I built my own corner tank, sump, atnd and lid!
I was studying for my HNC in Electronic engineering, and the company I worked for wouldn't let me do my project on their technology (Trade secrets etc....) so I PLC controlled my tank instead!
pH, Salinity, dissolved oxygen, water levels, temperature, water leak detector and even a power-outage alarm!
OH eventually wanted to redecorate and the stone-effect paint didn't match, so she told me to get a new tank!
So I opted for the bow-front corner tank, drilled it, took out the centre bar of the frame, re-enforced it and sumped the tank!
Tank is now in storage awaiting shipping to BC!
Jeez! I miss my tank!

ps. I use relays now! Sold the plc on Ebay to fund my salt addiction! lol
