Hi folks Paul here, last had a freshwater tank 20 years ago, Decided the time was right to get back in, All in the planning stages at present ,but designing a custom 1500mm x 500mm x600mm tank, Plan on using Fluval gear thoughout ( never had issue with thier gear in the past), will be a sand bed, hope to have a couple of sand waterfalls ,. Everything possible apart from the heater will be externally monted.
