i just purchased a kalk reactor from reef-tech . Great product by the way ! my question is i have a dosing pump from www.innovativeaquatics.com/ . great product as well ( natulas II) it has a high volume tubing set. my question is what do i use to join the tubing from the dosing pump to the tubing from the kalk reactor. and most important can i get it locally ex-- home depot or lowes or something. i would imagine i need a reducer but cant find a place that sells one small enough . any help i would greatly appreciate.. thank you !
