Very very nice set up man. I am jealous π I also check other NFT diaries. And he also uses water pump not continuously. This way looks good t to reduce noise from pump. Only 15 min is nice for bed room or living room. How is the light schedule? I mean do you use ordinary 18 on / 6 off, or 6 on / 2 off three times in 24 hours? I guessed pump on is related to light schedule.
