top off water
 

i was just wondering if anyone ever gets a thin layer of an almost scummy surface on the top of their water change water. it just looks like a bunch of little brown floaty things. and if this happens is it ok to still use the water or should i discard it and mix up new?

Normal..... especially with Instant Ocean salt.:biggrin:

huh? are we talking about water change water or top off?

Sounds like your using IO salt. It's normal but I have no idea why. It looks clean before you mix it

yep sure am using io. hahaha thanks guys :)

this just makes me ask why does everyone use / recommend it???? ( ok not everyone but ....... ) i tried it for the first time this year and never again will it be near my tank.

I don't tell people IO is better then other salt brands but I've used IO for the last 15yrs with good success :biggrin:

I've never had any issues with IO. Thousands upon thousands of aquarium reefs use IO.

Cuz its cheap.

When I first started out in the hobby a 50g bag of IO cost me $44, this stuff was white gold :lol:
