hey guys im new to this site. i have 55 gal reef, bout 60 ibs of lve rock. 2-3 inch live sand bed. ive had the aquarium up for about a year and had the bta for about 5 mos. about a week ago it started looking really bad. all shrivelled up and stringy. it has not gotten any better. i think i might know what the prob is but im not sure. i had some bad ammonia test strips and just found out that my ammonia is .25. i did a water change on weds. and another today. i also added a poly filter as the pre filter to over flow. is this most likely the problem and whats should i do? is there any chance in this guy making it? its bee about 8-9 days all shrivelled up. it seems like he ate the silversides that i gave it( had to kind of hold it on its mouth). nitrite is 0 and nitrate is about 5. why did he ammonia go up and not the others? its foot is still holding on real wellso im not sure. i feel bad for my clows cause they are kind of homeless now. i fanyone can help id really appreciate it
