Well, about 6 weeks ago I switched to live plants, got an RO water filter, and started DIY c02 injection. My water since I got the RO unit has never been more perfect. My nitrates and nitrites are zero, my PH is perfect, hardness is ideal, water is just better than I have ever had. I have 4 watts per gallon of light, put in Flourish tabs, and with the c02 injection my plants are growing like wild and pearling good. But now all of a sudden in three days I have had 5 fish die. They do not have a mark on them, no apparent disease, and there has been no fighting in the tank. Why are my fish dying? I have a canister filter that is rated for a tank larger than mine, and like I said, my water tests perfect. Can anyone give me some ideas? The fish are dying quick since I never saw any one of them swimming funny or acting funny. I just don't get it.
Fish dying for no apparent reason, what gives?

What time of the day do you find them dead?
In the morning?
Maybe at night, when the plants are using oxygen too, the O2 drops too low and causes suffocation.
That's my best guess.

OK guys you may be on to something, fish are found dead in morning everytime I think, not certain but I never see them act funny and find them dead early in day when I look at tank. If this is the case (and is it?) should I just turn my c02 off at night? But if this is the cause why didn't it happen early? I have had c02 going the same amount for about 4 weeks, fish just started dying 3 days ago
Bach,
What are the pH and KH in your tank?
(I think it's important to diagnose these sorts of things with as much science as possible. Calculating your CO2 concentration would be best to determine if what everyone is purposing is actually what is happening. Otherwise, this could just be grabbing at straws.)

hmm... what fish do you have in there? i saw 2 gouramis, and was it some rasboras?
have you had any gouramis die? they are anabontids, and breathe with a labrynth; them dying would not be caused by suffocation by co2
