iv decided to go marine, and i am going go for a reef set up! i have chosen my new tank its going to be a Fluval Profile 850 in silver. its a 232 ltr tank with a Fluval 205 external filter.
my questions are.
1 am i right in thinking about 25kg of live rock would be ideal for natural filtration?
2 will i be ok instead making my own water getting it from my lfs
all of the time for water changes?
3 should i get a constant flow wave maker or one that changes flow on timers? and how many litres an hour will be ok for the size of tank?
4 do i realy need a protein skimmer as i have read that they do ok with out them because some sort of bacteria will eventually play that part?
other than the ammonia,nitrite,nitrate what other main things will i need to test for a heathly reef system?
what is better crushed coral or live sand and what size would be best?
i will be getting the tank in the next 5 weeks as moving house so thought its best to wait just doing my research in the mean time! as always knowledge is power! thanks ryan.
