Hi so I'm getting an upgrade but not sure if I want the 80cm 45 or the 90cm 45, I will also reinforce the shelf later but my shelf is 91cm SOLID and is really week, it already has 2 10 gallons on it and these fine, one salt one fresh, the problem is if the tank is 90cm would weight be I issue I will give pics of stand later also underneath I also want a Large refugium/sump, around 70cm or 90cm long and it would be a 50 or 60cm refuge part in the middle, no skimmer and mostly depending on natural filtration, anything would be appreciated, plz excuse the ugly tank, went away for 2 weeks and all corals that survived were some pale zoas. I'll give tank listings in another post but remember I will be removing the lower wood support and replacing with 2x8s
