guys, wow thanks for the replies, i'l try and answer
i have the swords in both my 180l tanks
for one of the tanks i run presuurised co2 with ei dosing, which i only started 2 weeks ago, at the same time started adding Mg as mt tap water is very low in it, in fact my tap water has gH and kH < 40ppm, typically around 20ppm, pH of 7.2
the other tank will see presurrised co2 this week with 1/3 ei dosing started a week ago and 1/3 dosing of Mg...have been using excel on this tank at double dosing
both tanks have 2x30W + 1 x25W plant bulbs, i.e. 85W over them, guess thats about 1.7 wpg, depending on UK or US gallons used as measurement
i believe the swords were sold to me as bleheri - this link is them (same supplier):
5 Aquarium Plants Common Amazon Sword Plant E.bleheri on eBay, also Live Plants, Fish, Pet Supplies, Home Garden (end time 24-Mar-08 13:55:07 GMT)
i'm really not seeing much growth at all, but more dead leaves than growth, some of the new leaves are a bit 'curly' at first but then seem to straightem up after about 2 inches tall, but maxing out about 4 inches
lights are on for 2 x 5 hour slots per day, co2 on at same time for presurrised co2 tank. this tank has eco-complete substrate about 1" deep, the other (excel dosed tank) has 1" layer of eco-complete with 1" layer of gravel on top.
i think that about answers it all, hopefully???
