How to>

Hey I bought a used tank that obviously had an attack of algae. I was wondering how to get dried old dead algae off the magna float, and these weird white tip of pen sized things off of it. Soaking it does nothing. grrr

 

Soak it in a 50/50 vinegar/water mixture then scrub like the dickens

 

Thx~~~~

 

Along with what Amcarrig mentioned, those white things(spirorbid worms) should be able to be removed by using an old credit card or comporable scraping tool-making sure that you don't scratch the glass/acrylic tank, however!
Good luck...

 

Thanks!
