Hi guys im struggling with detritus on the sand bed and algae growing on the rockscape. LFS suggested a goby but im reluctant to buy one as ive had 2 and lost 2 already one due to jumping, and one just died a few weeks after purchase. LFS also said the detritus would pass after a few weeks but ive been suffering with this for a month or so now and the recent boom in algae growth has my conserned. Any help would be muchly appreciated.
