Sponges filter water, most (all that I've read) references suggest they are good for the system. Some people promote their growth.
I clean them from my sump

i took some in to my local fish store and they said it kinda looks like sponge but then again it looks webby. and my chatos has gotten smaller??

Up to you. I syphon it out with a hose, but I clean my entire sump.
I have had other tanks where I don't, either way I don't feel it should be an issue.

If it was to die in the tank, it may add to the bio load.
It is posible its a bacteria, but it looks like sponge to me.

and whats yalls best way to get your daily dosages for alk mag and cal? was told to bring levels where i want them then wait a week then test and divide what i used by 7?

What ever works for you.
I use this calculator http://reef.diesyst.com/chemcalc/chemcalc.html
My tank would be dead if I stopped dosing for 2 days, let alone a week
Your consumption is likely to change with time, I make adjustments every few weeks, as coral mass increases, so does consumption
