To all you Xenia fans. do this little experiment.
Xenia is what got me into this addiction so I can certainly appreciate when someone gets bitten by the "God help me!!! I will get them to pulse!!"
Sparing hijacking this thread into a 3 foot long dissertation on my trials and research (not a pro, just was almost driven crazy by Xenia a few years back) this is the nitty gritty.
If Xenia arent pulsing, give them more 10k light. dont believe? me take a frag, toss it in a plastic bag and hold it closer and closer to a 10k lightsource, they WILL pulse regardless of water flow/quality/elements/ect we all normally live and die by (within reason of course). Just keep an eye on temp being so close to the light. They are tollerent but I normally run tank at 74, they were pulsing from 74-80 with no real preference to temp, flow, salinity,ect, they just love 10k and lots of it.
OK thats my two cents worth and please remeber I am a self proclaimed Idiot...yes notice the capital I. but hope this helps someone out there thats in that infamous rut of trying 600 ways to get them to pulse again. Thank you to everyone for bearing with my ramblings.
