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.\r\n\r\nIn 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.\r\n\r\nFollowing are my test results:\r\n\r\nSpecific Gravity = 1.020: I realize this is a bit low and have begun raising to 1.024.\r\nPH = 8.2\r\nPhosphate = 0\r\nAmmonia = 0\r\nNitrates = 10: Currently correcting with water changes.\r\nNitrite = 0\r\nKH = 196.9\r\n\r\nAccording to the test kit instructions, the KH range should be in the 100-200 ppm range for marine fish and inverts.\r\n\r\nOther Details:\r\n\r\n1. The total tank volume is 25 gallons with the display tank being 20 gallons. \r\n\r\n2. 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.\r\n\r\n3. I dose the tank with iodine once per week.\r\n\r\n4. Lighting is approximately 4-5 watts per gallon.\r\n\r\nHow 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.\r\n\r\nYour feedback is appreciated.\r\n\r\nThanks in advance.
