Acclimitising the fishes

Will be getting the fishes from the fish shops at 2pm, then it's going to be the tedious task of acclimitising them to the RH Fish Tank water...

Acclimitising new fishes
Water from the fish shops (source tank) has a set of chemical properties which are different from the water of RH Fish Tank (destination tank); pH, Nitrate levels, kH, gH, Ammonia, temperature, etc. In the transporting of fishes from source tank to destination tank they would have already been through much stress (to be netted out of the source tank, put into the plastic bag, roll/sloshed around in the car, introduction into a totally new home, etc), we wouldn't want to stress them even further by giving them different water to adapt to, therefore we have to acclimatise them.
How to acclimitise the fishes?
1) Pour away 80% of the water that is inside the plastic bag (Estimate the amount of water in the bag remaining to be 2x),
2) Pour in 1x of RH Fish Tank water,
3) ...wait 10min...
4) Pour in 2x of RH Fish Tank water,
5) ...wait 10min...
6) Pour in 2x of RH Fish Tank water,
7) ...wait 10min...
8) Scoop the fishes out of the plastic bag using a net, put them into 100% RH Fish Tank water.

Introduction of fishes at 8pm
RH Hall Master, Resident Fellows, and JCRC will be putting the fishes into the RH Fish Tank at 8pm on Tuesday...
