C02 and Plant Problem - Please Help
Iâ€™m just new with using CO2 and my local aquarium has told me to turn it on and slowly increase the CO2 and use my PH to tell when I have the right setting.
My problem is that some of my tetras will start gasping for air and breathing rapidly at the surface of the tank, before I have even seen a change in my PH. My tank if about 4ft and is not heavily planted yet as I want to get all my problems worked out first. I have some different types of swords and a few Crypts in there right now. Things where going ok until around the same time I tried using flourish excel, instead of just the plain flourish. My swords are getting little brown circles in them, and then the leaves would start browning from the edge and die. I took a few leaves to the aquarium and was told that my bristlenose where doing it, so I removed them and I am still having this problem and the people at the aquarium have told me that it canâ€™t be the flourish doing it. I have taken a water sample to my aquarium a few times and it has tested fine. One thing that I have noticed is that my plants donâ€™t seem to take root as well as the ones in my other tank which is running on a much lower light level without C02.
Has anyone got any idea with what is happening with my swords and how can I tell what setting to have my C02 at.
