I'll be transferring my soft corals, SPS, and LPS to a new tank soon and want to limit the chances of introducing some nasties I accumulated the last 3 years my tank has been running. Namely briopsis, bubble algae, and dictyota. These seem to thrive no matter how low the nutrient levels are but haven't really gotten out of control, just a PIA. The bubble algae is easy to pluck out from time to time, I can beat the briopsis by running high magnesium, but it inevitably comes back. The dictyota is slow growing but but is really hard to remove. Lucky the new tank is larger and will allow me to pick up a tang to graze on the greenery. If I can avoid any or all of these, I'd be really stoked! I won't be transferring the rock over, but some of the coral bases that are no longer covered by living tissue and frag plugs could have small amounts or algae spores. Two options I see are taking a dip in coral Rx and scrubbing/scraping the bases down. The other is more aggressive and using diluted hydrogen peroxide to either dip the whole thing or just the base. I have some pretty large colonies I'd hate to loose in the process like a big birds nest, montiporas, torches, and some small acros. Anyone have any success stories or have used hydrogen peroxide safely? Sent from my iPhone using Tapatalk
