Dear All Experts, I'm a beginner in this hobby. Apologizes me if asking 'stupid' question. i'm have been running my tank (fish + some LPS) around 1 and half months. The tank is running as normal before until i'm introduce the new led light to my tank. Some brownies algae start to grow on the glass and the sand bed. Not matter how i'm cleaning everyday, the algae come again the next day. I'm seek your helping to advice how to eliminate and stop the grow of these disgusting algae. i'm feeling the algae grow might due to the new light i'm installed recently (1 week before). i'm currently running my tank with chiller setting at 26oC and cut in at 28oC. The Lighting setting follow the default as following: 6.00 - 7.00: White light - 0% Blue Light- 20% Red Light - 0% Green Light - 0% 7.00 - 7.30: White light - 10% Blue Light- 100% Red Light - 100% Green Light - 50% 7.30 - 19.00: White light - 100% Blue Light- 100% Red Light - 100% Green Light - 100% 19.00 - 19.30: White light - 30% Blue Light- 40% Red Light - 100% Green Light - 0% 19.30 - 22.00: White light - 0% Blue Light- 100% Red Light - 0% Green Light - 50% The Brownies algae grow at the sand bed The brownies algae grow on the grass Some white worm on the LR Thank in advances.
