Ok opening this thread coz I'm sure I've seen this statement very often being made to guys here (DONT add too much livestock all at once to a system) Now is there a formula that one uses to see how much of livestock one should add into a system and in what space of time? We are told 1 or 2 fish at a time every 2 or 3 weeks coz the bioload has to catch up! Who knows what the bioload is at the time of putting the fish in? Also livestock means any livestock - this means corals, liverock, livesand and is there diffrent time periods for the different livestock and depending on the amount of each different livestock? ?The short and sweet is - how do you work out how much of livestock your system can handle at any given time considering - water volume,space,tank size, sizes of livestock? Dont get me wrong everyone - I'm not bucking the system but I'd like clarification as to how one works out how much livestock to add for mine benefit and all on the forum
