Hi Skozzy

If it is 1M deep you'll be looking a 9000 Litres of water, will you be
mixing this or bringing in from the sea? How many tons of live rock will you
be using?

I recall that evaporation from my fathers swimming pool (about 27 000
litres) was significant over summer months when I was younger, will you be
using RO water for top-ups? Your water changes will be not unlike a swimming
pool backwash!!

I've not done this but have read of people doing the same thing. I hope
you'll be posting pictures? I imaging that Scuba or Snorkel equipment may
become the norm for your routing maintenance?

Good luck!!

Chris

A while ago I wanted to setup a pond outside, but after playing with reef
setups and salt water I am thinking of the idea of making an outside salt
water tank, but not the usualy glass type, I was thinking of making a
wooden
frame about 3 meters x 3 meters and about 1 meter high then sealing it
with
fiberglass, then adding in the usual pumps and filtration and putting in
some live rock and some fish. It's be able to save heaps on lighting the
setup and put that money into maintaining the temprature with a decent
chiller.

I would like to hear some feedback from people about this idea and some
possible problems I might be looking at. Or some possible good things ?

I was thinking that it might help in growing some alge on some new rocks
fast then in a normal tank too. ??
