Hey all I am planning to get my 125 gal tank today and want to know if a wet dry is the best way to go, or do I need a better filter?  I have a wet dry on my fresh water 55 gal tank that is about the size of a 20 gal tank is that ok for me to clean out and use on a 125gal SW tank?  I already purchased a skimmer its cost was $175.  I think its name brand is VENTURI??  The guy said it was good up to 250 gal so it should work fine for my setup.  Also what is the "cheapest" recommended lighting for this size of tank I plan to have fish and some "hardy" corals.   Thanks in advance for the help.

You should definitely plan to attend the meeting this coming Thursday. That is where you can find out about the most important part of keeping an aquarium - the filtration.

I know how tempting it is, but I would advise not setting up your tank until you have been to that meeting. You can avoid lots of expensive mistakes.

Briefly though, wet-dry is not the best for a reef but some believe that it is a good supplement for a fish only tank. Live sand and live rock are the best filtration media in my opinion. There is a free source of live sand called Oolitic sand in Utah. This discussion board has discussed it numerous times. Search for "Oolitic" and feel free to write or call me for help.

I think you'll find that most of the people in the forum don't recommend or use wet dry filters (nitrate factories as they're lovingly called).  You could pull out the bioballs and use it as a sump if you need/want one.  Your deep sandbed and live rock will cover the biological filtration.  Your skimmer will handle the mechanical filtration, if it's a quality skimmer.

I'll let someone else answer your lighing questions since I'm a Metal Halide believer and they arn't considered the "cheapest".  Enjoy!

The type of lighting depends on your organisms. Since you may not know yet what kind of organisms you will end up with, plan on using PC (power compact) or VHO (very high output) fluorescent with the possibility of adding Metal Halide (MH) later if you decide to have acropora and/or clams.

There are some advanced discussions regarding DIY VHO here on the board. Ballasts are available at Commercial Lighting here in SLC but the tubes must be purchased from the LFS or mail order. (this is where the mirrored aluminum spoken of in another thread is such a good DIY deal)

Natural sunlight can give the light that MH tries to duplicate. I'm waiting to hear of someone placing a large tank in the window or using a "light tube" to bring sunlight to the tank!

Now you're probably wondering between PC and VHO. PC are more cost effective but VHO can bring out some great color in the coral and algae. www.garf.org uses VHO. Check out their images.

For those reading this that are not able to afford these expensive lights, ordinary fluorescent lights can do great things. Check out my old tank pictures in the wesite "Gallary" I had six ordinary 40 Watt tubes over that tank. Four actinic, one white and one plant grow tube for bringing out the color (helps grow coralline algae too).

With regard to PC vs. VHO...  Look at as many tanks as you can using both types of lighting.  The advantage of PC is more lumens per watt.  Two 55 watt PCs (4' length) will output a little over 8,000 lumen while a 110 watt VHO (4' lenght) will output a little over 6,000 lumen.  I haven't seen/tryed every type of PC atinic, but imo the PC bulbs don't even come close to vho atinics (my personal asthetics).

If you're a diy type a person and you don't want to jump into MH, check out the fulham ballasts.  They'll power both PC and VHO.  You could use PC daylights (6,700K) and VHO atinics, and change down the road if you want.

Really you should check out as many tanks as you can before you decide.

jbruse,

IMO - LS and LR with a deep sand bed and a skimmer for filtration. Use the wet/dry but don't use it as a wet/dry- use it for a sump to house your skimmer, heater, etc.

As far as lighting goes -->  the tank is deep. Buy the most light you can afford. I have never had pc, but I love VHOs. Eventually, you will want to get metal halides - everyone does (even those who say they don't) (hahaha).
I think two 400 watt mh and two 110 watt VHOs would be perfect for the tank. What ever you decide - buy electronic ballasts. They will cost a little more up front, but they will save you in utility bills and bulb life.
