Hey guys just looking for a little help here, so heres my problem. I have a 55 gallon tank that has been operational and happy for just over a year, with 19 chiclids, average size is 3 inch (variuos types....but i dont think the species will make a difference, if you think it will i can make a list) It seems as of late, allot of algae (the hard green type) grows rapidly on the glass of aquarium. I have been doing 25% water changes weekly, aswell as using a razor blade to clean the algae (almost 2x a week). In my filter (fluval 404) i have used, and currently am using the filter media used to controll algae, (green x is what it used to be called). I do have a moon light set up in it, which is basically just a string of 10 or so blue LED's. i have it turned on, on the lowest setting everynight, and the lights are on from 7AM until 5PM. so i was just wondering if the tank is overpopulated? or maybe just a little to much light, the tank does never see direct sunlight. any replies would be muchly aprreciated!! THANKS!!
