How do you make a rock waterfall?

[superdartfrog]

Hi

i am just in the process of doing one my self, small 600 litre hr aquatic filter, £10 from ebay, £3 on plastic pipe, a small peice of glass, free, aquaruim sealant £10 x

Here is the photos of the mk1 version, however, its seems a bit to heavy so will be using a 30mm x 6mm x 300mm next later this week.

All you do is aquaruim seal the peice of glass, then add stones to build up, aqarium seal every stone in place, when complete, aqarium seal it to your tank, make sure its secure, on a slight angle adjust water flow, waterfall.
