them have gradually died off. Things have been better since I added CO2 but still not great. I have observed plenty of new plant growth in the plants that I still have but the leaves develop holes, turn yellow or brown, and start to decay and fall off. I am also having an algae problem. Here is some info about my tank and a couple of pics:
Lighting: 36" TrueLumen Pro LED 8000K
Water: Tap water with tap water conditioner added
Water changes: 25% every two weeks
Fertilizers: Flourish Trace and Aqueon Aquarium Plant Food (not measuring, just pouring in a little bit a couple of days/week.
Fish: 5-danios, 5 red-eye tetras, 1-gold nugget pleco, 3-burmese border loaches, 1- boesemani rainbow
I have more pics but for some reason I can only attach two.
If you know what I'm doing wrong, please respond.
