I don't understand your question fully, because you cannot get albino spiders from regular albinos.
To get albino spiders, you must have 2 copies of the albino gene and 1 copy of the spider gene.
This means you need 2 of the following as long as one parent is one of the first two and the other parent can be any of the 4.
spider het albino
