You were right man bro. You have to start work one week before that to get ready pails, container and tubs to hold the live stocks and rocks. You also need to have prepare spares power heads for these LS and live rocks. Also, make order with Iwarna for 300L of DI water to be delivered.
Started work on the nite before the actual day. First decom the skimmer and the two FRs. Get them wash so that can pass to a nice reefer who bought the whole package including tank, sump, cabinet, razor led , skimmer, two FRs and chiller. After that, off chiller and return pump. Without delay, quickly pump the tank water into the ready containers followed by transferring the live stocks and rocks. This took me at least 3 hrs. Finally new tank cum cabinet arrived. Quickly with tank maker help, shift out the old tank and shift in the new set. After 4 hours, pipings completed and come the DI water from Iwarna. Added DD salt, checked SG and top up 50% of existing old water to reduce shock to the live stocks. Allowed run in for another 4hrs into the nite before putting back live stocks and rocks early in the morning.Suffered some casualties though but luckily only some common zoas and a few frags. Later late afternoon, the chiller man came to install the compressor cum drop in coil. That complete the whole excercise. Besides good planning and co ordination, you need a reliable tank maker, chiller installer and supplier, in this case Iwarna who delivered timely otherwise schedule will be screwed up. Is really a back breaking operation but good experience.
Cheers!
