pump to reactor question

So I installed my dual gfo and carbon reactor and it seems to be running great. I used a maxijet 1200 (what bulk reef recommended) and the half inch tubing that i used isn't tight in the connection and it's leaking. So is there anything like a plastic hose clamp or something I can use to make it tight?

Also I have my reactor about 4 feet under my pump and water level. I've been thinking about drilling a few holes in my wall and installing the reactor in another room. I'm hesitant to do that since I rent an apartment but I will definitely do it if it would be better off for the aquarium.

thanks
