21st day of cycle

Today marks the 21st day of cycle.. Meaning its 3rd week.. Time for a water change.. Did a 30%~40% water change on both partitions..





Auto top up system at work.. Water used is RO DI from 6-stage RO DI system...



Now for the last boost of liquid bacteria before commandos test shrimps are going to go into the tank next week... And this is what I am using..



There are 2 vials inside each 'tiny' box.. Just right, 1 vial per partition..



Here it goes.. The vial's content is going in...
And I will be placing the empty vial inside the tank to make sure all the solution or residue is all In..





Now wait for the tank to be filled up.. Tweak the TDS to my required reading, and next will be testing for ammonia (might not need) and nitrate...

Stay tune.....
