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.
I wouldn’t do it. These fertilizer spike are very high in Phosphorous and Nitrogen. They would seriously destabilize your water chemistry plus you’ll get a serious algae problem.
I use fertilizer spike for my outdoor fish pond, but I don’t know how they would work for an aquarium. I also add Barley to the pond to help control algae, so maybe you can try this as well.
Good luck
no, just go get aquarium fertilizer, a big bottle is under $20. pick up the appropriate test kit while you’re there. If you’re already using it you don’t need to “boost” the substrate, its already boosted. If you’re worried about it, gently change portions of your substrate. Terrestrial plants and aquatic plants draw nutrients slightly differently. A terrestrial fertilizer is not going to sink into your substrate its going to leech into the water and poison your tank. You have a CO2 filter, an established tank, proper fertilizer… are your lights proper for plants and less then 9 months old?
definately not.
buy root tabs specifically made for aquariums. i use these as well as liquid ferts. or upgrade your substrate to flourite or laterite as well?
I wouldn`t risk it you can buy little fertiliser bags for the aquarium from greenline plants i have bought them a few times they look like big tea bags and they last for 3 months their plants are also very good
Yes, look for the Jobe’s spikes specifically for ferns. I have used them for many years with no problems just don’t over do it and make sure you get them deep in the substrate. You can also go find pond plant fertilizer tablets and break them into smaller pieces and use those.
Sure if you want all yuor fish to die , sorry.
