5ft fowlr tank

[marshalll]

Hi guys, have been out of the reefing hobby for 9years now.

 

This time, I am looking to convert my freshwater to a fowlr tank with mainly angels, tangs and wrasse.

 

Any gurus able to help give some tips and share any potential difficulties I might face?

 

Current tank is 140x70x50cm with a 4ft sump.

 

Will be reusing my brothers chiller for this tank.

 

Another question. Can I reuse the sand and media for the freshwater?

Welcome back to saltwater! Main issues with a fowlr(especially if you plan to have many fish) is parasite/disease management. Quarantine is great if you can afford space for another setup as your QT. Then again, even if you quarantine all your fish, there might still be a chance parasites get into your main system.

Personally, I’d absolutely recommend getting a UV sterilizer suitable for the volume of your main system, and run a flowrate low enough to make enough contact time with the water running through it to zap free-floating protozoan parasites like those of ich and velvet.

Installing a UV sterilizer has saved my tank from a marine velvet outbreak before and I haven’t looked back since. It may not eradicate the parasite from your tank completely, nor will it instantaneously ‘cure’ fish afflicted by parasites like ich and velvet, but it certainly helps to control the population of many parasites in your system.

Check out parasite eradication vs management on youtube. There are a few helpful videos to get you started, especially ones by BRSTV.

Hope this helps!

It will be good for you to decide what specific fishes you want in your tank.

For tangs, it is preferable not to have fishes of the same genus to reduce aggression. If you really want to have a few tangs of the same genus, providing more hiding places in live rocks might help. Some also suggests putting these in at the same time might help.

For angels, sequence of introduction of fish will likely determine if the angels can survive. Slow and finicky feeders like regal and majestic should go in first.

Hope this helps.
