Not necessarily. While I do encourage Diana to get a chiller, it really depends upon doing some research on collected species. If you look on this link http://hmsc.oregonstate.edu/projects/msap/index.html you will see some of these critters have 23 C as average temp. Thats 73 F. This should make some local livestock possible to keep at room temp.

Ok here I come!!!
 

First of all love your pics and the tank!!!! Since you took every thing out of the ocean you do not have to cycle the tank. The sand is already live and the water is fine. Only thing is make sure you get the local ocean water readings so you know what kind of water you have to mix up later.

I have found that there is quite a bit of water difference in the local ocean waters. For example the water in Stanly Park will be different from Wite Rock. Try to get your tank mates from one location then it would be eassier for them to live together and also the water issue should be solved.

You should try some Ananos they are cool to watch. I found Stanly park is a good place to colect them. Hermit Crabs can be found at Wite Rock when the ties goes out and good place to look for them is on the sea weeds. The snails are also good for cleaning.

Good luck with your tank!!! :biggrin:

P.S...
 

P.S: Feeding those green gobies are hard some times. I found that they only eat something that is moving in front of them. I found that when you feed your crabs the green gobies will fight with the crab for food since the crab is moving the food around. Is realy neat to watch.

Cheers :biggrin:

I would do it! Haha.

or if you have a small bar fridge you can cut out the hole in the seal and drop it in and have a tub in there with a ower head and then have it connected to a line and back into the tank.

OMG I JUST THOUGHT OF A GOOD DIY.

p.s looks wicked.

Just a little update. Ive added lots of hermit crabs and regular crabbies, and some anenomes! I will have to get you guys some pics, but i picked up a few little tidepool anenomes (they have orange stripes and whiteish tentitcles) that are so far doing fine. One is even living on the glass, which is neat to see its insides. :mrgreen:

That would be so cool to go out and collect the stuff for your own tank. Stupid freshwater province.

Looks nice, but calling it a cold water tank at that temp is a miss use of terms :mrgreen: I just looked you can get a 40 degree pull down with a 1/5 hp UMI chiller or a 1/4 hp Pacific coast chiller.

just the fact that none of your barnacles or mussels are open and pumping is an indication that it is to hot for them. they think the tide is going down because of the increase in temp and are staying closed to preserve there moisture when they tide is low and they are exposed.

Who said they werent open and pumping? All my barnicles are feeding, more-so at night than during the day (i guess thats more natural for them?). The mussels are also open as well. ;) I am feeding the barnicles frozen baby brine and plankton. I know they are eating it since i notice a rise in thier activity after i feed them.

what are the odds of getting some more pix. I for one would love to see the tank as it progresses.
