I've had success with Purigen before on Ian holdichs recomendation, seemed most effective run with carbon so thought I'd give carbon on its own a shot see if it makes a difference.Hmm, call me stupid but that is something I hadn't put together.... Now I think about it I've used loads of carbon in the big tank both times on start up and no diatoms.
Is this a well know trick that I've missed along the way tim?
Black & green yes, trying to stop the brown & green, it's not such a good lookOh and still love the 40, black and green works so well.
thank you Roy.Hi Tim, Superb Little scapes
