@everyone - thank you again for the warm welcome and kind words. Truly appreciated.
I will try and collect whatever information I've gathered and what plans I have and start a build thread for my 240 gallon upgrade. Probably close enough to start and maybe it will even help me stay focused Rock is in tubs at the moment outside while I dose phosphate remover and wait for substrate and a test kit to arrive. I'm one of those lazy reef keepers who really don't test water parameters much so my last one has since expired - embarrassed to say.
