i just check my ammonia in my tank and its at 0.5
my tank has been going for nearly 2 years now

i havent done anything different like change in feeding or anything.

So what causes ammonia spikes??
 
Hi,

small ammonia spikes can either be due to 4 reasons:

1) overfeeding (which wouldn't really be a problem if you cleaned enough to compensate for it)

2) too much waste (too big of a bioload for the size tank (maybe your fish have gotten bigger ??)

3) A "die off" of beneficial bacteria somehow or another. Possibilities could be that you changed too much filter media at once or that you just medicated and it "may" have killed off some of the good bacteria or you've thrown away quite a bit of gravel??

4) You have stopped cleaning as much as you should (ie-the water changes once a week and the vacuuming once a week)

Anything sound familiar ? :/
 
an angel did have finrot which i medicated last week (unfortunatly he died)
could that have been the problem you think??
but i did a 20% when he died on monday.

Do you think it still could have caused it??
 
Well.......if there is NO other apparent reason then I would say, Yes it very well could have caused it :nod: ESPECIALLY depending on WHAT you medicated with. I recently had a VERY bad experience with PimaFix KILLING 2 of my Silver Dollars. :-(

melafix is fine.
I'd never used pimafix before though
 
Interesting thing..........peel the label off your Pimafix bottle and read the back of it....all the way at the bottom................. :(

I'll see if I can find my thread........
