ROSA things in the aquarium?

I have a filter tank heated two gallons for my betta with gravel and there are things ROSA everywhere. Is inside the air glass pump (like glass turned pink) tube pink turned its starting to make its way to my pipeline and filter my aquarium glass top seems clear, but when I came across a wet tissue, tissue filled all things pink is like a red marker mixed with water … is the shadow that ammonia does IDK mean or what is this? its not Slimey is not strong as anyone in color, but that has not every Saturday: 35% change of having a filter plate, and a whisper internal filter to clean the poop of suction in a dropper thing (similar to the turkey baster) no more food is always in the tank to feed my Betta their pellets

blurred or Slimey? could simply be a layer of algae or fungus growing bacteria and the color of food is fish you feed the fungus grows in the food so the color shows through, bacteria and algae build up in layers and usually look brown, but some are different and perhaps food some color filters the only way I know you have ammonia is getting one of the test kits for him, but the ammonia must be changed to nitrate in bacteria. nitrates can cause algae to grow, so if things are pink algae, could mean that you have lots of nitrate and the need to clean the tank more frequency or more changes of water. How to use a gravel vacuum to clean the gravel (good) or just drink water with a cup (not good). If you are taking food water and poop builds up in the gravel and not leaving everything you need for pipes and pipe line filter makes this sound like using a filter plate the tank. a filter that blocks on the side of the tank works best. but has yet to make weekly cleaning and water change
