Cannedfish Posted May 11, 2018 Share Posted May 11, 2018 That could also be nudis... yikes. Quote Link to comment
Svpeters Posted May 11, 2018 Author Share Posted May 11, 2018 Yikes is right. How do I get rid of them. All corals dipped before adding. Do not have a quarantine tank. Have looked with magnifying glass not sure. Quote Link to comment
Cannedfish Posted May 11, 2018 Share Posted May 11, 2018 Wait a couple hours after dark and check with a flashlight, they are slightly smaller than a grain of rice (look online for pictures). Also, it may not hurt to give it another dip. If it is nudi's its likely that you killed the adults with the initial dip, but the eggs remained. Lastly, if it does turn out to be nudi's, hopefully it's your only monti. If it is, and it doesn't make it wait a month or so before adding another, you want to make sure they are dead before adding a new frag. Quote Link to comment
Svpeters Posted May 12, 2018 Author Share Posted May 12, 2018 Checked as above and no nudis Used magnifier and light. I do have some vermetids. Could this be from them. Was going to transfer rock from aquarium to upgrade Red Sea 170 but now wondering if I should start from scratch. I know there is no guarantee I still may have pests. Montipora firmly attached to rock. Should I leave alone or use tool to remove it. Thank you. Quote Link to comment
rsucre Posted May 12, 2018 Share Posted May 12, 2018 Hi. Assuming it is not nudis.... I had a similar situation, a few times already, when my NO3 and PO4 are very low and KH is above 10 dKH. I'm not sure, but I'm attributing it to the combination of parameters (low nutrients and KH). I have found many threads talking about ULNS systems being more susceptible to KH and that you must adjust for lower KH. Since then, I try to keep my KH at 7.5 - 8.3 dKH. Quote Link to comment
rsucre Posted May 13, 2018 Share Posted May 13, 2018 You may find this interesting. http://www.marsh-reef.org/marine-and-reef-chemistry/50255-ulns-higher-kh-=-alkalinity-burn.html Quote Link to comment
