Is you are seeing a light Brown algae the cycle is probably completed So you need to test for nitrate.I had nitrites after 5 days. It’s been 2 weeks and I have no ammonia but plenty of nitrites and a little dusty brown algae. It’s taking longer than I thought. I don’t mind waiting but my wife is a different story.
Waterbox 220.6, marco rock scape with dry sand 78 degrees, skimmer off and socks out...some rubble down in sump as wellwhat is in your tank? what equipment is running? how big is your tank? what temperature is it? have you checked nitrates?
if you have a bunch of rock that is helpful to give the bacteria someplace to live, if there is good flow that helps the bacteria find the ammonia if the temperature is toward 80 degrees as opposed to 75 the bacteria grows faster if the nitrite eating bacteria has outpaced the ammonia eating it is possible to miss the nitrite bump. having said all that, i think it is just building the bacteria colony and noticeable changes will start soon
