I am a little concerned with my tank. I am a fairly new tank owner (about 9 months and counting) and after a lot of research I've finally managed to maintain our tank, but I've killed several fish in the process. I now have our tank just the way I want it and these fish are very special to me (some I have raised as fry). I have two main concerns:
1 - I somehow manage to kill one of our Red Danios with my last two water changes. I have learned from experience how to clean the gravel without disturbing them to much and have recently learned how to get the water to the correct temp before adding it to the tank. One thing I cannot seem to figure out is how to get the water back into the tank without stressing them out. I have some VERY nosey Mollies and they always seem to go swimming directly under where I am pouring the water. Is there some special way to get the water back in without killing them in the process?
2 - I am concerned with the water conditioner and other stuff being added. I use mostly tap water and I do let it sit for a week at a time prior to adding it to the tank, but on occassion, due to evaporation, I do not have enough water that has sat so I add the water conditioner to it to eliminate the chlorine/chloramine. Recently I had an issue with the nitrates jumping up and after several water changes it didn't go down so I went out and bought some Amonia Clear tablets, which helped immediately. Now I have bubbles at the top of the tank (not collecting, just taking a while to pop) and I am concerned that it is just too much unnatural additives to the water. I do add the aquarium salt with each water change (about 3/4 tbl spoon per 3-4 gallons of new water). So, my question is, what is too much? Or is there even an answer to this question? LOL
Here are my water parameters (if I am reading these test sticks correctly - they are pretty crappy ones):
I hope that makes some sort of sene - ugh! Any advice would help!
