So, I got a new tank.

Just got another 4 foot tank, works out to 37 UK gallons.

I already have a reef setup, 20 UK gallon tank, I was wondering what extra I would actually need to switch from the 20 to the 37 tank?

Other than the obviously needed sand, I currently run a koralia one powerhead which puts out 1600LPH.

Also running a 600 l/hr filter and a 250watt heater.

Any ideas on what I would need to purchase/upgrade?

I would say not much mabey a T5 light 4 bulb min and some rock should do you fine And another power head though you may find that you have enough water movement all ready
