Flashy Fins Posted April 4, 2017 Share Posted April 4, 2017 The live rock contains the majority of your bacteria, so once your larger tank is emptied out and filled with saltwater, you can take your live rocks straight from the old reef tank into the new one. This will avoid the cycle a brand new tank with dry base rock would go through, although it will take a little time for bacteria to populate the glass, sand, etc. I can't tell if you have sand in the reef tank, but if you do, you might consider buying new. Stirring up old sand beds can cause a lot of problems you wouldn't want to transfer over. Although, it appears you might not have any sand in there.

milesmiles902 Posted April 4, 2017 Share Posted April 4, 2017 Unless you want the protein skimmer in the main tank, you have to drill an overflow or use one of these: http://aquarium.bulkreefsupply.com/search?w=external overflow&asug= Otherwise, just figure out what you want to put in the tank and build it around that.

Higher Thinking Posted April 4, 2017 Share Posted April 4, 2017 No, you can't just add salt to an established freshwater tank and choke out with an established saltwater tank. Different bacteria for each. You'll have to start over from scratch. And you won't want to run the canister filter on a reef tank.

pdxmonkeyboy Posted April 4, 2017 Share Posted April 4, 2017 you can absolutely run your fx6 on a saltwater tank but you will have to clean the filters every week Sent from my SM-G930V using Tapatalk Quote Link to comment Share on other sites More sharing options...
