Thank you for the replies. I did not add a bubbler, which I have one on hand.
I showed my landlord the tank and he has a similar setup but a larger tank. He said they do fairly well and gave me some tips.
His tank is 15Gal with coral gravel and under gravel filtration with normal hood lights. He keeps it in the lower section of the house in a closed cooler room. With a small power head.
His daughter has a 30gal tank with no filtration, a power head and it does well too.
I set mine up yesterday (Tuesday). On Monday I picked some oysters and had them in the fridge in a bowl. In the bowl on Tuesday night (about 30 hours after harvest in the fridge) there where some small crabs and limpits. So I tossed them in and they seem to be okay. I tossed in a piece of Mussel and the crabs where eating it.
The Tank is 10 Gal
and has LED
lights, and an in tank filter (rated 2-15Gal) with no filter (used to add oxygen and it adds a small current) It has Fucus, eel grass (two shoots) and some sea lettuce and some other algae.
It has lots of hiding holes and I tossed in some various sized snail shells.
The tank right now is about the same as water level in local tide pools and the critters seem to be happy. (which may change) I am going to keep a major eye on this tank. I check temps every couple hours. even a couple times at night just to see the temp drops. So far temps are all safe as far as local waters go.
I might need a chiller in the summer peek heats. My land lord suggested the soda bottle with ice method due to the tanks small size.
I will update every wednesday. I do not plan to add any fin fish. I need to check with Department of Fisheries first, if o.k
.ed tide pool skulpin and stickle backs.
