Could also give the plants a boost and be nice and lush when its time to add the fishies.
Please let me know your thoughts i would love to hear them as i have a 20 gal tall thats less than 24 hours in to fishless cycle.
If you have plants, enough plants, you don't need to cycle, add the fish and they will provide a CO2 and ammonia boost helping the plants while the plants help the fish.
As far as a solid fertilizer of whatever source, I don't think it's a great idea. They are meant to be rained on not immersed. I might expect that if they dissolve the ammonia "boost" would be, at best, unpredictable, at worst, enough to kill your plants.
Is that the 20 gallon in the profile?
What fish, how many and how large are they?
