I have had a 14 gal bio cube for the last 5+ years and I am thinking about making the jump to a much bigger tank. I am thinking about going used to save thousands. I found a tank that is working, but appears to be filled with slime algae and who knows what else I will find when I look in person. My question is: how much effort will I be putting in to get this thing functional. Will I be strapped with nasty diseases forever and will it be worth the "savings"? Link to tank: https://offerup.com/item/detail/564834272/ I have learned from research it is an Aqueon 72. Not sure what all was done to get to functional for salt or if the lighting will suffice. I assume it will. Will be interesting if this tank that been for sale for over 3 months sells "all of the sudden"
