Depth of ADA Ammazonia for DHG and HC Cuba

Hi all,

quick question.

In my 60l I have a thin (2mm) layer of sand on the base covered by around 1 - 1.5 cm of ADA ammazonia II.

Is this thick enough for Dwarf HAir Grass and HC Cuba root systems or should I try and build up the depth?

I have more available from another tank, i just didn't go too deep to begin with due to the change in PH for the shrimp that were living in the tank to begin with. However I dont want to go adding more if i dont have to as the extra nutrients may encourage algae growth.

Pellet sizes of the sub are quite large (coco pop sized).

Hey, I've grown hair grass and HC in 2cm deep soil before. As long as your water column is well fertilized and CO2 rich HC seems to be able to creep onto stones and wood as well. 1 cm seems really thin for a substrate though.

Large pellet size doesn't seem to affect HC growth but you might find it difficult to plant in. Also for hair grass, you can add substrate onto the planted hair grass field if you think you need more substrate, it'll just grow out.

Thanks for your advice.

I raised the substrate up to around 2-3 cm and everything appears to be establishing well.

I'm getting pearling on the hc anyway, so i can only assume that's good.

I'm dosing about 2 bbs of co2 while the lamp is on (about 10 hours) and everything seems nice and green.

I'm a little concerned about lack of water movement and the co2 being all in the same place, but that's for another thread
