My 10 gallon coldwater marine (yes for real) tank!
On a whim, I made a 10 gallon saltwater tank. I live in the Washington State Puget Sound area.
I went to the marina in Olympia, got me some water out of the Sound, collected a few rocks with barnacles and mussels and such on them, eight small rock crabs and a stickleback that was unlucky enough to get nabbed.
I bought a small hanging filter and bottom filter.
Four weeks have passed now. I've changed the water once a week, about 2 gallons at a go. Feeding has consisted of siamese fighting fish (betta) flakes daily (left over from a betta no longer amongst the living) and water turtle pellets. Crabs will eat anything, and between these foods I knew there was a fair variety of nutrients that are similar to what would be eaten in the wild). The mussels and barnacles suffer greatly for need of food, being filter-feeders. The barnacles are hanging in there but the mussels have mostly given up. The rock crabs - one survives and seems quite lively still: He's the only one that didn't crawl out and try a life as an apartment cockroach.
Temperatures haven't become ungodly hot yet except for twice, and those times I floated ice bags.
Yup, I know it's a brutal and crazy thing, but all in all I call it a good and cheap way to learn what works.
My next,
serious attempt involves building an intertidal coldwater aquarium with rising and falling water levels to mimic tides. It's all sketched out and on the verge.
