Dying plants, any advice?
All my plants are dying, the first wave of plants already died using 2 T8 ultra sun lights. Replaced the lighting with a finnex ray 2 and the second set of plants are dying as well. Wisteria, dwarf baby tears etc.. I added a fugeray planted plus 4 days ago but does not seem to be helping, or maybe it's too soon to tell. The only thing I can think of contributing to this might be the tannins from the driftwood. I added a purigen bag today to aid in clearing the water. I also started using excel about 2 weeks back but to no effect. Does anyone know what I might be doing wrong?
I have a 55g (48x12x21) tank with ADA power sand, ADA new amazonia, bacter 100, clear super, CO2 with a aquatek soleniod (20 lb tank), 48" finnex 2, finnex 48" fugeray planted plus, penguin 350 bio wheel with 2 200 watt aqueon heaters maintaining the temp @ 78 degrees. (newly set up tank)
