Hi Barry,

I was going to suggest any of the pondliners Eg, Firestone EPDM Rubber Pond Liner (1.02mm & 1.14mm thick). When I did mine I ended going with the DuPont Xavan liners - 25yr guarantee. The ponds been in the ground for a few years and no leaks.

But as you may want to see the bottom of the pond, this may not be an option.

I sourced it from Creative Pumps in SA, likewise with the filter/pump/hosing etc. Rock Around the Block isn't too bad either. For the pump/filter I went with a brand called Laguna (Italian).

My entire objective when building the pond was it had to be low maintenance with maybe a filter clean every 4months.

One avantage of having it black is that the algae is not as offensive to look at over time to that of natural stones/rocks, it also creatives a nice dark contrast against vegetation etc. I guess to looks more natural.

A good pump/filter will keep your water to near perfect crystal clear, but over time, algae still forms on rocks etc.

Cheers,

Norm
