I have crystal clear silica (white) sand and i only used a full back of 4.5kg to fill up my 4ft tank.
I have a plec and i was aware that there will be a lot of his excreation around the tank but is there any way of getting rid of it, like a certain filter best for them. I think i might be giving him in to the lfs shop tomorrow anyways.
This type of sand is really fine and snowy type, when my fish move around a lot of it floats with the current and settles back down and its really funny as with my common plec has got a armor type skin, my congo cichlid spat some sand out of his mouth onto the plec and he looked like a snow plec lol.
