Lightbulb DYNAMITE premium use as root tabs

So far I have been using root taps as fertilizer for Amazon swords with great success.

I am wondering now is there anyone here who has experience with Dynamite 13-13-13 premium plant food to fertilize plants in a fish tank instead of using root tabs?

Hi g4search,

Based upon the MSDS the product is similar to Osmocote in that it is encapsulated fertilizer. It does have substantially greater phosphorus / phosphate than Osmocote and I would be worried about a greater likelihood for algae blooms. Both products use ammonia as the nitrogen source so buried deep in the substrate is a must.

So, I've used dynamite in land-gardening before, and osmocote in both aquariums and land-gardening.

My only concern with the dynamite is that it is a very slow release fertilizer, delivering over 9 months in soil, while Osmocote releases in 4 months. So at the very least, you will probably need to adjust dosing to deal with the longer, slower release.

I'd also suggest favoring their all purpose 18-6-8 formulation, rather than the flower and vegetable garden 13-13-13 version. Aquarium plants are mostly leaf mater, and need a bit less P and K than plants that are blooming heavily or producing fruit.

To both Roy and Matt,

Thank you so much for your replies here.

I appreciate it. (I am actually really ticked off, because I wrote a long reply discussing various issues. That took several hrs. Apparently, I have been logged off during that time, and I now lost ALL my typing.

You are welcome...

Sorry to hear about the submit issue...

One additional thought.. I'm not sure what breaks down the resin coating in dynamite... it is possible it is dependent on bacterial actions from bacteria common in soil, but not so much in aquatics...

If that is the case, the dynamite might not properly release...

That said, I think it will, but there's a possibility it won't..

I have some Dynamite in some tanks, but have not been monitoring the parameters (no fish in those tanks). Plants and algae are growing well.
