How do you make DIY Root Fertilizer Tabs for Planted Aquariums?
You can make DIY Root Retlilizer Tabs for planted aquariums with just balls of Osmocote Plus fertilizer, and regular gel caps purchasable from Amazon's health and wellness section. Just open the tabs, fill with the Osmocote and close the tabs again. Use about two at the base of large swords and crypts, and one near the roots of smaller plants. Careful to shove them deep enough that they won't pop back up. Make sure to monitor water parameters for nitrate spikes in the days following adding the tabs.
