Review on Seachem 116042604 Betta Basics 250Ml by Donna Maupin

Leaves a white film over the intestines and an iridescent film on the water surface. I've noticed that I don't have to clean the whole system that often because the coating and deposits get in the way. I have a single Betta with a system where water is poured in and it is filtered through stones and ditties are poured through a pipe. I have also not noticed any more plants since using this brand, mineral deposits on cups and jugs I use to soften and replace water. I would recommend another brand
