Hi

I just set up my 75 Gallon tank about 2 months ago after 10 years in storage. I have a few swords, hygros and crypts in it and I plan to add more in a little while. I have 6 fish in there at this time as well and everything appears to be getting established and stable.

My questions is why do my plants start to bubble so well after I do water change? I have a DIY CO2 system that I am still fussing with the get enough CO2 into the water but I can never get the plants to bubble. However, within minutes of adding new water after a cleaning, everything but the crypts starts to bubble!

My latest water tests were PH 7.2, Hardness 150 ppm, Ammonia 0, Nitirite 0, Nitrate 0.

The way I figure it, two things happen when I clean the tank and do a water change. 1) The water gets very well arated (oxyginated) because of all the spashing from the return, 2) The fresh water must have enough CO2 in it to trigger the bubbling.

I suspect number 2 above is what is causing the bubbling. Am I right?
