Restarting my tank

[aStRoBo|]

Here's wad i plan to do.

2ft by 1ft by 1ft(roughly), sump tank 1.5ft

1)Remove 2/3 of my present sand, or even all, and undergravel filter(yes i have it in my tank)

2)Buying 5kg 0 grade sand, 5kg grade 1 sand, scan it through magnet, wash it, pour into tank.

2.1)Brush my LR off with the algae and diatoms(if any).

3)Run tap water(de-chlorinated for 1day)Using red sea salt, mixed, LR in, re-cycle with market prawn.

4)Leave my sump alone, for mean time dun work.

5)Leave my FR alone too, dun think it's needed during cycling.

6)Skimmer off

7)Get all testkits ready

8)Wait until it's save to stock.

9)Putting in a SEIO M820 for my 2ft(too strong or just nice?) for circulation of water to prevent debritus to build up on the sand bed.

10)Sump, skimmer and FR back to work after it's save to stock.

11)Shld i get a sump same size as my main tank? or my 1.5 ft is sufficient?

Plenty help needed. thanks. Pls let me noe if i missed out any steps, or u may re-arrange my steps.
