Hello *Wave* and welcome
Ryan DAD
First of all congrats for asking the BEST possible question you can when starting out. The more you research, know and understand before you get started the better off you, your tank and your purse will be. It's easy to make a LOT of mistakes early on.
Please know that what works for one particular tank may or may not work just the same (or at all) in your set-up. There are bad ways of doing things, good ways and then of course there's Allens way LOL! Just kidding!
Spend some time at our LFS's and ask questions as you see things. Look online and ask lots of questions just remember a LOT of what you read online can be "iffy". Take it all with a grain of salt and research Research RESEARCH!!
One of the single most important aspects of ANY part of Salt Water (Fish Only/FO, Fish Only with Live Rock/FOWLR or a full blown Reef) is learning the Nitrogen Cycle from every point of view. It's intricately linked to everything happening in the tank and the more you know about it from the beginning the better equipped you are to recognize and deal with any "Cycle" issues.
When it's time to buy I like to tell people to buy the largest tank that:
(Larger IS better with SW tanks.... more water volume = more stable environment = easier to take care of)
- * A) Will fit in your living space
- * B) That you can comfortably maintain
- * C) That you can afford to buy AND Maintain.
Once you've picked out the tank and start looking into equipment think/plan Long-Term. Try to look at other tanks and see what you think you'd like yours to look like in a year or so and buy/build according to that plan.
When you DO buy equipment don't skimp. Saving a few dollars on "Life Preserving" equipment isn't the best place to save money. Many times with SW equipment (up to a certain degree) you get what you pay for. Ask around and try to get things that others are using and LIKE!!
Research each and every live-stock before buying. There are so many combinations of animals that it's very easy to puts things in these little glass boxes that wont get along LONG term.
Last but not least.... go slow. This hobby is one of patience (and lots of it). If you don't have it you'll be taught it and possibly the hard (insert money sounds here) way. The oceans where we get our animals are VERY stable and predicable and that's how the animals in them are designed. Everything needs to happen slow and on IT'S pace not ours. I like to tell people " You RUSH it... you CRASH it"!
Again welcome to the forums and please don't hesitate to ask questions. We enjoy helping each other out!!
Sincerely,
Allen
