Hello! In a previous thread I had asked about the reduction of nitrates in my tank. I had since followed the advice and removed the bioballs and converted it into a DIY media basket/refugium using egg crate (two shelves; the first holds several media bags, being chemipure elite, purigen, and a de-phosphate media by Seachem and the second shelve holding chaeto with a fuge light). Above it is my biocube cartridge, as well as some filter padding to catch excess debris. I dosed Microbacter Complete Bioculture daily for two weeks and used Prime by Seachem whenever levels got too high or doing a major water change. Speaking of them, I did water changes rather frequently. I added more dry rock on top of my live, bringing my total around 15#.
Now here is the question. I performed my filter mod (removal of bioballs and installing DIY media basket with media and chaeto) yesterday, and I have not seen a reduction in nitrates since then of 20 ppm
(they were that high prior). How long will it take for them to go down, and by how much so should they?
