I set up a 12 gallon saltwater tank about 2 months ago. I have fish who are living (yeah!) 3 Damsels and 1 snail. I don't understand much about cycling so I may need some help with this... As far as I can tell all levels in the tank are at normal with the exception of ammonia which is in the stress (mid, not high) zone. I have had a lot of algae but its much better now and also a lot of waste buildup. The waste is definitely much less but there is still some waste stuck to my filter sucker (whatever it is called). I went through 2 filters in 1 week to fix that situation... I'm not sure that my live rock is still Alive as most of it is white. I'm not really sure what the next step is to reduce the ammonia or if its just going to happen naturally... What is the next step other than that? I don't think I can really add more fish bc one of the damsels (medium blue with a black dot on the back) is very aggressive to the two smaller damsels (blue with yellow tail) He doesn't attack them but he herds them. Any thoughts?
