Ive had the tank for about 6 months now and I just don't know what to do. salinity levels are about 1.29 and nothing else will even register on the equipment I have. The clown fish are laying at the bottom of the tank barely alive which is surpriseing but I fear they havnt eaten in days since my family member just threw in large shrimp whole. I just need somebody to give me a miricale on how to save them. please help
Short term it's not a major concern. It's off by less than 10%. Just bring it down slowly, over the period of a week will probably do. Just remove a bit of the water each day and replace with RO
. 9 days of replacing 1% of the water volume will drop it to normal 35 ppt levels (sg
= 1.0264). 4-5 days of replacing 2% will get to the same point... I'd be more concerned with what the ammonia, nitrates, nitrites, etc. are at..
