Review on Good News Aquarium Generator Diffuser by Rosa Gomez

They are good quality but I bought them for use in an Artemia hatchery and I use regular water bottles as they are more convenient for my needs and I carry them with me technical features that set them apart from the competition, as they are suitable for normal water bottles. Only water bottles of 1 liter and larger will fit, and possibly a smart water bottle or other large neck bottles. A normal water bottle from a suitcase is too big. 3 stars for the quality but I'm about to return it.
