Welcome to the area haha, we're in farmland and you'll just have to deal with the nitrates. Prime will take care of the chloramine until your bio clears the ammonia. The LFSs around are almost all geared for Africans and salt. CA are not very common. SA are somewhat easy to get if they're common. It's quite hard to keep SA healthy in our crappy water. Would require RO to keep any of the less resilient SAs.
Oh hi wasn't expecting many if any people from Omaha on here but glad there's at least one. Pardon my ignorance but what is CA and SA?
What do you have?
