I gave it 4 stars as the pump does the job and is very quiet. my only issue is that it has a stand and holes for feet but not rubber feet were provided. Had it come with the feet I would have given it 5 stars
This pump is amazing. It literally works twice as well as my last one, makes less noise, and costs 30 dollars cheaper. I wish so much I knew about this one before I bought a replacement for my other tank.
I bought this pump for my system to find it was just too strong. The pump itself worked very well and did what it was supposed to, not too loud either.
