I used to convert a 5ft marine tank to a FW tank keeping aro. Actually it is very easy, since the equipment we use for marine can be use for FW as well.

Q1) how to remove the coralline algae? Those purple color one that growth on the back of the tank.

- wash with freshwater and scrap away with a brush

Q2) can I still use the tank for fresh water?

- of course you can, but you need to give a good wash to the tank first.

Q3) how to clean and ensure all my equipment(filter/pump) salt free.

- wash with freshwater and soak equipment in vinger or DD EX Clean to remove any particles or coraline algae if any.

Q4) how long must I recycle my tank before introduct fish?

- The tank cycling process is basically the same for setting up a marine tank.
