Hey mike, the site has a note that says no chemicals can be shipped out of the EU. Is this kit falling into that category then?i would say no they are meant for plants arint they. they will have higher nitrate levels and phosphorous than aquarium fertilizers
have a look at this i use these there the cheaper and just as good than stuff like TNC
Thats interesting. I read the technical specs on both the Osmocote and the Miracle Gro spikes and they are pretty close. They have virtually the same ingredients but the values are a little different in a few cases. I have read that you can freeze the spikes then push them into the substrate, which is what I did.A small scattering of osmocote under the substrate is said to be good. I've seen PS3Steveo suggest it's use as a root tab but haven't used it that way myself.
Thanks for that link. I was looking at "aquarium fertilizer" last night and went back today and went ahead and ordered the Root Medic Complete capsules. These should last me a while.I've only had a quick read but to be safe I'd go with no. Osmocote and the like have a slow release system and when you check the temperature charts a 9mnth version will last up to 6 or so at aquarium temps. The M G Spike I just read was 2mnths - even if that is an osmosis style it wont last long in the aquarium.
Where you have to be slightly careful when using normal plant food in the aquarium is with ammonia - We get away with it when using Osmocote etc by using small amounts, burying it and the osmosis tech on the long life versions (reduced for fish tanks)
Get that wrong and you might get in to trouble......
As Dr Rob says - Osmocote (longest life you can get), Ice cube tray - bury it
And check James planted tank for EI chemicals in America, Canada and UK
