....I use water conditioner for the water I put back in during w/c's and I also use a algae destroyer once a week. I dont use this in my 55g....could this potentially be my problem?
I avoid putting any chemicals in my tank at all costs besides dechlorinator.
Heres the few questions everyone has been getting at.
After 7 months, nitrATes are at 0.... that surely points out to everyone that your cycle isnt completed yet.
Brief recap. Amonia ->nitrIte -> nitrAte. Often times you dont have nitrAtes because you don't have the correct bacteria to convert from the nitrites to the nitrates.
Now to the algae fix chemical you're using. What type of algae are you getting? If it's to try and fix green or cloudy water(bacterial) then that's another sign that your phosfates are too high or your beneficial bacterial is not established to control the clouding effect.
Depending on the chemical, it can be harmful to the beneficial bacteria in the filters. You could be nuking that bacteria every time you treat your algae problem. If it's the type of chemical that "clears" your water, it's bonding the algae/other debris which will make then larger so that your filter can collect them. thus plugging up your filter/choking out the oxygen which can kill off the bene bacteria, restarting your cycling process.
Next, we have another element to the cycling process. If i cycle a tank, with 1 goldfish. That tank has enough beneficial bacteria to process the waste of 1 goldfish. Now I test the waters and see that my tank is cycled, awesome!
I add in 5 large Pbass, a pleco, cats, etc. The night goes by, and I have enough bene bacteria to process 1 goldfish worth of waste. The rest of the waste is trapped in amonia or nitrite. the bacteria to process from amonia to nitrite establishes pretty quick, but it takes a while to go from nitrites to nitrates.
So you probably lose a fish, and see no nitrates, or amonia, skipping over nitrites. So you do a water change, cause that can't hurt. Lowering the amonia/nitrites in the water. Basically you put a bandaid on the problem. The next day or two, you have more die off, the shock from high amonia/nitrite levels.
Any one of these could be the cause of your problems. Getting into a rush, and trying to "QUICK FIX" the problem is what is causing your problems. You have to build an aquarium 1 fish at at time. It's just like if you baked 1 cookie, and put yourself on the market and got an order for 10,000 cookies you'd be overwhemled and not ready to accomplish that, and you crash. Same thing happens to your aquarium, when you don't build it one step at a time.
