Hi - Name's Paul. Live over in San Diego county, and am a teacher.

In the process of setting up a "local marine life" aquarium using local items only - Sand, water and rocks all collected locally while in the water. No animals yet, other than whatever hitchiked in with the rocks/sand. Tank is a classroom tank with everybody working on it and is/will be incorporated into various lesson plans.

120 gal with about 65 gallons in it so far, 100 pounds of live sand, 60 pounds of live rock. Will be getting about 40 more gallons of water, and some more rocks today. Putting in another powerhead to move the water around some more while it cycles/settles. Still looking for a good protein skimmer.

Not 100% sure I will keep an octopus in there since I'm not sure my students and I would be able to provide the attention one requires. Will start out with other items first and see how that goes.

-Paul

:welcome: there Paul. The tank looks jolly good, but ..... I'm just a little worried about that stand; it seems rather high and flimsy for that weight, for a glass tank, especially around kids. (Any experience I've had with 'tables' like that is that the welds are prone to breaking and/or corroding; have you got a honking big cabinet somewhere [made out of wood as opposed to chipboard]that you could put it on instead, against a wall?)

You are going to need a chiller to keep local marine life. I kept local Southern California animals for 10 years in Long Beach. I had no problems with any animals unless my chiller broke down, then everything perished. I ended up always having a back up chiller. Do you have a collecting permit to collect animals?

:welcome: and good luck. Let me know if I can help.

At least here in NZ, most rock pool animals generally do ok in a non chilled tank. Some of the fish may be more temperamental, but on the whole they will survive easily if the temperature is kept under 72F. (It might be different in California though!)
Chillers are very expensive, and with a tank that size it would be at least(likely more) than $600US.

However there are some cheaper methods of keeping the temp down, starting with making sure the tank is out of the sun. You can also run a household fan above the water but it will mean you need to top up with fresh water more often.

Good luck!

:welcome: and I second what Steve said about the stand! We've just replaced all the stands in our teaching lab with heavy steel and wood ones!

Yeah about that, so, am I not the only one who has had corrosion around things that were just near the aquarium plumbing then?

Sorry to hijack the thread Blesum, it's just this has been bothering me lately w/ my tank. In my defence, this info will aid you as well from the looks of things.:wink:
