I have a 50 gallon tank with a Fluval 304 and 2x40 watt globes that has been up and running for about 4 months now and about 3 months ago long dark green hairy algae started to grow. I have had 1 bristle nose cat fish since the start and just recently have bought 6 Ramshorn snails and 1 chinses algae eater. I have also been using algae killing tablets and liguid but his does not seem to be doing anything. I have also cut down on the amount of food that I am feeding to the fish. Please help me as this algae is very ugly and is slowly killing my plants. I have tried manual removal but it attatches it self too hard and it kills the plants. It attaches it self to everything ???
