I’ve used the marine pure balls before, they seemed to work pretty. Been thinking about getting the thick plate this time since I have a sump, and I feel like it would do a good job at bringing nitrates down. But I’ve also heard recently that they leach aluminum into the water. I also watched a Dr. Tim lecture recently, and he made it seem like they are overrated, and bacteria will mainly colonize the outside, and take a very long time to colonize the inside. Been thinking about just running a large fuge for my main source of nutrient export, since it has many upsides and not any downsides that I can think of. Maybe carbon dosing as well, though I dont have any experience with that.
Thoughts?
