I added a Bubble Tip Anomie to my 3 1/2 year old aquarium two weeks ago. During the first 10 days, it seemed perfectly happy; it hosted one of my tomato clowns, had a healthy appetite and settled in nicely in a spot on the reef. In the last 4 or 5 days, I notice that while it responds to light and other stimuli, the tentacles have "deflated" leaving it to look like a big white disc, still firmly attached to the reef. Following are my test results: Specific Gravity = 1.020: I realize this is a bit low and have begun raising to 1.024. PH = 8.2 Phosphate = 0 Ammonia = 0 Nitrates = 10: Currently correcting with water changes. Nitrite = 0 KH = 196.9 According to the test kit instructions, the KH range should be in the 100-200 ppm range for marine fish and inverts. Other Details: 1. The total tank volume is 25 gallons with the display tank being 20 gallons. 2. I do a 20% water change weekly. I prepare the water using a 5 stage RODI filter. The water is continually moving via submersible pump with salt mix and buffer added. 3. I dose the tank with iodine once per week. 4. Lighting is approximately 4-5 watts per gallon. How do my numbers look? Is there something else I should be testing for? I'm feeling a good amount of frustration; this is the second time I'm trying with a BTA and I'd like to enjoy success with it. Your feedback is appreciated. Thanks in advance.
