prreefman,
How are you doing, Joisey Boy?
You have a lot of questions, so let me start at the beginning...
1. Do a water change on your home tank and use the waste water to seed your new tank. Also, some sand from your home tank will help with the cycle. if your home tank has crushed coral, put some of that into a stocking. Place to stocking of CC into the new tank. That will help spread the helpful bacteria to the new tank.
2. Decide what type of filtration you want in this 75. You have 2 choices - live rock or a wet/dry. You really have other choices, but I recommend you stay away from mechanical filtration, like the Fluvals. If you go the live rock route, your tank will cycle very quickly. Maybe a couple weeks or even less. I cycled my 55 Fish Only with a wet/dry many years ago and it took 7 weeks to cycle. I do not remember off of the top of my head what brand of wet/dry I have. It is a hang on model, however.
3. What are your plans for a sand bed? Just enough to cover the bottom glass or do you want a deep sand bed? The DSB provides a home for a lot of beneficial critters. A DSB is usually 4 inches deep, but it can be deeper. 50 pounds will cover the bottom. If you are interested in a DSB, do a search on this board for "calcul
ator" (I think). A post on this board will provided a link to reefcentral that has a DSB calculator. You will need the measurements in inches to put into the calculator. Please do not hold me to this, but I would imagine you need around 150-200 pounds of sand.
4. If you decide to use live rock to filter the tank, you need a skimmer. I have skimmers hooked up to both of my 30 FOWLR tanks. If you use a wet/dry, you should probably have a skimmer. It depends on your bioload and what you have in the tank. Having a skimmer in a heavily stocked tank with some big waste producers (triggers, for example) is a mandatory requirement.
I have been running my 55 FO for 11 years now and do not use a skimmer. I do do water changes every 2 weeks and do not have a heavy bioload.
HTH. If you have othe rquestions, drop me an e-mail.
Regards,
JohnD
