| Well i thought I'd update this . We have 1pony and 2 adults now. The pony is 35 days old. The male I thought it was preg but when we tranfered him to the other tank he was nolonger preg. Not sure what happened. Any way he don't look preg now. We haven't lost any more for 5 days now.So maybe things are ok now. i'm starting a new filter up in the 5gal. tank while they are in the 2 1\2gal. I change 2gal. of water aday to keep everything in order. They seem to be eating good . I need to figure away to get the older brine out of the tank with as little disturbing action to the horses as possible.Right now I sifon it out with a airline, about a gal. and then gravity flow back in with a airline. They don't seem to get to stressed out that way. |
