" Filtering a sal****er tank has changed so much sence I had a sal****er
set-up - mine was fish only and filtered with an UGF, as were the salt
tanks in the store.

Me too. I have had a couple of marine tanks in the past. I have managed to
find some details on a couple of them if you fancy a look. They are at my
page under the marine link, www.marksfish.me.uk, as well as my current
project.

Last year a friend asked me to build him a sump for
his salt tank. After a ton of homework I used the sump found here;
http://www.reef-eden.com/DSBs.htm , with a few small changes to make it
a little easyer to build. I used a 20 gal.all glass tank with a 10 gal.
all glass tank within it for the DSB.

I had a look at a sump from here http://www.melevsreef.com/sump.html. Mine
is basically a three foot tank with glass dividers in. In the first chamber
which has a flow under plate, I will put some egg crate at the bottom and
some bio balls in the chamber. The second chamber I will place a heater.
Third chamber I will put my Caribsea Aragonite fine sand to an initial depth
of 2" (I did consider Miracle Mud but the UK cost is a bit prohibitive) and
caulerpa culture. 4th chamber which was unnecessarily caused will be empty
and chamber 5 will have the return pump in it. Looks like I will be leaving
out the cell pore this time!!

Hopefully the structure goes into place in the next couple of weeks (fingers
crossed).

Thanks for all your input Frank.
