Wow.. i did my weekly water test today and my nitrates were at 40!!! Usually they are around 10 and never more than 20. I always do a weekly water change of about 30%.. sometimes more if i feel its necessary. And i test my water weekly ... usually before the water change and only afterwards if i had a problem. Like today i will check it afterwards to see if the nitrate has gone down.. lol. But any clue as to the sudden spike? The only thing ive added recently was 3 guppies and an angelfish.. not much of a bioload... I guess i can cut down on feeding but im usually pretty stingy with that too.
