Cut my hand open that evening trying to cut my sock holders out to install a clarisea. Spent the whole night in the ER waiting to get stitched up then caught up with the holiday. Anyway, I ran the skimmer in a bucket right before he picked it up and it was running fine (it had been running like a champ up to a week prior). It was sold and shipped to me as a 600. Never thought otherwise. I’ve been running it this whole time thinking it was a 600. It seems going back through texts, he texted 8 hours after he picked it up to say it doesn’t work, which I find it very odd because he had a chance to check if it runs when he picked it up or you’d at least think to check as soon as you get home (takes 2 seconds to plug into an outlet). I’ve been around here for quite some time and have dealt with SEVERAL members with no issues and give out free items/tanks all the time. So not entirely sure since I tested it before he picked it up. Let me know what y’all think
