What'd be interesting is not just what people are using but what their salt tests at for calc/alk/mag (before adjusting) when they mix it up with RODI. That'd be very useful knowledge.
I am currently running Tropic Marin Reef Pro but I am looking at switching to Fritz since my LFS handles it.
The last two batches of Tropic Marin have not mixed cleanly so I have had to run filters on the containers. This seems odd based on everything I have heard/read about this salt.
