Ron,
I pretty much followed the advice of a poster over at nano-reefs. He is pretty much known as the man of the BC29 with all the mods he has made to make the BC29 really efficient.
Got my BC29 today...... - Nano-Reef.com Forums
I made all my mods over a few months, sapphire
skimmer in 2nd chamber, modified flow from 1st to 2nd chamber, Rio 6hf return pump with loc-line splitter for two return heads, one is hydor flo and the other a normal head for surface agitation. Upgrade lighting NanoTuners 144w upgrade with better fans.
The BC29 is a beautiful tank but they didn't really put quality thought into the filtration system ie terrible carbon filter, I used a dremel and took out the carbon in the filter and now fill the filter frame with filter padding which allows for better flow through the filter. Bio balls are a terrible for fitration as it contributes to
Nitrates.
Here is my stock list: 29 gal Bio Cube, Nanotuners 4.36 144w light upgrade, Sapphire Aquatics BC29
skimmer, Rio 6hf main with locline return splitter, hydorflo, Candy Coral, Zoas, Green toadstool,
