Nice! I guess welcome to this habbyt, a mix of hobby and habit. Lol!
My advice, the more plants and filtration you can have with the least light is the key for low maintenance lush good looking clear water tanks.
Pressurized co2 makes it much easier against algae and plant health.
I see you're a word smithereener! Thanks for leaving your footprint here.
More plants on the way sir, and they are the low light variety: mini pellia. Putting them in the tank this weekend. Hope the addition of mini pellia will contribute towards lower maintenance.
Been contemplating CO2. Pro is as you've mentioned. Con is don't want the plant growth to be so high that the shrimps cannot support it with the amount of CO2 they naturally produce.
