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.

The 85kg of coral sand I had was not nearly enough for a DSB, and I'd go broke if I were to buy enough. The standard price is about R40 per kg... So I purchased 150kg fine crushed coral sand and another 120kg coarser crushed coral. It took about 6 hours to wash all that sand, but eventually it was clean and ready to go in to the new tank.

Currently it is filled 3/4 of the way with RO/DI water - still making more. It takes time - about 360l per 24 hours. But I think it will be worth it rather than to be impatient and use lesser quality water. The plumbing is all done - I just hope there are no leaks...

It is clear that the Nitrates as just taking over - killing all my inverts and causing stress on my fish.

I will post some equipment pictures soon.
