I've using distilled water in my biocube for about 6 months now. No major issues as of yet, some algae breakouts here and there But I'm ready to get an
ro/
di unit. I've been looking at the spectapure 90gpd refurb unit for $125 and the bulk reef supply value system for $130. The seem pretty similar and both appear to be upgradeable if want to add some other features later on. Does anyone prefer one to the other? Should I be looking at other units besides these? Thanks
