Slide out bracket danger?

[skydiving]

I was checking out my freshwater tank mountings on my 24ws. I noticed that one of the brackets or guides from the slide out are touching my freshwater tank. The other is less than a 1/4" away from touching the tank. I took two pictures. The first one is not touching but I can see marks from where it had touched the tank. The second one is actually rubbing against the tank. Has anyone has their freshwater tank damaged because of this?

It's hard to tell the damage/ severity from your photos but if it's touching and/or rubbing the tank, that's not a good situation to have.
