Yes

Silicates will usually go away when u eliminate the source of how there getting in the tank. But from my experience in the past they got locked in my sand bed and I had to slowly remove all the sand out of my tank.
But silicate are not for easily removed by your regular RO system. They are like glass and cause you to go through membranes twice as fast. You need to have really heavy duty carbon blocks and what I have found that works the best is a silicabuster filter as your DI.

What of salt are you using. Did you recently switch different brands? I had a similar issue when switching from H2Ocean to Reef Crystals. I switched back and everything cleared up, maybe just a bad batch of salt.

Yes Rowaphos removes silicates but not all gfo does. Also a silicate buster for your rodi system will help. NSW and salts have silicates but if elevated will cause algae problems. hth
