Alan Posted December 30, 2004 Report Share Posted December 30, 2004 I always use sea water, untreated. What you appear to be missing is aeration. You have to have it on quite well and turn it off when you want to harvest the BBS. Alan 104 Quote Link to comment Share on other sites More sharing options...
absynthe Posted December 30, 2004 Report Share Posted December 30, 2004 I had aeration, an airstone 3/4 of the way down the bottle. I turned it down an brought it 1/4 of the way down when they began to hatch. cool...off to the beach then... Quote Link to comment Share on other sites More sharing options...
Alan Posted December 30, 2004 Report Share Posted December 30, 2004 absynthe said;:- No I wasnt looking at the shells...they were floating. The BS hatched, swam around like mad for a while in big swarms at the bottom. I went to the supermarket and by the time I got back they were lifeless at the bottom, no movement! With the above information. NO WAY was there aeration. Not enuff if any. Shells floating. They should be tumbling thru the mix. swarms at the bottom Same as above lifeless on the bottom Same as above again. Wind the air up or get a new diaphragm for the pump.

absynthe Posted December 31, 2004 Report Share Posted December 31, 2004 I had turned it down by that stage as they had hatched...there was slight circulation of the water but not strong enough to prevent the BS from moving towards the bottom.

Alan Posted December 31, 2004 Report Share Posted December 31, 2004 As you may have gathered by now. The aeration should have been kept up till you were ready for harvesting. Bad luck. Better luck next time. Alan 104 Quote Link to comment Share on other sites More sharing options...
