I'm a truly freshwater aquarist, but my efforts to help my sister with upgrading her land hermit crab tank have finally brought me to this side of the forum.
I'm planning on building a saltwater pool for the hermit crabs in their new tank when we upgrade them, as they need one to regulate the salinity in their bodies and help with molting. They currently have one of those tiny reptile dishes with "saltwater" for hermit crabs. This isn't truly the saltwater they need, and that brings me to my first question. What is the best saltwater conditioner, or the one that you prefer?
Secondly- I have a question about filtration. I'm not sure how large the pool will be, but I think at most it'd be two gallons. I know it's almost impossible to cycle such a small body of water, but I'd at least like to have a filter to help with mechanical filtration in keeping the water clean. However, I know nothing about saltwater filters. Google searches have proved futile, though I once stumbled across one hermit crab owner maintaining a five gallon pool with a small protein skimmer?
What would be the best method of filtering the water? What kind of filters or other appliances could I use?
I don't think that I could use a freshwater filter, and that's all I really have knowledge about. Any suggestions or advice would be much appreciated.
