I have no idea how to setup layers of substrate with mixture of different fert.My tank will consists mostly small to medium plants.Any tips and guidelines for a good setup??
Anyone tried using fert sourced from nursery or other cost effective alternative??
Really appreciate your comments and many thanks in advance.

Hi there,
Am new to this forum...thought I can contribute.
You should have about 1cm of base fert in place...there's no hard and fast rule of how much you need to put in so I'm just estimating. Normally the base fert should last you about 2 yrs with the occasional supplement of gravel ferts. You would need a minimum of 3" of gravel as certain plants' root system requires a deep gravel to hold. Your gravel size may still be too large. Try getting 1mm size ones.
All you need to do is lay the gravel on top of the base fert..that's all.
Certain fert from the nurseries may not be suitable for aquarium use due to the difference in the composition of the nutrients. Who knows what other chemical are added. Stick to those by aquatic manufacturers. Of course different brands come with different quality and pricing.
I hope this answers your questions.
