480g no more...

We went to Namibia during the last week of April, and something terrible happened. I have filled the 480g to the max with RO/DI prepared saltwater, in order to have the live rock complete the curing process while we were away.

Update on the 480g

Last week Tuesday Exotic Aquariums delivered the newly rebuilt tank to my house. It has 3 bases like I said, each 10mm thick. The side panels are all 12mm thick. The square tubing frame is much stronger too.

After the usual struggle it has been moved in to its old spot - over the sumps which I have joined together in the mean time.

I am sooooooo excited!

Yesterday evening I could not wait longer. At midnight I needed about 40l of water to close the loop. That takes about 2 hours to make, so I decided to go to bed instead.

This morning I filled the remaining water and voila - everything worked. No leaks (touch wood). However my durso standpipe was not working. Water was oscillating up and down vigorously. I decided to remove the top and cut off a 4cm piece to lower it (it was too high). Since I dread leaks I cut it in place - and did not remove the pipe from the overflow.

Followup...

Actually I was slightly wrong with my observations. The pipe leading from the overflow to the skimmer was actually inclined away from the skimmer - a couple of degrees...

I removed 32mm of wood from the skimmer's base support and replaced it with 25mm polystyrene. It seems as if I have a slight downward slant now. Will start the circulation back up in an hour's time.
