Antique Chinese Porcelain Fish Bowl Planter on Wooden Stand

This is a very large and very heavy Asian decorated fish bowl planter. It is 18" tall and 20.5" across rim to rim. It is floral and colorfully decorated with pastel pinks, purple, orange, blue, Green, and yellow on the outside and top rim. There is a goldfish and floral scene on the inside. It is stamped with a makers mark that contains six red Chinese characters inside a red box with no corners which I believe indicates it's from the Qing dynasty Jiaqing period. I'm not for sure on that however. It's in excellent condition. The wooden stand is 8" tall and 11" across. I'm wanting to find out the true identity of the maker, the age, and also the worth. Thanks!
