RE: biocube HQI upgrade
I have read some good things about nanotuners on other forum sites. As far as this MH upgrade I would worry about heat build up and acclimation for the inhabitants. It looks awful close to the water and the hood does not allow for raising it higher. You would have to probably upgrade the fan as well if it does not come with a new one. If you decide to get it please let me know how it works out, I would be interested in one for my Biocube 29.
