Removed biowheels now nitrates high

Hey everyone i need some help on my nitrates. I received some advice from someone on the forum who told me to ditch the wheels in my biowheels. Did as advised and noticed my nitrates shot up quickly after doing that. Went from barely detectable to somewhere between 30 and 50 (test with low range red sea nitrates kit). I have since added a product recommended by my lfs that has tiny bits of carbon and something else that helps with nitrates that comes in a media bag and is good for 4 months. It wasn't helping with nitrates the first week of using it. Then i purchased denitrate, changed filter pads, put chaeto into the biowheel canisters and have light on the chaeto during the day about 14 hours (need smaller less bright lights so i can run them at night and not bother the fish). I have also noticed either detritus or something else floating in my water which I'm sure i kicked up while vacuuming the sand (should mention system is 2 years old and former owner didn't vacuum). So the crap in the water is my fault I'm sure. But could the biowheels being removed have caused such a change as to affect my nitrates like that? One person who seems very knowledgeable says yes. Just wishing i had left them in now even though most say ditch them. Seems like trying to prevent nitrates caused them in my case. So now that my water quality went to crap how do i deal with this. Changing around 25% water a week seems to do nothing for me. Should i get a filter sock and use my little circulating pump i mix water with to pump water through the sock and clean up my water? Maybe it's detritus causing nitrates? Any advise would be extremely helpful. No refugium hence the chaeto in the biowheel canister and I am running a little hob protein skimmer. Please help before my corals get too unhappy. Thanks in advance to everyone. Forgot to mention there is about 70 lbs live rock in my 55 gal
