My nano tank has cycled through a few green and brown algae blooms - no problem with those. But I'm having a hell of a time with red algae (cyano bacteria?) on my substrate. Recently I've been doing 30% water changes per week w/ distilled H20. My clean-up crew does a great job on the live rock and sides of the tank - but nothing will touch the substrate with this red guck on it - even the burrowing cerith snails. I'd like to add another sand sifter but I don't want to waste my time if they won't touch this stuff. I'm looking at blennies/gobies but nothing seems to be right. Any suggestions?
14 gal biocube w/ new Coralife 24 watt 10K and 24 watt actinic - 12/12
I ended up adjusting the flow nozzle downwards towards the substrate and this has improved the cyano bloom significantly. I'm thinking of upgrading the biocube pump anyway so perhaps I'll use the old one as you suggest.
