man I will tell you what its a labor of love, these frag tanks have been such a headache and sooo much fun at the same time. right now I have 4 running and getting ready to fire up 4 more so I think the fun is just beginning!!!! I am very excited to run the t5's on the 4 new tubs, they are so much better for growth. the 4 I have now are all under MH with actinics so it will be nice to see the diff in the 2 types of lighting!!!!
