After a month of my hard work on maintain the tank, now it's looking better and with healthy plants, the Red Cherry cleaned up a lot of algae on the stone and leaves. Biweekly change water also helping a lot on reduce the algae from propagates, trimmed a lot infected leaves and minor rescape done in the past month.
Later will consider add in some fishes, but afraid of the young shrimps can't survive long. So far, I am happy with only shrimps & planted tank. Need to keep the shrimps healthy, I think with the algae inside is insufficient for them, will buy some shrimp's food to feed them soon.
