I checked on my Grobo last night and my air stone isn’t working… I’m not sure how long it’s been down but plant still looks good… Figuring I need to replace the pump… (haven’t taken apart yet)
Since I need to replace it I’m looking to upgrade the pump to reduce noise… I’m not looking to reinvent the wheel on this one. Looking to see if someone can share what they bought for a replacement pump and save me some time.
Thanks
