I have a very sparse planting of Halodule (shoal grass) in a 29g under 150w 10,000k HQI. This is my sixth time to try this grass.
Some things I have learned:
80 degrees is a good temperature
MH is the way to go although I have not tried the LED's yet. I did run T5's twice but switched to MH.
Skimmer seems a good idea and works well
Power filter seems a good idea and works well
Some kind of clay in the substrate is necessary. Miracle Mud did not work for me. The guys at Gulf Coast Ecosystems had some thing like Fiji Mud and that is what I am using now. It works better.
Must have nassarius vibex and blue leg hermit crabs for cleanup along with some kind of algae eating snail.
More flow seems to do better than less flow. I am running 2 x MJ1200's
I tried using fertilizer tabs. They are a mess, do not use IMO.
I tried dosing Flourish with some success but I think the products affected my snails and fish adversely. I may try again.
I hope the information helps people and I may actually post my latest on a build thread.
