I just want to get a general consensus from those who may be using algae scrubbers. (I'm not even sure if there are many of you out there.)
I've had one set up for almost a year now, and I've had 100% success with it. I know that it's not for everyone, but I have a small system which allows me to get away with a small scrubber. Mine is simply set up in a AC70 hang-on. I didn't even follow the most recent research on algae scrubbers to set it up. I just used a few bits and pieces of information and put mine together using common sense. Works well. Haven't had one strand of hair algae since.
One thing I have noticed is that once I got my scrubber going, my macro (chaeto) stopped growing. It's now all but dead. Now, this makes sense to me because the nutrients are now being consumed by the hair algae on the scrubber. So, this leaves little left for the macro. But, from what I understand (or what I thought I understood) is that macro is more efficient at removing nutrients than hair algae. Otherwise, there'd be no point in using it. There may be many scientific variables involved here, but that's always been my understanding. In fact, many recommend removing the macro from a scrubber system so that the scrubber can function. I experienced the exact opposite. My scrubber put my macro out of it's misery.
For those of you using algae scrubbers, have you experienced this? I'm going to have to pull my macro now, but I feel strange not having it. It's not growing anymore and it's all hard and crusty. I don't NEED to have macro if the scrubber is going to work as well as it has, but I've always had macro in my systems. Just wanted to hear what others have experienced.
