New Fixture or New Bulbs?
I'm looking to do a mixture of fake plants and live plants in my goldfish tank. I've found some really nice fake stem plants, and I'm planning to have anubias, java fern, amazon sword, and hornwort (floating) as my live plants. I've selected them because they are goldfish-hardy and low-maintenance (unlike most stem plants). I currently have two single tube 18" T8 fixtures with 6500K bulbs that are about 9 months old. Well the hornwort is only doing so-so, and the amazon sword's growth seems to have slowed and some brown algae is growing on its leaves (this is with twice a week Flourish). I thought bulbs were supposed to last 12 months...
If I get a new bulb, will my fixture be enough for what I'm planning? If not, what can I remove to make it so? I like the look and effect of live plants, but without this being a massively planted tank I don't think I can justify the cost of a double tube T8 fixture. If one is really needed here I'll just give up on live plants in this tank.
