Hi ticketyboo.
I've been experimenting on and off with a coldwater/temperate system for about a year and a half now. Here is a link to my thread. http://www.canreef.com/vbulletin/sho...ight=temperate As of now I have suspended the SW tank and am housing coldwater FW fish in the system instead. I did this because the set up became more complicated than I anticipated and I want to work out some stocking kinks and expand on the system. By stocking FW fish I can keep the tank running and track my temps through the summer. I intend to build a much larger refugium to breed microfauna and as a means of nutrient conversion. I was thinking of surge tanks for low heat input circulation but might also work on airlift pumps instead. I am also toying with the idea of a Jaubert/Monaco style filtration system if I can determine that enough dentrivores are available at lower temps. Even with every known way to reduce heat inputs (no submersed pumps, cool lighting, sump on concrete slab) the system will require a chiller to keep true temperate species like the ones you are suggesting. I have tried everything to drive my temps down passively but by summer I expect the temps to be in the mid to high 60's. My current tank temp is 56*F. Stocking is complicated and requires a well thought out plan. Originally I built a large skimmer that works very well but I then found it to be starving my clams, oysters, barnacles and other filter feeders. On the other hand many meat eating inverts that I like (starfish, sunstars) and fish create a lot of waste so skimming is required. 6 of one - half dozen of the other? Many of our local fish will also only take live food so one has to be prepared to provide phyto plankton, zoo plankton, copepods and other microflora and fauna either by live capture, expensive store bought or a very mature system. What are your fish feeding on BTW? There is a thread on RC that deals with this subject as well. I'll try to edit in that link. http://www.reefcentral.com/forums/sh...hreadid=890751 Look for me out in the big pond soon as I am taking a SCUBA course next month  Last edited by Dale; 03-06-2007 at 04:13 AM.

Best diving locally is Vancouver Island, Campbell River, Barcley Sound, Gabriola pass, wow... I sure miss it all. I used to be an Instructor in Vancouver, saw lot's of people go through the courses, most loved it. We really do have some excellent sites here, sadly I've seen a lot of sites die off as homes are being built and sewage is being dumped raw into our waters.

Hey, thanks for the lengthy reply.
I got some stunning nudebranches today on my dive... although im not sure whether that was a good idea or not... but its all experimental just now. If you want to go dive let me know... im a DM and could show you the sites... I also got a buffalo scupin but i lost it as my collection net was too loose :-( it was a cute fish.... 46 degrees today though and i was cold so i called the dive. pics to follow....

I did my recreational dive courses for 300$ for the lessons. Plus another 300$ for personal dive gear (fins, mask, snorkel, gloves, boots) that you keep yourself. You can get more expensive nicer looking gear but used gear like mine works just fine.
In April Im going to start my "scientific diving" with the aquarium... now that's what i call job satisfaction.

Also you can volunteer at the vancouver aquarium to be a diver which allows you to dive in the tanks with the sharks etc... minmum of a rescue diver cert is required.

Sweet
I have always wanted to dive, and I do a lot of travelling but cost is a big thing. That aquarium thing sounds pretty sweet. Kris

I don't think we would let a volunteer dive with the sharks... we have aquarists to do that. However I know that you can volunteer dive for our research department. I think all you need is a recreational dive cert. No need to get a rescue dive cert.
hey do you think we could see a few pics of your nudis? I love those guys. I think the alabaster nudi is numero uno on my list.
