Microbubbles from RO?

Hi all,
I am posting this in the salt forum since I started with a salt issue. While I was checking my salinity yesterday, I found it to be at the top of my desired scale. My hydrometer was reading 1.024 at 78 degrees. I then decided to top off the tank with a little RO H2O without salt. I also added one drop of iodine since my xenia was looking a little flaccid. I now have quite a few micro bubbles in the tank (about 24 hrs now). Will fresh RO cause this, or could it be from the iodine?

Thanks in advance.

 

The microbubbles are being created in your skimmer or perhaps your filter/pump. The iodine is the likely cause. I've never seen a post on 3Reef that attributed microbubbles to topping off with fresh water.

 

Thanks Saw39. They went away about 48 hours after the addidtion of the iodine.

 

R/O did not cause it and the addition of Iodine did not cure it..

 

I wasn't thinking that the addition of the iodine cured the microbubbles, I was thinking that it may have been the cause and just settled down after 48 hours.
Your thoughts?

 

I don't think I ever heard of low iodine causing bubbles in fact I and most I deal with never does iodine in fact there has been many studies and research on its use and there is still no way of telling if its even used by or need by corals. Its simply a heavy metal that acts as a antibacterial agent i use it for dipping all the time.. But I have never put it into a system here at home or at the shop.. If you re like many then then the water changes will supply all that is needed . Its often though that many crustaceans need to to molt , But many have found it just forces them to molt rather then to help them molt. A molting laxative if you will .

 

A molting laxative? Ewww!
