om...
I'm planning on building a pond next spring about 4ft * 4ft and 2-3ft
deep. I wont be having any fish just a fountain in the middle. I'll
have 2 rows of paving slaps round the pond as it will be part of a
patio/terrace.

My questions are

1) will I need a filter if I dont have fish

No. However it will likely get algae unless you have UV system, or use
algicide from time to time. Are you planning to have plants in it (can be
affected by algicide whatever the makers claim, IME)
Is there any particular reason why it will be so deep? Seems unnecessary if
you just want a fountain to look at.


2) How do I get the pump\lights cable into the pond. Is it usual to
run it under the paving in which case what about maintence. I plan on
having a junction box at the edge of the paving 'hidden' by plants.

I prefer low voltage devices (uses a transformer inside the house) rather
than 240v. In either case, put the cable inside hose pipe buried at least 9
inches deep (instructions will say how deep) if its 240V or for low voltage,
a few inches is fine. I think you can get armoured hose pipe or special
pipes for 240v cable, but you will need to check, anyway for your needs low
voltage will be fine, why increase the risk of electrocution for the sake of
£20 extra for low voltage?
