IO regular vs IO RC!
 

I am currently using IO regular but since I have started adding pretty corals (no SPS; they are just way too challenging for me and I like things that moves with flow :D), I was thinking whether I should start using RC. My current system does have a 440ppm calc but I don't know about magnesium since I don't have its testkit.

So should I stick to regular one or get a RC for 20 bucks more.

Alongside, even if I do change to RC, can I mix the salts or should I do a big water change with RC to replace the regular mix in the system?

Thanks :)

Honestly, until you know why you need to switch, stick with IO and save your money.

Haha yah. I was getting mixed review about using IO regular for reef so just wanted to know what experts over here got to say :D

Look at the favorite salt poll, overwhelmingly IO used in all kinds of tank setups. You're not going to go wrong using IO (mostly) :)

Hi: I am by no means an expert but have been using IO since I started up my reef tank. I just keep softie's and LPS and they are doing well with it.
I heard about IO reef crystals, but use only IO reg. I think if it ain't broke don't fix it. :smile:

Thanks everyone. I guess I will stick with regular IO for now. Will be getting a bucket so wanted to make sure that I am getting the right stuff. I also have only LPS and softies (other than red monti) so I guess I will get IO and save the $20 for a maxi mini :D

The difference in chemical makeup between IO and IO RC can be made up with a few cents worth of bulk chemicals. I would also save my money and just use IO.

So I am considering RC as just a fancy name :P

Looks like IO actually has better traces than RC :| Weird!

In Greater Vancouver, we have one LFS that sells IO 160g buckets for $29.99. Can't come close to beating that anywhere. That's one reason why so many local reefers use IO. It's by far the best deal on salt in the Lower Mainland.

That's darn cheap :O I think the lowest in Calgary hits around $45
