I believe he mentioned reef tank.
The corals, inverts and fish you wish to keep can/will determine certain things you may want/need.
Below i will go over a list of key elements and rough price ranges. Price is dependent on quality usually in this hobby so be prepared to pay more money for the good stuff and things that will make your life easier such as a controller for example.
1) Tank - largest possible gallons is recommended. More water = more option and more room for error. Stay away from anything deeper than 30 inches. Most lighting has trouble penetrating deeper tank and will require specialized lighting. 36" wide limit probably will require a cube tank if you want anything over 40-50g so the marinland you looking at might be the ticket.
2) Live rock - many types of live rock but most popular seems to be fiji, pukani and tonga(export ban) if you can find it from a reefer. Expect live rock to go for about 6.99-7.99 per pound at most LFS
's. 1 pound per gallon is recommended for a reef tank. Also many cut the cost here by getting dry rock and a small portion of live rock(25-50%) to seed the dry rock with. Dry rock is much cheaper at around 2.99 a pound.
3) Lighting - lighting is one of the most important aspects of a reef. The lighting you will need will largely depend on the size of tank, how deep it is, and what corals you are planning to grow. Sps
, clams, anemones will require more intense lighting, get back to me on this and i can make some suggestions. Also you need to decide if you want metal halides, LED
's, or T5's. Prices will range from a few hundred to a grand or two.
4.) Sump - a sump is not require but it will allow you to do more and give you more options when it comes to filtration and making life easier. The largest size sump you can fit under you tank is recommended. Also with a sump you will want your display tank to be drilled and fitted with a proper overflow box. Sump can be self made DIY project from a smaller tank.
5) Skimmer - skimmer is you best piece of equipment for maintaining organic matter in a reef tank (besides water changes). A skimmer rated at double your tank size is recommended. Cheap skimmers usually come with cheap pumps so expect to pay 200-500 for something that will do the job well for a 90ish gal
like i think your planning.
unit - you do not need to buy your own unit but it is cost effective and will pay for itself within the first year. Ro
water is highly recommended for reef tanks for many reasons. A good unit can be purchased for 150-200 usually.
7) Heater/Chiller - living in canada you likely to atleast need a heater. Usually chiller is only needed for hot tanks from halide lighting for example or in a hot climate. Heater will go about 30-50 bucks.
8) Powerheads - atleast 2 are recommended. The size and how much flow you need will depend on tank size and corals u wish to keep. Koralia's go for about 50-100 depending on size and the high end Vortechs will fetch hundreds depending in size.
This is the equipment you will probably require above. Below is a list of possible equipment you may want or need in the future.
Stuff like this can always be added at a later time if wanted or needed easily.
Accessories are many but below are a few you will need to start:
Test kits (ammonia, nitrite, nitrate, ph, alk
, calcium, mag and phosphate)
Airline tubing (for acclimation)
Hopefully this should all get you started and researching. I cant stress reading as much as you can enough. It can be a very tough and expensive hobby if your not informed.
Also do NOT i repeat do NOT let fish stores try to sell you things. As you can see this hobby is expensive and LFS
's often take advantage of that by selling unknowing buyers things they do not need or that are junk for what your trying to achieve. Someone here at AA will lead you in the right direction as far as what you 'need' if you have any questions.
Hope that all helps.
