Ok... this is the exact light I got. Hagen Power Glo. ALL I can find in 18" at Petsmart/co are 15W. But... this one is for coral, invertebrates, and plants so hopefully it should help. It says on the box that it is 18,000K. Is this better??????? It doesn't have a purple look to it. It looks more blueish than the old bulb. Aquatic products
Petsmart didn't have a very big selection. I went there first... I got 2 4" plant tubes there, Umbrella (Spathiphyllum wallisii) & Gold Ribbon (Dracaena varegatus) If the Gold Ribbon dies oh well. Same family as the pineapple plant.
Petco had them on sale buy 2 get 1 free, so I got 2 4" tubes - Argentine Sword (Echinodorus argentinensis), & Kyoto grass (Ophiopogon japonica), & 1 large potted plant from the aquarium, Bleheri (Echinodorus paniculatus)
I happened to see several plants like my pineapple plant in the tank there at Petco. And yes they are of the Dracaena family. Heh!!
So anyways... I am going to order a few more online probably Tuesday. I found hardly ANY selection. All the Amazon swords I found did NOT look healthy. At both places. When I order online I'll definitely get more of the varieties that you all have suggested to me.
I will take some pics of the new plants shortly!
