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.
Well, two days after we left I got a phone call from my security firm - telling me my power has tripped. So I sent some people over to have a look - and there it was. 480g of saltwater on my living room floor - flooding everything. The tank cracked its double 10mm base lengthwise - a 2.7m long crack. It took a couple of minutes for all the water to leak out.
When I got back Exotic picked up the tank to fix it. They replaced the broken base with 3 x 10mm panels. Extra bracing was added to the square tubing stand, and the metal is both thicker and bigger. Hopefully this time it will hold that water. I am expecting it to be delivered early next week.
In the mean time I am struggling to keep my current 400l FOWLR tank happy. The Nitrates are through the roof and water changes does not help. So all I can do is wait...
