actually i agree with boss, once you start, you can never stop (unless decomm or all livestock dead).
lets say even for fishes food, new life spec big bottle already cost $30. constant water changing and electricity bill.
(not really deep pocket), but if the TS wanna start reefing, its better to have a income / CFO to sponsor the TS into a marine setup.
Those little tiny thing (test kit / additives / live stock) cost.. though little, but as times goes by , it add up to quite a sum (i started a excel sheet calculating all the things i brought )
my 2 cents, all the best to you TS . consider wisely.
cheers.
