So bought the RO unit and following comments, on this forum added the DI pod, and produced the water. Was recommended to buy the Red Sea Pro and having read the instructions I’m wondering if I’m over thinking? My plan is to mix the salt, using a small power head, at a temperature of 20 degrees for circa 2 hours by which time salt should have completely dissolved (Red Sea video seems to suggest this timescale)...and once dissolved only increase temperature to 25 degrees just before I’m doing the water change to avoid precipitation of key elements. Am I over thinking this?
