I was just wondering...I never knew exactly how you do water changes in an Octopuses aquarium. How do you do it EXACTLY?? Do you take the octopus and put it in a bowl or something or a spare tank for a few minutes, and then dump all the water out of the tank and refill of it again? It seems like a LONG LONG process considering...setting up the water all over again. Like...after taking all the water out from b4...in order to make a new batch of water for your octopus...you gotta do the R/O unit system first....then you gotta fill in the tank slowly by slowly... Then you have to put in all the sea salt...and then you gotta keep testing and waiting to see if the sea salt is just right 1.026 or w/e. And then finally put the octopus back into the tank. It sounds like a tedius job...considering the stuff u already had in the tank too...like the sand and rocks and everything. So, is there an easier way of doing water changes? Mabye my imagination is too much...lol...I just was wondering. Setting up the water again seems to take a while...to put in the octopuses tank.
