So first off, I'm new here this is my first post, but from browsing around already I will definatley be posting and reading here alot. I hate to just jump right to the problem but I must...
So I have a 30Gal tank, I've had it up and running for roughly 4 months - everything has been fine.
I recently purchased some new tank ornaments (one fake plant was also added), I let them soak in water as normal. I then added them to the tank.
Now a little while after adding them, roughly a day... I noticed the tank was starting to get cloudy, so I did the normal water test for ammonia, nitrate level, ph and that.
The nitrate level came back High, so did the ammonia level. so I then preceded to do a 20% water change - yes I did condition the water.
I left that water sit. The next day I went and purchased a new Canister Filter (Fluval 305).
I then again did a water test, and the levels were still very high so from reading I basically came to the conclusion that another water change would be needed, possibly a 50% one... so Idid that, I did a 50% water change.
Then yesterday I tested the water, and STILL the ammonia is reading high.. at this point, my angel fish were showing signs of poisoning. I did yet another 20% change (as I was told this may need to be done every other day or so). SO here I stand now.. the ammonia is still high, and I lost 2 angel fish and 2 red eye tetra's. I am stuck at what I can do... I added an ammonia pad to my filter to try and reduce some of the levels, but it does not seem to be helping. Please help if you can... I appreciate it.
