Update

The arowana is growing nicely but seems to have developed a protruding lower jaw. Was told by Gan of Gan Aquarium that a shrimp diet will cause this due to the calcium in their shells. I am not feeding shrimp, but I was dosing Seachem Equilibrium for Calcium and Magnesium for a while for the plants. That might have been the cause in this case. I've stopped that, so I hope the condition will resolve itself.
The plants are growing nicely although the tank suffered an algae bloom a few weeks ago. CO2 injection rate had dropped and I hadn't noticed despite having a drop checker in tank. BGA, Hair Algae and Brown Algae all struck at the same time. Adusted CO2 back up and started a anti-biotic (Erythromycin) course on the tank. Brown algae stopped spreading, BGA died and Hair Algae slowed down.
However, the Hair Algae was still growing back too fast. I stopped Nitrates and Phosphate dosing, started on Potassium dosing since I've stopped Seachem Equilibrium and dropped lights down to 2 rows of T5HO throughout the lighting period. Plants are still growing happily, the Hair Algae is much slower now.

Bolbitis heudelotii - Part 2

In my previous post, I wrote about my hopes for this plant in my tank. It has not disappointed and grown back lushly. Now I'm wondering where to reposition it in the future for best effect. Perhaps I should tie some on the exposed wood over the open sand areas.
