So, what does everyone use for fertilizer in an emersed tank?

I'm going to use miracle grow potting soil, but those nutrients won't last forever!

I'm looking for something to put down as a base layer of nutrients under the soil as well as something like a weekly fertilizer.

Osmocote Plus should be used in small amounts - definitely don't add a layer. It'll break up far too quickly. You could add a few granules or a gelcap near your rooted plants, though.

If you're mixing dry ferts with water, just divide the standard EI dosing amounts by however much you need to fill your spray container. You won't have to get things 100% but you'll get pretty close. Since you won't have critters in the tank, a little extra probably won't hurt much.

def get an organic version. and should work great!!!

if u are going to put livestock in it.. give it 3 weeks to remove ammonia.. it leached very fast in my tank... i had lots of floating plants that controlled it very well during the process.. i did a 50% wc and dumped in my shrimp.. they are still doing great

note.. i used seeded filter media to start the process


edit: dirt has a high CEC which means it can exchange and hold nutrients very well. one of the reasons why dirt is the foundation of most horticulture.. nature uses it for a reason :)

Thanks, HD! I think that is what I will do. I have access to lots o' different fertilizers for a good price..

This will be an emersed tank, so it won't have any water. Which means no livestock. Pretty much just a plant holding/ farm tank.

Dirt. Just add a top layer occassionally and nothing else. Works well. I have thought about adding aquarium water when I top off the water, though.
Thanks, Sara! I've been misting my little containers with tank water, and it seems to be working well. I never thought about just adding new dirt....

If you take 1/2 to 1/4 EI -- Which is basically your water change water! -- you can dose an emerged tank happily. I like to spray with DI water only to keep humidity. If you use tank water it leaves spots on the leaves, and that may annoy you.

Humidity is many times more important than exact values of ferts in an emersed set up. This is because you know you have plenty of CO2 and just need to male sure nothing starves. The same thing is true of a CO2 injected aquarium.

Emergent is really easy after you tackle the humidity/hood. I type this again because the real trick to emergent growth is to stay patient and just let the plants convert an do their thing.
