Amount of air on eggs

[hvacman250]

When pulling the tile from the display into the larvae tank, how much air do I put on the eggs? What shape/type of airstone?

I know its hard to describe, but I was concerned about TOO much airflow and about half the eggs turned milky and didnt hatch. I'm assuming this is from not enough flow over the eggs?

Can anyone describe or is there a video somewhere?

I don't bubble the air on the eggs, I bubble it past them. The bubbles never hit the eggs, but the current does. I tend to run the air stronger than most because of this. In general, I run the air at a speed that I can still count the bubbles, but just barely. No air stone.

Are you using rigid airline to bubble?
If you had to guess, how many bubbles per second are you counting?

I have the tile at a 45 degree angle resting between the heater (on bottom) and side glass.

Are you making the bubbles hit just above the eggs and roll up?

Any descriptive device would be greatly appreciated. If I can get the suckers in the larvae tank, I have little to none die. I have rots for days. Hopefully by next lay I get this air technique down.

For the airstone, I use the rectangular ones. Like Jeff, I don't have the bubbles directly hitting the eggs, but I do have it turned up so that the water is at a rolling boil and obviously moving the eggs about. Night of the expected hatch I'll turn it down it bit, but still obviously agitating the eggs. Morning after hatch, the air gets reduced to a bare trickle.

I used to have the rigid airline by the eggs so the bubbles did not touch the eggs & all went well for over 5 years. Then I had a problem getting them to hatch & most of them turned white, fungus. Now I run high air & let it touch the eggs & my hatch rate is 98 -100 %. I even got a record batch of Ocellaris back in July, 932 in 1 spawn.

High air as in NO airstone, just rigid? And what is "high air"? Are we talking full blast, bubbles flying everywhere? Slow enough to count the bubbles per second?

And I'm assuming you are starting the bubbles under the eggs, and letting them hit the eggs and roll up?

Thanks for the advice guys!!!

Rigid airline, no airstone. Bubbles faster then you can count them & hitting some of the eggs.

If I hatch on day 8 at lights out (10 pm), should I pull that morning, afternoon, evening? Day 7 or before?

Does it matter?

I pulled on day 7 just in case and they hatched day 8. Its hard to believe with some air on them the eggs went south in 24 hours. Guess nature is hard to replicate.

If they hatching reliably on day 8, then I would pull them in the late afternoon. Though it could be done earlier if needed do to scheduling.
