What does this think contains? Is it for a new planted aquarium or can it also be added in an already established aquarium in the substrate for root fertilization?
Can I also add some of this product and how will this help?
This product is great for starting off or "regenerating" the substrate. It has a very high CEC(ability to hold nutrients, thus making it easier for the plants to get the nutrients), it has good number of macros(N:1 K:25), but no phosphate, and it's loaded with trace elements.
You can add it later on by pushing a few sticks at a time into the substrate. It will help your substrate considerabley by providing it with what I mentioned above, because as you know Sera Floredepot(is that what you're using?) only lasts for 4-6weeks and is only made to start off your substrate, not supply nutrients continously..the same goes with any substrate additive.
I also recommend you dose through the water column to insure your plants get enough nutrients. Don't rely on your substrate(you never know how many nutrients are left)..use it as a back-up only!
