zip ties gone pink?

[Mr.V]

i made a tank divider out of some .5 inch pvc and plastic window screen which is held together by some small opaque white zip ties about a week ago and now the zip ties are turning pink in color. what does this mean?

 

[señor_pescados_felices]

I dunno but mine did that too......

the uv light from your lights are probably affecting the plastic use in the tie straps.

Same thing has happened to me any time I put white plastic type stuff in an aquarium. Solution? Try black?

 

[Dr Joe]

Some plastics are also more susceptible to particular algae growths, it doesn't always scrub off either, so if you don't like it go with jwarriner suggestion .

Generally the formation of a pink film in damp or aquatic environments is attributable to the growth of a bacterium called "Serratia marcescens". This is a harmless bacterium, but don't get it in your eye because it can cause conjunctivitis. Wash your hands after handling these parts.

i thought it was just cuz of acidic water... u know how they do redox reaction tests??? i always thought it was cuz of slightly acidic water
