Here's a good gold-grinding tip for pros, at least level 100 Ascended. Every time you do the daily "Nothing to See" quest, grind Trogolodyte Mages with the remaining time your seaweed has left. Don't sell until your seaweed ends. If your inventory is full, the next time you get loot, replace a rusty cannonball with kelp, Underwater Staff, or an Ocean Ring. Try this the next time you do this daily.
