For some reason, this forum has focused on fish and the behind the scenes of our finned friends........but I have a group question about the hobby and reef additives..........I contend that the main reason the majority of hobbyists fail to do well and in turn drop out of the hobby......is all these reef potions and the green fur that results...when adding them ......I maintain eight reef systems in our store and add very little if anything to them ... other then water changes every two weeks ..............I have never had Hair algae in any of them ...I use the same RO water... the same salt ....the same live rock....We even use more light .....1000 wat and dual 400 watt bulbs!.........yet the majority of our customers have never ending battles with the green stuff.....We sell a lot of supliments and DTs .....Does the marketing of all these supplements actually HARM the industry by causing many to fail .......and thus exit the hobby.......?
