thanks kathy.!
i was concerned since the mag light shines a relatively bright column of light down to the bottom of my tank, since its only 1 foot deep. i was concerned larvae would hang out on the bottom.

thank you, i put duct tape to form a small slit , but ill try to reduce it even more.
kathy, after you turn off your pumps, when do you add your snagger and turn on your mag light? thank you.

LOL
A light coming from the sky, the little guys feel attracted then something sucked them inside and they are taken to a paralel world.  Sounds like abduction! Sorry  Anderson.

Sequence of events:
Turn off pumps 15 minutes before lights out. (turn on bubbler. I am absent minded and I don't want to lose my broodstock. If i forget to turn the pumps back on, the broodstock will be OK with just the bubbler.) Install snagger, plug in minijet, adjust level. Lights go out Wait impatiently 30-45 minutes later, larvae arrive When I don't see any more larvae enter the box, and a quick flashlight check reveals that the eggs have all hatched, I turn the lights back on. Lift the corner of the box to raise the hole out of the water, and simultaneously turn off the minijet. Remove minijet from box Carefully remove box and immerse/pour larvae into larvae tank. Marvel at the tiny wonders! Rinse snagger and put away Turn parent tank pumps back on, and thank the broodstock. Start a freshwater drip to reduce salinity in the larvae tank. Turn all the lights out and go to bed. In the morning, I take a digital picture, then I add live phytoplankton and enriched rotifers. If I am unlucky, I siphon dead bodies out of the tank. Luck has been with me lately, but you never know... |

Lowering salinity for larva
Kathy,
Thank you for posting your routine! That is very helpful. This is probably a dumb question from a relatively new breeder, but I don't ever recall reading in Wilkerson or Hoff to lower the salinity in the larva tank. What is the benefit to this? Does it increase survival of the larva? Thanks, Jamison |

Thanks embryoguy! It has been a while since I read Wilkerson's book, I must have completely missed that.
Hopefully that will help my success rate go up! Jamison |

matt my snagger really worked well!
at 45 min, most were in the snaggger before i even shined the flashlight, so another 15 min of flashlight i picked up most of them. i saw some straggers inside the tank but decided to pull the snagger to get the majority into the larvae tank.

ok so is that like an acrylic box like a specimin container with a piece of acrylic as a spacer? and i see the powerhead but where is the outlet on the powerhead going. i see the suction on the bottom but i dont see where the water exits.
and what kind of light is that? sorry for all the questions but im trying to figure out exactly what i need and your design looks solid

its actually a cpr intank refugium
and yes it is acrylic. the black divider is a spare part i had laying around from a filter. it has slits in it as you can see. i also cut apart a brine shrimp net and aligned it over the slits. there is a hole from where the rio 40 exits. that was premade. it was designed that way to work as a internal refugium. i put an adapter on the outlet so i can adjust the flow of the pump. i cut out a small square as the inlet. the light is a simple moon light. im going to switch it to a white light though.but like i stated, this is my first attempt to collect them, so i can not know for sure how reliable this setup is. i would advise asking the other seasoned breeders with more experience and expertise in this area on the premise of a snagger. i think theres is prob. more effective.
