DIY C02 reactor Cannister or Ladder
I am going to be upgraing the lighting in my 55 tonight and would like to add a simple DIY C02 reactor. I use a fluval cannister filter and I have one of those C02 ladders from another system. Which one should I feed the airtubing into for the best results?
If it was a toss up or close to I would prefer to use the cannister and save the ladder
