No, the Osmocote is mainly for enriching the substrate, mainly for the benefit of the root feeders, most aquatic plants take in some or all of their nutrients via the water column.

My plain gravel (around 1-2 mm in diameter) couldn't hold it from leaching.
But no algae problem apart from a few days of GDA on glass.
jasonwantyou;72843 said:Osmocote plus doesn't contain PO4? is your PO4 DIY?
nipat;72851 said:Osmocote Plus here contains PO4 (it's 16-8-12).
Are you still interested?
Before using Osmocote Plus I had been dosing PO4 via EI method using KH2PO4.
Then after using it, PO4 climbed to the level I didn't like, so I stopped KH2PO4,
but continued dosing others (KNO3, Trace Elements, etc.).
nipat;72896 said:I'm not sure, but it's probably different from the ones you see in US market.
But the ratio is close (16-8-12 vs 15-9-12).
There are different formulas of Osmocote Plus sold in different regions.
