Well, I didn't win any of the UK auctions for regulator bits and pieces as the prices were going higher than new kit from the far East.
There again, I have not bougght any regulators or Solenoids from the far East as I am worried about quality. I need to look into it a bit further yet.
I've got my CO2 running. I need to get a solenoid, that's the only bit that's missing.
Does anyone know how the first few days with CO2 pan out. How will it take plants to pick up on it, when they were all pretty much alive but in hibernation.
Any ferts good to give them a kick? I was thinking Potassium Phosphate?
does adding extra co2 to the water actually affect the fish?
No, not if controlled carefully via a regulator. There is also a drop checker to help monitor which works by detecting the ph change caused by CO2
and likewise does adding an air stone to the tank (o2) affect the plants?
An airstone shouldn't really be necessary for a large tank with surface movement, and can actually be counter productive for plants because high oxygen levels will drive out CO2 which the plants need.
Unless you have a specific need to run air stones (like to break up surface protein) I don't think it is helpfull to a planted tank.
