I'm purchasing one of these for my 150 gallon but wanted to see what people think of these. It says you don't have to add the liquid to this one but I still do not know enough to put it in my tank.

As you'll hear all of the time in the hobby, take everything with a grain of salt. This included. I have seen my nitrates drop from 80 to 20 in two weeks with this tool so I recommend it to anyone who has thought about getting it or just needs the extra help. I'm no pro but this thing seems to be really helping out.

I have my first issue. The rotten egg smell. It's been up for 2 weeks and I read to up the drops. Should it be drops or a steady flow? Any tips are appreciated.
