I thought this was discussed once before but I can't find it so maybe it was on the old forum. Can you use these: https://jobescompany.com/product/jobes-houseplant-plant-food-container-spikes/ for aquarium plants? I have some swords and crypts that are starting to look pitiful and was wondering if I could use these to help get them healthy again or what would you recommend instead. I have some organic larger ones that are suppose to be for in the garden but wasn't sure if I could use those either. I don't use Co2, and I know I won't remember to fertilize on a regular basis.
