Ya know, call me stupid, but I think you've hit the nail on the head.
After my first foray with these plant fert bombs, I had an immediate
explosion of green water. I won that battle. Now, shortly after
placing these bombs again, shazzam! algae infestation of epic
proportions. I did check the ingredients, and thought they were safe.
Mostly the trace elements, with very low nitrogen or phosphorous. I'll
look again and see if they actually identify urea or NO4. If I leave
them covered up and undisturbed I think (hope) the plants will eat
them.

What brand are your fertilizer pellets, so I know what to avoid? I just
added Aquarium Pharmaceuticals Root Tabs plus Iron laterite pellets to
my tank a week or so ago and so far so good.

TIA!
