“The product (Good):
I have been using Sera Vipagran for quite some time now. It seems to be much better at feeding community fish than older fish flakes; as it both floats and sinks. The granules when propelled by water currents, really excite the fish. I don't have any issue with the granules with my fish feeder.
The product (Bad):
Because the granules sink; they can get stick in grass and rot. Best advice is to avoid over feeding and this is reduced.
The TechDen (Service):
Top notch. These guys have competitive pricing and ship fast. Highly recommend from my experience.”
