help w/ 5 gal frag tank

[G.SMITHII]

so i want to set up a frag tank.

i just have this 5 gallon sittin around and this is what ive come up with.

in the 5 gal, just 2-3 levels of eggcrate glued in (so like shelves) barebottom.

gettin a nice aquaclear and jammin it full of LR ruble and macro algae.

a heater and a light. maybe a small power head too.





question is, do i really need this to cycle? or is kinda like a QT, plug and play status?

would i need anything else?

any feedback is greatly appreciated.
