RH Fish Tank needs 1.5L bottles

We need about 14 (or more) 1.5L bottles. Please:
1) Rinse with tap water a few times (do NOT use soap)
2) Put clean & empty bottle inside the white cabinet next to the RH Fish Tank

I will label each pair of bottles "Monday, Tuesday, Wednesday, etc" then fill them up, leaving them inside the cabinet.

What we need to do is...
1) use the bottles labelled "Monday" to top up the RH Fish Tank on Monday
2) fill up the empty bottles with tap water
3) put the bottles back inside the cabinet
4) allow the chlorine (harmful to fish) inside the bottles to evaporate
5) repeat steps 1-4 with the respecively labelled pair of bottles per day
...a checklist will be put inside the cabinet to record the topping up.

Leaving the bottle capped but not tightened (turn the cap a few rounds to ensure water trickles, not gushes, out if upturned) allows the chlorine to evaporate from the water. After one week of letting the water stand (bottles untightened) the water will be suitably de-chlorinated for topping up the RH Fish Tank.
