|  drawbacks with CO2 ok...so when using pressurized CO2 how does one control the pH ..my tanks now have a steady pH of around 7.4 thanks to a nice bicarbonate buffering system with my eco complete...without the pressurized CO2 this system with stay for around 5yrs or so...with pressurized CO2 the buffer system will deteriorate in 1-2yrs and thats when the pH will no longer hold spike in acidity..right? and the only way to go around this is to add baking soda?...Can you buy calcium bicarbonate rocks online? Or is changing out the substrate every two years a must? Anyone experience this problem after two years of pressurized CO2 use in their tanks? Any tips?

| Are you trying to harden your water? I think putting crushed coral or limestone in your tank will keep pH high and stable.

| I'm not exactly sure what you're tyring to ask, so I'll just take a random stab. You do not need a buffering "system" for a planted tank. CO2 only lowers pH by creating an acid in the water. This only lowers pH, but it will never lower pH much past a pH of 5.5 or so, which is an enviornment that most fish and bacteria can still inhabit with ease. The lack of a buffer (KH) to avoid wild pH swings is a myth--it just doesn't happen. If you do have a light buffer, say your Eco Complete, that's ok. Heavy buffers like calcium carbonate based substrates (or any addition of CaCO3) will cause problems. To be honest, a buffer is actually discouraged in a planted tank. There's no need for one, and regardless of the substrate you use, they will all turn acidic eventually, which is an ideal condition for aquatic plants. You should never have to change out a substrate, but a really good cleaning every now and then (twice a year) probably wouldn't hurt.

| Ohh..ok- thanks! Yeah that was the random stab I needed for my question
