I really can't think of anything, it's easier for me because I can take water from my larger setup which I know the parameters are very stable to do WC as well as using the same filter media that I already have on hand. Another point to note is that because it's so small, I keep my bioload very low ( 1 fish only , max 2 fishes). No clownfish, no tangs.. just a firefish for me.
The only thing I would not have bought is the cover as I ended up using eggcrate to cover the top as initially I thought my firefish would jump but then now I realise I don't even NEED the eggcrate!
This is actually not the end of my IQ5, my colleagues have requested for me to reset it up once we complete the move to our other office in October, so I told them see first, see how BIG is the table and whether I have enough space to put up my tank if not , I will set it up back home to put.. little things.
I will most likely change the scape a little with a different rock..
