Hubba,

No I have never put soil into my aquarium.

Carlos,

One would expect a product like that to be atleast a somewhat decent supply of Iron. All tanks I never doesd have been 100% Flourite, 3"+. I wonder if Flourite is that Iron rich...

dennis

I thought that the benefit to Flourite was the high CEC allowing Fe adn other nutrients to be available to plant roots, not necessarily the amount of Fe it actually contains. That is true for peat too though right or am I mistaken?

if you'll notice, flourite's cec is 1.7...rather low compared to others...

dennis

Its also rather low in Fe too. One of the lowest. I wonder about peat moss and Eco complete. Where are they in respect to that list?

ShaneSmith

Flourite does not seem to be that helpful with Iron. If i had a choice i would use Onyx or Eco-complete for my 50gallon.

Sorry for being off topic but i dont want to start a new thread over this, Would Lignite be like adding activated charcoal to a substrate?

hubbahubbahehe

lignite, activated charcoal? do you mean they are the same? you mean diamond black right?

ShaneSmith

Carlos says Fertiplant plus has lignite in it. I looked it up on google and its a source of power like charcoal. So i am guessing its similar to charcoal in a tank. Is black diamond a form of charcoal used in Substrates???

dennis

Black diamond is a brand of activated carbon for use in filters. I assume, but do not know, that that they could be used that same. I know that charcoal and carbon can be bought at my local garden center to add to the you potting mix. Would it the be a source of DOC? (dissolved organic carbon) Would peat also have a high DOC?

hubbahubbahehe

i know soil has a lot of DOC cuz Ms. Walstad mentions it in her book
