I know there is a section on here for results of successful scrubbers, but is it not time we asked all on this forum of their results, both positive and negative.
We all know now the requirements in terms of lighting, flow etc so anyone who is scrubbing a 150 gallon tank with a 11w bulb need not reply.
What is needed is the results of properly constructed and maintained scrubbers, and whether they did indeed give the intended results, i.e no phosphate, nitrate, display tank algae.
A rough idea of the timescale the scrubber has been running would also be useful.
It does not need to be an essay, just a brief outline.
