Can’t tell from your pics but algae and sand in the seams is how it starts. Consider yourself lucky to have noticed it. I would prepare to break it down asap given Red Sea tank reputations.
Not sure yet fishy. I have to see what they’re selling for and take in consideration if you’re taking all 3, and if dealing local. I’m in Jersey as well. Shot me a pm and lmk what you’re looking for and maybe an offer. Thanks.
In case anyone is looking to trade their xr-30 g6 blues from pros shoot me a message. My pros were purchased on 7/16 this summer (I will show receipt from BRS). I didn’t get them running until august. I have 3 of them. Perfect condition have boxes as well.
