the problem i have is, the new tank is a second hand one, and it was a bit grubby. i've scrubbed it all over, but there seems to be a slight film of dirt over the glass. its quite hard to see, and wont seem to shift with filter wool.
does anyone know of any sort of cleaning stuff i can use to loosen any dirt so it scrubs off better? i am worried that any remaining dirt may harm my loaches, but then detergents could leave traces behind that could harm them too.
my striata, yoyos and the birdii? that Emma has for me will be going in the tank eventually
sorry to ask such a silly question!
