Mine do sometimes after a water change...but it usually clears within a couple of hours or so.
Cleaning filters:
-every 2 weeks change the filter that has the carbon in it
-once a month (occasionally a week or 2 more) I take them apart & give them a good cleaning while doing the monthly maintenance the bio
filter(s) sit in the last bucket of water I removed from the tank
Water changes:
-water changes: usually weekly (although on occasion is has been longer, but that is rare) 29 gallon tanks - 27 liters; 10 gallon, 9 liters (I'm lousy at metric, I know the liters by the markings on the bucket :-? :oops: )
Yep, use a gravel vac
Oh my gosh, I just tested my tanks...the ammonia in the goldies tank was 1. I have had my tanks over 2 years now & it is the first time this has happened. I immediately did a 50% water change. Any ideas as to why this could have happened????? Nothing new in the tank other than a couple of artificial plants, they hadn't been used in quite awhile but I rinsed them really well.
So, what makes an established tank's ammonia to go up????
