I started my SH bubbleponics grow about 20 days and I am noticing alge growth. The room temp. was about 85. I cleaned every thing out this past weekend and I have noticed its starting to come back a little. I also adjusted the room temp to around 70-75 after cleaning it out. There are no openings for light to get in other than through the bubbler tubes. Can I use some type of alge cleaner from an aquarium store to help kill it? If not what can I do or buy to help prevent it?
