pure blend pro in a rez

[painter66]

would just like to know if using pbp in a rez that wont be re filled until the end of one week will be ok, as in will the nutes still be nicely mixed or will the pbp have some sort of precipitation happen like a sludge on the bottom of the rez.
I will have an air stone in there bubbling at set times not 24/7
and a small submersible pump to help keep things mixed up but again not 24/7 or would this preferable.

any views and opinions greatly appreciated.

It certainly will get sludgy. if using a wand, shouldn't be much issues, but drippers/sprayers will bung up readily...

thanks bigbag, I don't suppose flora nova would be much better either ? I would think the clay its mixed with will sit on the bottom and need serious cleaning every refill.....

I uses PBP. I mix my rez and then top off with plain water the rest of the week. If the res is areated it will be fine. Never had any sludge problems with PBP.
