The situation is as follows: there is a 20l gross mini-aquarium, the photo of which I have already posted in my thread. The aquarium is populated with zoanthids, LPS, 1 acropora, and discosomas. The mobile fauna includes 1 dragon mandarin and 2 shrimps, a few blue-legged hermits, trochus, and strombus. Filtration is through Seachem chemistry in a hanging filter. Feeding is minimal. Initially, there were remnants of higher green algae, similar to fluffy Christmas trees, on the live rock, which I liked and did not disturb. But now these algae have grown into a rather dense carpet on the live rock, suppressing the zoanthids and discosomas. Now the question is: what can be added to this 20l aquarium as a permanent resident to weed out the algae and not suffer
