Nano Cube Suitable??

[Halfsleeve]

Hi All im new on here so be gentle;) .
I currently run a 190ltr freshwater tank, but would like to setup a Nano reef, I have kept marines before so have experience with marines and I understand running smaller tanks can be a lot trickier.
Ok i have spotted a 40L cube tank in a LFS it come with an internal filter and a 18W light unit I believe its made by Aqua Qube is this tank suitable I really hope so as it will look great on my table next to the sofa.
Right from what I understand the internal filter is prob not needed, I will be adding a powerhead at least 3* the turnover of the tank is this correct?.
Live Rock will provide the filtration. Im worried will the light unit will not be man enough for the job as I would like to keep some soft corals(2 small clowns).Any advice welcomed.

you need 20* turnover as a ball park figure mate and also i would upgrade light

20 really?, that surely going to create a whirl pool practically.

18 watt of light should be ok for softies mate and bump the above for circulation!!

I've got 33x in my 24 us gallon cube (about 70litres nett capacity) and its fine

Ok say I go for the 40L cube, can someone give me a recommendation of powerhead(s) to put in this cube, also the same with the lighting(may need upgrading).I will be doing 10% water changes weekly using RO water.All advice welcomed.

You can use a maxijet power head - 30x flow with the 1200l/h

Cheers just found in my old box of fish bits a powerhead 900lph, so im thinking that plus the internal filter with filter wool and rowaphos (internal) should be a good combination. I also have from a small nano tank from AZOO a HOB filter, so again may come in handy with some filter wool to help clean the water, any thoughts folks?....
