Hello , I am using a universal free standing aluminium tower .  I will 
be performing maintenance to it very soon . my 1st question is ... is it 
ok to use stanless steel boltswith the Aluminum ? 2nd  I noticed my 
tower legs which are embedded in the concrete base are collecting water 
.  What is the fix for this ?  thanks for all your help in advance . De
