So ive been doing a ton of reasearch, I have my cured live rock sitting in my tank for about 5 days. I think I want to get a small protein skimmer because originally I thought I didnt need one as long as I do water changes in my 12 gallon but now the thought of water changes scares me, its obviously not as easy as my freshwater. So I was looking at Lees protein skimmer, the fission (so far it doesnt seem great), berlin airlift skimmer. I dont have many options, I have the eclipse instant ocean kit, so my hood and filter is built in so I need one that is INTANK. Any thoughts on the ones Im thinking about or any other options, or do I truly not need one??
