Ok so this is my first real attempt at bubble buckets. Im running six of them right now and last night i noticed a small amount of algae growth in the buckets. Not alot but a little along the airline tubing. Also some of the airline tubing is turning green inside. I did some research and i see that algae first off requires light, and secondly is usually found in higher temp buckets. I havent measured the temps in my buckets yet(getting thermometers today) but im not really sure whats up. Is the airline tubing let in light? Should i switch it over to green/black? Im changing the reservoirs today and im also gonna look over them and double check to make sure there arent any holes in where the tape is. I posted some pics to see whats up. Any feedback is appreciated. Ive done alot of research and cant find much suprisingly so anything that can help would be great. Im loving these buckets but ive heard if you cant control algae growth then youre totally screwed. P.S. Only other thing i can think of is that maybe i waited too long between rez changes. The water in the buckets is ten days old and i didnt really notice algae til about 3 days ago(first signs were the green airline). Im changing it today though and cleaning out the buckets.
