This tank is my shame.

My 10 gallon tank is just under a year old now, and I’ve had a huge algae problem nearly the entire time. I’ve tried everything I can think of. I have cut lighting down to 5 hours a day in the afternoon, I’ve cut the amount that I feed quite a bit. Only 4-5 flakes a day, and occasionally 1-3 bottom feeder pellets. Params are in 3rd photo. Usually, evaporation takes a good amount of water out of the tank weekly, so I’m just adding probably around a gallon or two of water a week, but I vacuum the substrate and manually remove as much algae as possible with a tooth brush once a month. Plants in the tank also never seem to be doing awesome, but any plant that I grow hydroponically in the tank takes off. I read that this type of algae can be caused by low CO2 and was recommended to overdose flourish excel, hasn’t done anything so far. also read this type of algae can be caused by low nutrients, so I started dosing the fert that is seen in the 4th photo, hasn’t done anything so far. Stocking is: 2x adult platys 5-6x young platys 2x shrimp (unsure which species) 1x kuhli loach
