RovingGinger Posted July 30, 2020 Share Posted July 30, 2020 Hi all, I have planted tanks and mostly sponge filters and extra bubblers in most of them. I do not run co2 and I have very hard, high PH (8+) well water. I recently picked up this book: Sunken Gardens: A Step-by-Step Guide to Planting Freshwater Aquariums and it made it sound like you can't have a sponge filter and plants that grow. This is observably false, but now I am questioning the "more bubbles!" approach I've taken (guppies like the bubbles). At the same time I'm pretty sure I've seen minor pearling in some of my tanks (probably from algae but let's not get too picky). What're the balancing factors to keep in mind with this stuff?
