Hi there

I have white pebbles in my tank and they are getting the brownish colour algae on them and it does not look good. Someone suggested changing them for Poolfiltersand. They said it is easier to mantain. For cleaning I now gravel vac once a week and they said I still do that, but I hold the vac about and inch away from the sand. Do you suggest sand as well, or should I just bin the white pebbles and go for a darker colour?

Curby how do you keep your pebbles clean and white? I would prefer to stick to pebbles, cause my bristlenoses loves to just lie and suck on the stones and where is the fun in sucking on sand I gravel vac 30% of my water once a week and it only recently started happening. Actually thinking about it, it started happening since we had very warm humid days

i have gravel in my breeding tanks but i have Sand in my grow out tanks for my Fry it is easy to clean i use a Turkey baster and suck up the left over food and poo with it

your white pebals are going brown and sounds like brown algae to me cut down on your lighting hours and for the next few days cover your tank over and leave lights off will help get rid of most of it
