Well after looking at my other tank journal http://www.masa.asn.au/phpBB3/viewtopic.php?f=148&t=219890 and reflecting, I realise that it has been 3 years since getting into the marine side of aquariums. So I guess this upgrade is due. I have been mentioning/suggesting such an upgrade to the wife for the last 2 years with not much luck. So I was surprised the other day when out of the blue she started asking questions about a bigger tank.
I’m not an idiot(can be debated


Also realised how out of date my details for the current tank journal is. Will try to be a bit better with this one. Not promising though

I must admit I am pretty excited

Here are some planned tank pics


Finalised stand design.

Planned Sump design. What do you think? Bigger? Changes? Ideas?

Planned tank design/dimensions. Thoughts, Concerns?
The idea of the deeper overflow is that there will be an acrylic sheet for the weir and this will have slots in it lower to facilitate water changes through on of the drilled holes. You can see the idea better in the complete tank stand picture.

Thanks for looking. Getting excited
