Jbl Ferrotabs

[gt568]

They were giving out free samples of JBL ferrotabs at a garden centre I visited today, does anybody have any experience of these? Should they be pushed into the substrate or crushed and poured into the water ect?

I think you add them to new water when you perform a water change.

The instructions read - For the absorption of nutrients through the leaves, 30 tablets for 750 litres.

I'd interpret this by adding one tablet for every 25 litres of new water added. Very similar to the Dennerle E15 tablets I used to use.

You could add them directly to the substrate but unless you have Swords or Crypts then I wouldn't bother.

Hope this helps mate.

Well thats what I thought, I think I borrowed some of those tabs off you actually a while back. However I'm sure I read somewhere on here that they went into the substrate, maybe I imagined it. Should I just crush them up in a pestle and mortar next time I do a water change then?

That's what I'd do.

Are you sure you need the extra iron though? Your CSM+B dosing should provide enough - or are you seeing deficiencies? Or do you just want to see if you get extra growth?

i use them but only under swords in whole tablet form. they are rather insoluble and adding a crushed tablet to your water will result in floaty bits for a week and a massive iron reading (from experience)

the instructions are awefull and i dont really know what you are supposed to do with them. swords seem to like them though.

On second thoughts then.....

I assumed they'd be similar to the Dennerle E15 tablets, these dissolved really well (less than 12 hours) if crushed up into a fine powder using a pestle and mortar.

Hey guys, Any update if these tabs are used by some one, how are the results?
