I have a 29 gallon reef tank that I’m recently having some issues with. The aquarium is around 6 months old. I have two clownfish, two Bangaii cardinal fish, and three trophies snails. All livestock has been in the tank for around 4 months. I’m using an aquaclear 70 HOB filter with filter floss and a 5.5oz bag of chemi pure blue. I change the filter floss every 2-3 days.
I have had diatoms blooms off and on for the past couple of months. About three weeks ago, the diatoms began dying and my rock and sand started to clear up. a couple of days later, I noticed my rock started to turn a brownish green color, as shown in the pictures. Whatever is on the rock is slimy and hard to remove. Around this same time I started seeing protein foam on the surface of the water. I have been doing routine 25% water changes weekly for the life of the tank. Last night, I notice that all 4 of my fish were very lethargic and basically just treading water. I immediate check all levels and everything looked fine. I went ahead and did a 50% water change and hoped for the best. I woke up to the two dead cardinalfish. However, the clownfish seemed to be improving.
I removed the cardinalfish and before I left for work. On my way home I picked up a fresh container of chemi pure blue and installed it in my filter(the current bag was around 2.5 months old). As of now, the clownfish are still somewhat lethargic but seem to be improving through the day. Any ideas what could be going on? My levels are as follows(using API test kit):
Salinity: 1.026
pH: 8.1
Temp: 78
Ammonia: 0
Nitrate: 0
Any help is greatly appreciated!!
