API Root Tabs Freshwater Aquarium Plant Fertilizer
I tried these for the first time today and found that they dissolved within 5 seconds. I didn't get them buried before they completely disintegrated. I churned up the laterite where they dissolved in the hope that they will work. Put them in with tweezers as fast as you can! I was dropping them on to the bottom and pushing them in with a rod, at least that was the plan.
