it's difficult to get a 2nd hand chiller... how to have a convinient 2nd hand chiller lying around to chill a 183 gallon tank? the after sales service is good. is just when he doing it that time, probably did it with some mistake because we cannot test it there and then without the thermostat and the tank running.
will arrange with him to come to settle the problem on monday.
i want to get everything done with ASAP so i can put the tank set up behind me.
anyway on a brighter note (pun intended), the lights are up.
no chiller = no lights. so they will be turned off for now.
