Can any one tell me why this brown slime has come ? I've used mamouth p for the first time this week and the canna range ? It's a wilma tank ? Could it be out of date mamouth ?

Generally, organic products or products that contain microbes (not all) generate slime in the reservoir after 48 hours. If you prepare a solution for more than 3 or 4 days, it is recommended not to add organic products, or simply clean your reservoir well between each solution preparation
