Wierd Lines after Tank Filled

[TeenReefer]

My tank has been filled for three days now and lines left behind from the foam when i filled up the tank have been left behind. I have tried scrubing them offf w/ paper towel and rags but nothing has prevailed. I also used a dab of bleach on a rag to attempt getting off some algea during the tank cleanout. I dont think the lines are a result from that. I dump 2 gallons of mixed saltwater at a time to fill up the 30 gallon tank, and you can see the 14 - 15 lines in the pic. Will they disappear with time? Thanks!

If you can't get the lines off with a little elbow grease, try scraping them with a razor blade

a razor blade will fix this, as per bound said..

What has caused this though? Just the foam from the fill or are they hard water stains?

I had lines in my tank after the fill-up but a soft bristle brush wiped them right off. I have no idea what could be that hard to remove.

The Razor Blade worked! Thanks bound_for_obox for the idea!

its just the salt deposit from the fill up, glad to see its fixed..!
