Having problems cycling with instant ocean bio spira

[leo12345]

I’m new to saltwater fish tanks and I’ve been trying to do a fishless cycle on my tank for about 2 weeks now and I dosed with instant ocean bio spira (which was supposed to cycle instantly) and dr Tim’s ammonia in a 29 gallon, my nitrites ph and spiked for a while but are ok now but my ammonia is at .5ppm and my nitrates have been at 10 ppm for 2 weeks now and it won’t go down. I’ve added more bio spira and did a 25% water change but nothing seems to work, do I have to add more chemicals or something, or is this normal and I just need to just let it do it’s thing. Any advice would be great. I’ve also been using a api master test kit to test the parameters.
