Is there anything in your system that is not from natural salt water, have you added any rocks, slate, etc, not reef, but rocks, lava rocks, or anything else that is not marine in origin. also are you adding anything to the system in the form of additives?. your pH should not be that high with a salinity at 1.021. I still suspect something is amist with your water parameters. try to get your temperature down to 78 with a max. of 80 in 24 hours. any aresol sprays used in the house i.e. air cleaners, sented candles, dusting spray, windex on the aquarium, carpet ceaner, etc will contaminate the system. is all of your equipment, water barrels, buckets, and equipment cleaned and steril used for no other purpose?. The problem with anemones is that if they sting the fish the fish will die. are the bubble tips stationary or moving around. This is a process of elemination. I doubt I can determine the problem from here, but you surly can by elimiating each possible cause. Hopefully something ive posted will help. When do you add fish and when do you do water changes.
In order for me to help any further you will need to take water tests in the morning 1st thing just before lights on and at night just before lights out for:
Ammonia, nitrite, nitrate, co2, oxygen, calcium, pH, dkh, magnesium, copper,
temperature. provide a list of everything you put into the system, food, additives, when and amounts, specifically provide a specific list of how you provide makeup fresh water and how adminstered to the system, and how you prepare your fresh salt water for water changes, list all equipment, and procedures and provide a list of all equipment that is running in your system, what is near the tank, above the tank, next to the tank, and what is the traffic like infront of tank, tapping on glass, loud noises, etc. once you can provide all this I may have an idea or two. good luck and hope something here helps you investigate what is going on. i would recommend you only add one clown fish to your system and nothing else unless you can keep um alive for three months. do you have anything in the system that can sting the fish, tube worm, anemone yes, or anything else. Are the fish rushing and hiting the tank walls, jumping or acting strange when you put them in. do you have a cat, does cat get on top of tank. i had one years ago that would let its paw dangle into the tank and hood 1st fish came by, i had all angles in the fo system. anyway look for the obvious and the not so obvious. sit back and ponder what is going on and try to perform the basics to illiminate things down. good luck.
oh and one last thought, check out the pH of the lfs and set yours to the same level or not more than a point off. pH should be 8.2 max and hover between 8.1 to 8.2. also when you add fish you need to turn off the lights except to the atinics or subdue the lights until the next day to give the fish a chance to settle in. are there any pumps, that could suck the fish or any heaters unshielded in the sytem. boy. if all of the stuff i mentioned is good then you must have something leaching out into the system.
