Feeding water plants

For those of you who use Jobes tomato spikes to feed your water plants, how many do you use for, say, an 8" pot? I finally found some locally. I found it interesting that the numbers are the exactly the same as for the Jobes water plant spikes (found on line), but are a little cheaper in price.

Thanks,

Banders,

Never have used the Jobes for water plants... I use Highland Rim... but it reccommends 10 grams of spike per gallon of soil per month. Also make sure that you cover the spike over with dirt ... wan to make sure that you feed the plant and not the algae. Hope that helps.
