I'm religiously following the Almost Guide for my 55 gallon cycle. my ammo is dropping to .5-.25 every 24 hours from 4, nitrites are here there at the upper end of scale and nitrates are around 20ppm do you think it's time for that 50% water change, guide says should be a big spike in both basically unreadable, nitrites are at that point but not nitrates???
