Heya I'm getting some equipment rounded up. I've decided on the Octopus Needlewheel 150 protein skimmer. The other item I have been working on saving for is a calcium reactor. I have the cash for a 150 or so dollar one. But I don't believe it is going to be a quality one. What has the best bang for the buck when it comes to a reactor. I can afford a co2 tank and a 100 or so dollar regulator. Give me some advise please, if you've used it and it works well that advise would be best haha Anyway I have this 55 gallon tank but in the future I intend to upgrade it to a 120 gallon. Thanks!
