I've been reading more and more about using root tabs in conjunction with liquid fert. I currently use Seachem Flourish every 4 days. I do not run co2 or anything special. It's all very low tech.
With that being said, should I use root tabs along with the Flourish? If so, what root tabs would you all recommend? Keep in mind that I have shrimp so I'm trying to limit the amount of cooper that is put into the tank. I know Flourish has it but it has very little in it.
Do both if you can
