Hello all I am very green at this to any help is kindly appreciated.
Had by chance found a Aquarium Store, which is not very common in my part of the world, they had a really brilliant marine tank so I thought I would try to emulate theirs. The sales lady convinced me it would be really easy to do. So, I bought the second largest tank in the store :$ So I have a 1.5m (I think approx 400L ) aquarium that has the filter and case and lights for about only 350USD. She said the only extra equipment I need is the protein
skimmer and the UV sertilizer, I am assuming that the heater is built in and I didn't ask.
The tank get delivered next week, I have been reading on the topic the last two days and this is what I have decided. It will be a
FOWLR system, they sell
live rock at the store. I will have 2 Clowns, 1
yellow tang and 5 or 6 Yellow tail damsels (basically identical to the display

) they already sell these at the store and i have reserved the damsels already, prematurely I now know but were too cheap about 3USD each (I will have to back to make sure they dont deliver them with the tank).
Do I need to set up a
sump?, Do I need a
RO system? Would like a dark substrate, any recommended? I want to place the tank on an upperlevel my home is made of concrete and stone is that ok? How long does it take to cycle? I am really unsure if the equipment neccessary is available to me as most things on the net are US based or UK.
Any direction is appreciated before I head back to the store.
Thank you kindly.
