I recently switched from a single t8 tube light fixture to a dual t5ho fixture. I started dosing with flourish comprehensive the day after. I also saw some flourish excel on sale, so I bought it but haven't used it yet. About a week later, I have an outbreak of bba. It's not too bad, it's mostly on the driftwood, but there is a little on the leaves of my plants. I was hoping that the cabomba and water sprite I bought would grow fast enough to outcompete the algae, but I guess it wasn't enough. I've reduced the feeding and the photoperiod to about 8 hours. Does anybody else know of anything else to do? I know siamese algae eaters will help, but I can't get them locally, and I'd rather not have to add them if they're unnecessary.
