I have been having problems with elevated nitrate levels (20 ppm) and wanted to reduce them... I had done a number of 10 percent water changes on the 32 gallon hex with little effect (not significantly noticable on the color chart). On Saturday morning I thought I had lost my new Flasher wrasse that I had put in the previous day, so I said what the heck and started a big water change. I drained 9 gallons out of the 32 gallon hex and moved some rockwork around (not sure how much water my 28 pounds of rock and 40 pounds of substrate displaces) which probably equates to a 40-45% water change.
After the change I tested the water again and by golly the nitrates did drop in half and oops! the ammonia jumped to .50! I ran to the store and got some prime and double dosed the tank and everything is fine. Checked the ammonia levels last night and they are back to normal.
Anyone know why ammonia jumped so quickly and dropped so quickly again?
