Hey there everyone! If you want to skip all my chattering, skip down to the TL : DR section. I'm a new saltwater tanker/reefer whatever you want to call me. I have lots of experience in freshwater fish of all types, from goldfish and bettas to cichlids and oscars. However, saltwater has been a whole new beast for me, especially since I am doing less bargain hunting and piecing together as I go, and more "let's get this set up right the first time". Since I have the funding at the moment, I decided to go all-out and put the money in up front rather than having to go back and "fix" things later. To start, let me give the specs I currently have. Mechanical Specs: -- 29g Coralife Biocube with a retrofit 24 LED lighting system from rapidLED - I prefer natural light to more of a blue light -- inTank media basket: filter floss, purigen, chemipure elite -- inTank refugium basket: chaeto algae -- no skimmer, I've chosen to do weekly 5% water changes to help remove unwanted impurities and replenish trace elements since it's such a small tank. I use bIonic salt mix to achieve a more regulated mixture of trace elements each time. -- mp10w ecosmart pump, heater, the standard 'tank' stuff -- The biggie! Apex system, with ph, orp, and salinity probes to monitor. I know orp isn't a big deal, but it came with the package I got. I still check salinity with a refractometer, but I feel the probe provides a peace of mind for when I am not at home. -- One portable RO/DI unit In the display tank, I have some base rock and caribsea arag-alive "special" grade reef sand in fiji pink. I don't know what makes it "special" grade, but I knew I did not want super fine sand and I certainly did not want crushed coral. This was a nice mix of mostly sand with a few bits of crushed shells to add texture. It's about 1.5"-2" thick. Today I was finally able to add some live rock to my tank. The place I got it from had it on sale, and I loved how the pieces looked. I inspected each piece and found that there was no black areas and it smelled healthy (ie, nothing rotting). However, the reason I think it was cheaper was because it was broken down from someone else's old tank, and there were a few polyps of aiptasia growing in various little holes. The man at the store helped me clean off the largest ones via that paste stuff that kills them, but I can still see a few now poking out of their holes and saying, "Oh hey! Look! A new tank to take over!" With nothing in the tank aside from just the live rock, I'm ready to do battle and get rid of these guys. I know I can use the paste, but it may be hard to get in some of these little crevices that they are hiding in. Plus I'd like to do a more natural method of controlling these pests if possible. Someone suggested to me to use peppermint shrimp, but I have heard they do not always work, especially if food is available. Seeing as I have nothing else in the tank, once my parameters have stabilized, I could add one or two of the shrimp and see if they are going to eat the aiptasia. Alternatively, I heard I could also use berghia nudibranches. These little guys supposedly only eat aiptasia, and they die off after about 6-8 months. They will readily spawn and their babies will easily get into the cracks and crevices to eat all the aiptasia that is hiding. There is virtually no chance of them taking over a tank as they stop reproducing and die off once the aiptasia is gone, and since they're so tiny, they don't really impact the tank parameters. TL : DR Should I use a mixture like Joe's Juice, peppermint shrimp, or berghia nudibranches to kill and control aiptasia that hitchhiked on some live rock in a 29g tank that has no livestock, only live rock/sand and some base rock? Thanks in advance!
