I know the answer to this is to perhaps get SeaGel (hence my previous questions on it) but i have a fair bit of Phosguard AND Martix to use up.
Was just thinking, can i put both in my reactor? Perhaps
phosguard | foam pad | matrix | foam pad
This way i can give the phosguard more room to move a bit, but pack the matrix a bit tighter to give it less movement. Its only a little reactor, but then its only a little tank so i dont need much of either.
Just thinking it could be a way of getting the matrix bag out of my sump
