Found these at the dollar store the other day.
Anyone ever use these in their aquarium?
I was going to cut them and stick them under my crypts and swords for extra fertilizer, but thought I'd check to see if this has been attempted.

I have actually done this once. I had them and I figured that they will work. However, these are not designed for aquatic plants. I broke one up into four pieces and put them in a 20gal tank. They made the nitrates spike quite high. I battled algae for quite a while. Admittedly though, the tank didn't really need fertilizer like this. I had a rich soil substrate.

Stay away from those things, they damage the plants in our conditions.

jw, Is this a conclusion from experience? Or word of mouth?

 

[deicide]

Experience. Don't be fooled by my low post count I have a fair amount of experience

Don't they have phosphates in them? If they do then you really dont want to use them. Just my two cents.

Too HIGH in phosphates. Use them if you want or need algae.
