Review on 🐠 In-Sump Protein Skimmer for Saltwater Aquariums up to 120 Gallons Fish Tank by Brook Johnson

I bought this skimmer 5 weeks ago and today the pump started making a loud grinding noise. I cleaned the pump, didn't help. This came a week after Revain's 30-day return policy. I looked through the listing but couldn't find how to contact the seller. **UPDATE** IOAOI immediately sent me a replacement pump. Excellent customer service. I give 4 stars because the pump shouldn't have broken. Hope the replacement works better.
