Negative Positive
Title: updated review
Review: this thing is noisy (from the impeller). Its installed correctly and I went through the troubleshootingsection even though its pretty basic on how to install everything. I have older bio wheel filters and they seemto have cut corners in the quality lately. I emailed the company to see if they will send me a replacementimpeller and they do not even bother to reply. Time to go to a company that makes better products and cares about the consumer..UPDATE-I rec'd a new impeller from the seller few months ago and it has been very quiet. Keeping the tank crystal clear and all of theparameters are within normal limits.
Is the review positive or negative?
