Let's see - you're in/near Mississauga, ON, Canada? I don't know what the Canadian's require to import plant material, but it could be sent as a "gift" to avoid 'some' border scrutiny. Or maybe not... I'd hate to have the Mounties show up at my door.
Generally, within the US, only states with temperate climates have restrictions on shipping aquarium plant material. CA, FL,TX, etc. I don't think you guys in the Great White North qualify as temperate. LMAO...
I assume you're talking Compact Fluorescent's - very bright and pretty pricey... As for the 2x13 CF, were the lamps of a proper spectrum? Is your Fertilization Regime/Traces correct? There are so many variables it would be hard to place a finger on any one component, but
72W of CF sounds like a whole LOT 'o-light on a 10G.FWIW,
