another cloudy water victim HELP!

is it odd for a ghost shrimp to eat fish? i "had" a harley with some fin issues but still seemed pretty active. i just got home now and looked into my tank and saw a ghost shrimp eating him tail first! still alive!! wtf? anyways iv been having some trouble with cloudy water (white cloudy) its been going on for about 3 weeks. clears up when i do my weekly 50% water change but it keeps getting more cloudy every day untill my next water change. my params are 0,0,5-10 ph 7.2 its a 55g with 8 corys, 6 neons, 6 glolights, now 5 harlrequin rasboras, 2 SAE's, 3 CRS, 1 RCS, 2 ghost shrimp. i added two more bags of flourite about a week ago but it was cloudy before that. its moderate to heavly planted with two 2L diy co2 bottles. any help would be muchly appreciated.

"EDIT" for filtration i have a AC110 and a AC50.

ammonia 0
nitrites 0
nitrates 5-10
ph 7.2

sorry i just spend most of my time in the planted section. mods feel free to move to the appropriate place.

established for just over a year. but its only been planted since december.

ok my water is still very cloudy and i dont know what else to do? it may be green water when the lights are sitting ontop of the tank it looks more white. but when i shine the lights through the side of the tank it looks more green. it clears up after a water change but then gets cloudyer each day untill i can hardley see through one end to the other end of the tank. i dont use carbon in either of my filters could carbon help clear the water? should i use the blackout technique? how long will my plants live for without any lights? should i cover the tank with a blanket so the room light wont effect it? how long should i leave the lights off for? should i put an airstone in the tank during the blackout? sorry for the all questions but my tank is an eyesore right now and its in my living room. i kinda need some feedback ASAP since my landlord cut my internet off im using my parents. thanks

thanks for the reply BK im pretty bad with plant names but heres a few that i have. java fern, giant red valls, ludwiga, some type of hygro i think and some others that i dont know the names of sorry. they are all pretty easy to grow plants. will they last 4-5 days with no light? should i disconnect my diy co2 for those days? will it screw with things if i lift the blanket up for a few seconds just to check on things? thanks again

what if it isnt green water (sorry im not at home to check my water) what do i do then? man having no internet really sucks!!

ok thanks ill give it a try..cant hurt
