So I was reading an article about making a refigium, which I intend to use in a sump/refuge set up in a 10 or 20gal size under my main tank. The article was talking about using specific types of algae for these reason, etc. So I started thinking where do you get these specific types of algae. I did a google search and a search on here and only found articles about getting rid of algae or algae killing products. So where do you guys get your algae from? Online or LPS?
Second question is regarding water changes. I read a beginning a new saltwater tank thing and it says you shound NEVER use salt water to replace evaporated water because it will raise the salinity. But my thought was that if you use fresh water your going to lower the salinity. If you added water that was the same salinity of the tank you would be ok. Now again this is just talking about adding water to replace evaporated water not for a water change. How do you guys do it?
