Thankyou Mr Pond.
Erm, im wondering now, how everyone gets their concrete to slope towards the bottom drain? if you put the concrete in pretty wet, how do you manage to slope it without standing in the concrete itself????

I have been trying to find stuff about Bottom Drains all afternoon. Ive had a few quotes from brickies today and also a fibreglass man and im thinking the pond could be getting build VERY soon.
SOOOO....how do you install a bottom drain in a fibreglass (someones doing it for me) pond? I am going to be doing a concrete bottom, but what do i need to do? from start to finish, on the bottom? and does anyone have pictures pleeeeeease please pretty please.
Thanku lovely people. I want to get this right first time.

thasnks for that. i'll be certain to factor that in.

Thanks for that. I am now looking at doing an 18inch wall around the top of the pond. So it may now be 3 foot in ground and 18" above. I'm thinking, so far, that i may go for a 12x9x4.5 foot pond. Enough to start with me thinks. lol
Im getting a few quotes from brickies to do the wall. I hope its not too much money.

Hello all, I'm new to ponds, well ish. And im after some lovely advice from you lovely people.
I'm just starting to look into ponds because we're re-doing the whole garden i am a marine nerd and that is my confession to you. pmsl.
Anyhoo. I want a deep (for me) pond. I havent decided how deep yet. But i have been reading alot on here and am getting concerned for the sides of my 'to be' pond.
How deep can i go into the ground before i start? I want a sloped side and i dont really want to have to get supports everywhere for the sides. My ground is rock solid and to be honest, i think we'll have a job getting to 120cm down.
So, how deep can i go before i need to support the sides?
