Hi everybody. This my first post. I have been keeping tropical freshwater fish for over 10 years. I currently have two tanks, A 180 litre planted aquarium with CO2 canister etc established for 2 yrs. I also have a 260 litre Vision 260 juwel aquarium with a single black tiger oscar having taken up residence for the last 4 years.
I am moving into a new flat and am forced to sell one of the tanks. I have to drain the the 260 to move it anyway and a friend of mine has always envied my oscar. I have always wanted a marine tank so I was wondering if it was possible to convert the 260 litre tank into a marine. Or does the fact that I have had freshwater fish in there for so long prevent me from converting it.
I know I would need to upgrade the lights. set up a sump and skimmer and get a new filtration system but I figure this will still be the same cost as buying and setting up a nano. Or do I sell the tank and start saving a long time for the redsea max 250d that I think looks so stunning?
Hi nith, it all depends on what you want to keep in a marine setup. If you have ever dosed any copper based medications to these tanks you won't be able to keep invertibrates as some traces will always remain. This will leach out of the silicon joints and kill these sensitive creatures. For fish only or fish only with live rock (FOWLR) it will be fine if meds have been used. Whatever you decide, take your time and do lots of research first, and ask lots of questions even if they seem silly.
