Gardening Methods

can I use the kind of fertilizer spikes used in garden pots in an aquariumwith plants and fish?

i am planting out a 110 gallon soft water aquarium that has been established for 8 years or so and the substarte is exhausted. i have co2 injection and feed liquid ferts. But i would like to boost the substrate and was wondering if the king ofpsikes found in garden centers for potted plants would do the job?

They will kill your fish and fast. They are made of ammonium nitrate and phosphorus.
