First Milawi tank

Hi

I have kept marine fish for a few years now, but have never got involved in fresh water tanks.

We have a fesh water tank at work but noone has been looking after it and all of the fish have died. I have recently been asked by my manager to get it up and running again and thought a milawi tank might be the best option.

It is a 3x1.5x1.5 tank with a fluval 304 canister filter and an air pump in the display tank.

As I will be looking after the tank i can bring in RO water from home for water changes, but is there anything else i need to think about?

Is the equipment ok for Milawi or will i have to upgrade?

Thanks

Dan
