Hi,
I set up a 3-feet tank recently, and using Seachem liquid fertilizers. They are a bit costly.
Is it possible to buy dry fertilizers for planted aquarium in Singapore?
I didn't notice them at LFS, even at big ones like Seaview and Qianhu.
Can anyone tell me where to get them?

Advice from boss Felix
unfortunately you wont be able to get KNO3, you might want to substitute it with CaNO3
Is there any disadvantage if we dump ca from cano3 to the tank?
It is fine as long as you do weekly water change. It wont accumulate until become toxic
I see,
I believe it might increase your GH water, once you add Ca over CaNo3.
