TETRA ALGUMIN 500MLOptimale algenpreventie: Algen in het aquarium zijn geen fraai gezicht en kunnen de groei van waterplanten remmen. Bovendien hebben ze op lange termijn een negatieve invloed op het biologisch evenwicht in het aquarium. Algen groeien wanneer de belichtingstijd te lang is of als er sprake is van een overschot aan voedingsstoffen. Om algengroei te voorkomen moeten de algenvoedingsstoffen fosfaat (PO4) en nitraat (NO3 ) verlaagd worden, bijvoorbeeld met

Algen zijn ook te voorkomen door regelmatig speciale algenmiddelen te gebruiken.Shipping Notes

Excellent sport sock!
Size: One Size, Color: (100) White / White / Halo Gray
Molds onto foot, super soft and breathable. A lot of my ankle socks tend to slip or cut off blood circulation. This one literally is a perfect fit. No slip. After playing hours of tennis every week, my feet don't feel sore or bruised. Must buy!

Comfort!
Size: One Size, Color: (100) White / White / Halo Gray
Very comfortable! Thinner than the picture shows, but I like the fact that they are no show but still higher in the back and front to protect my heels and such.

Sizing way off
Size: One Size, Color: (100) White / White / Halo Gray
These were my favorite socks, at least the old style was. They redid them and I was okay with it. However, I don't understand how they are a one size fits most. I tried them on and they were still too big at the top. There was so much extra fabric at the toes. For reference, I wear a size 8.5 women's shoe, typically. The packaging says fits most from size 5.5 to 12. I don't understand how it fits that wide range of shoe size. Definitely returning these and I will be buying something else.
