The tips look like they have lost tissue and it is turning brown lost most of its red. Test kits are api, crap I know. I use elos for everything els.

Be carefull with the API test kit. I had one that was giving me 8 as reading and when I tested it with another kit I was at 14!!

Good thing that did not cause any dammage to anything but a test can turn bad. Mine was ok at the begining showing the right thing but as it grew older it started to give wrong mesurement.

I'm going to pick up elos ones tomorrow.
