Hi guys got my first nano tank today. 29 gallon biocube. Before i start it up had a question on protien skimmers. Was wondering if any one has tryed the skimer made by saphire aquatic and is it worth the extra cash over the biocube skimmer that is only 34 dollars. If its worth it i will deffinatly wait and buy it. Also is one of the hang on the back refugums a worth while investment for my tank or should i just mod the midle compartment /and or do the power filter refugim mod. Thanks for any help i realy want my first tank to be a success.
