Thanks for the sump tip KS, I'll look into that. My current sump is a rubbermaid while I build my drilled permanent one (for the inline return pump) so I'm good there for now.
As for filtration I can only say again that the best plan is to work backwards - the species will determine what is best. My first foray into collecting taught me that. I gathered some macro algae, hermits, snails, barnacles, clams and oysters. All went well for awhile then the snails began eating the macro, the hermits attacked the snails and the barnacles, clams and oysters began to die off and foul the tank. In retrospect, I don't think I could have kept a new set up dirty enough for those types of filter feeders. My sober second attempt is going much slower but is much more satisfying. I am plumbing three tanks together to create a display, refugium and sump. I have about 70lb's of LR cured at cold temps now with another 80lb's or so on the way. At the moment the system is housing a school of redear sunfish (a local FW species). They are nice fish and allow me to see how the system will function before converting to SW. The current tank temp in the garage without a chiller is 61*F (with a temporary submersible return pump). With the pump turned off it's 56*F

I used to keep those when I lived over there. As well I had black crappies in the tank. Neat fish, easy to keep. Shaun. Last edited by fishmaster; 04-12-2007 at 03:43 PM.

Stupid question, how cold does a cold water tank have to be? My basement will keep standing water at 66F no problem.

Depends on what you call cold water.
Conventional thinking is that subtidal species from our latitude will probably need temps with an upper limit of 55*F or so. You may get away with 66*F with some hardy intertidal/tidepool species as they are used to greater temp fluctuations (but they do get a regular drop of temps when the tide comes in) while some species like the three spine stickleback can take higher temps in the mid sixties. It all comes down to livestock selection. I toyed with the idea of keeping a tank at higher temps (without a chiller) but by now I am convinced that one is needed to knock the temps below 60*F at least. In your case a small chiller combined with reduced heat inputs and evaporative cooling might be all that is needed. Last edited by Dale; 04-12-2007 at 11:01 PM.

I toyed with a cold water tank a couple years ago and posted some research results at the time.
In short, I contacted the DFO and was told collection is legal with a fishing licence and you must observe quotas. (The exact email is somewhere on this forum if I remember correctly.) As for temperature and species selection, I found this a great site for potential species. http://hmsc.oregonstate.edu/projects/msap/index.html And for insperation, http://www.racerocks.com/ Hope this helps. Hmmm got me thinking of doing this again. (And I blame you all!! LOL!)
