Can I do 4-6 inches of live sand with live rocks?

The guy at the pet store told me I could use a saltwater
filter I would just have to change it more often
because the food/poop is it possible to use 2 really good
saltwater filters and with regular water changes maintain
a healthy tank?

I heard more of the live sand helps lower nitrate levels.

what is a saltwater filter? i think ( and i could be totally wrong ) your talking about a canister filter? a canister filter is not a saltwater filter. the only saltwater filter they make is a protein skimmer. a skimmer doesnt catch debris like other methods of filtration do though, making it the ideal "saltwater filter"

a normal filter, whether it is a hang on the back of the tank kind, canister kind that goes under the stand, or even a sump full of bioballs is not the way to go when setting up a saltwater tank. if this were a freshwater tank, then yes any of the 3 mentioned filters would be great.
a skimmer on the other hand does not directly catch poop into a mesh like surface, which does not give it the chance to break down and polute your tank water. it basically gives the water a nice whip and allows it to foam up into a collection cup.. the foam contains the poop and un-eaten food which is extracted from the water. (opposed to the freshwater method that allows this to sit in the tank water and have a chance to turn into excess nutrients.)
you can, use a "freshwater" filter but it will require cleaning every other day or so to not notice a NEGATIVE impact on your tank. i personally would only use a canister filter completely empty ( just for water movement, but thats what powerheads are for ) or to only run some carbon in ( but thats what media reactors are for ) so honestly you do not need this piece of equipment.
if this is infact going to be a 2 clownfish only tank, i think you would be fine without a filter, or skimmer for that matter. i personally would run the skimmer in an oversized sump because i like water volume, but thats just me. if you pre-mix your saltwater 24 hours in advance and stay ontop of water changes, that will be enough filtration. ( granted your tank went through its diatom bloom with enough pourus live rock and sand already ) and theres plenty of flow.

i was trying to find an article ( i believe by pasfur ) on fresh vs salt filtration and couldnt. if i come across it i will share it with you. i did happen to find this, which touches on some issues of saltwater filtering.http://www.tropicalfishkeeping.com/s...ncy-bio-47415/

I'll buy a protein skimmer then.

How do I pre-mix saltwater do I mix in a bucket or just in the tank and w8 24 hours?

How long does it take for a 40-75g saltwater aquarium to cycle?
After setting the tank up I was going to w8
a couple months to let the tank settle just
to be safe is this okay?

they do make hang on skimmers, i have no experience with them however. i do know that if the skimmer is the route you wish to take, read online reviews about them.. alot of skimmers just make noise and waste electricty ( in other words, they are garbage ) while some are better then gold.
i do think you can pull this tank off without the skimmer, but having one will only help.

as for the cycle, it will depend on alot of things. are you buying fully cured live rock? you may not have much of a cycle then. you will have some die off, but within about a week it should balance out. this doesnt mean its ready for fish just yet. are you buying dry rock? this will require you to cure the rock yourself, which basically just means letting it be in a tank ( or bin ) with saltwater for about a month or two.. adding a few pieces of live rock to the dry rock "curing" will help with the process. this usually is a much cheaper route, but takes more time.

you'll want to pre-mix your saltwater in a seperate tank/bucket/large food safe container with a heater and powerhead atleast 24 hours ahead of time. the very first time setting up the tank, you can do it in the tank ( when theres nothing in the tank, no rock, no sand, nothing! ) but thats it.. after the first time, mix it outside your tank. it would also be wise to use RO/DI water, which is pure and will not add anything to your tank you do not want. this helps keep bad algaes at bay like hair algae. if your not introducing phosphates, its tough for something to grow that feeds off them.
an empty tank may need to be "fed" to keep the bacteria from the cycle ( the good kind that you want ) alive. this would really depend on how long you want it to be empty for. the ammount of food you would need to add wouldnt be much either. you wouldnt want to foul the water before even having anything in it. this would start to smell.

here is a very basic guide, but a good place to start

this is ok, but it can add up in cost in a short time. an alternative would be to purchase a RO/DI unit and making the water at home. the unit will cost a couple hundred up front, but long run your not paying the estimated $.50 - $1/gallon. just another thing to consider.
