Why my plant seem to get destroyed? I have around eleven or thirteen small fish, nclude pleco My normal tempreture at first was 26~27 inside aquarium, but very fast, i made a fan cooling system, took it to 21 at mid night, and 23 at days. i do not have any deoxyd carbon system, but a normal dual out let pomp of air that intake normal air and pomp it to aquarium. i still didn't bought any (i don't know the word, but the things they give to plant), can afford it till next week, and i don't have any aquarium led red/blue'ish light. the aquarium it self isn't under direct sunlight at any time of day, but still near window.
