RC or IO

I need to switch salt mixes. Fritz RPM has disappointed me and the company attitude sucks, but enough about that. IO regular or RC? I have a mixed tank corals are nothing special but I have a lot of them. My params are Ca 550, Alk 9 and Mg 1700 because of the Fritz product. Also considered Red Sea and Kent Marine. Seems like there is no clear consensus. Suggestions?

I personally use regular old IO(purple box), but I match my display with the big 3. I used to use RC, but did not like how it had that brown crud from sitting in a mixing barrel.



Regular IO mixes up to about 390 CAL, 10 ALK, and 1200MAG. I've used almost an entire pallet of 200G boxes, and these numbers are pretty consistent for me.



Little CAL and MAG supplementation, and muriatic acid to lower the ALK to 8.5.

A lot of Tanks of the Month have run on IO. I agree that the brown sludge is a bit of a mess, but it will not harm the tank.

I used RC from the start and about 6 months ago I started using Fritz RPM because of the brown sludge RC leaves behind in the mixing barrel. If I was going to use one of the two, then I would use IO. It's gets old scrubbing the barrel after you've made the batch of saltwater.

I've been doing a lil mixing and matching. Was thinking about switching to Fritz but after finding several thread regarding wild variations I think Ill stick with my mix and match.
Typically Ill test a day or so before a change, since I mix up only about 15g the day before.

Regular IO, Reef Crystals, and Red Sea. Generally I like the boost to Cal I get from the Red Sea and using one 5g bucket is 1/3 the WC thus lessens the impact of increasing Alk from the IO & RC.

I should just be able to find one that matches, but consistency and availability is seemingly tough in this market.

FWIW 1.026

Instant Ocean 400 11 1350
Reef Crystals 490 13 1440
Red Sea 410 7.7 1280
Red Sea Coral Pro 450 12.2 1340
