Hi all,
I got 2 batches within an hr 2 days ago, I guess about a thousands.... today I did a first water change. Since it is winter here so what I did is I use a bucket to make the new water yesterday, then before I do the water change I use heater to match the temperature. The salinity in the hatching container was 1.025 and I set the water is around 1.022 (
iirc).... I use the dripping method which around 3 drops / sec. After I did water change I guess I lost not a small amount of
larvae and they are at the bottom...
The salt I use is Seachem, and it seems giving trouble with my corals as well (which I suspect). What happened was I have some hardy SPS in my other tank and when I was away I asked my sis to look after. Of course turns out that PO4 is ~ 2.5 ppm however they are still survive. After I back from the trip I did water change using Aquavitro salt and the corals recover very soon. Those receeded area were regrown within a month. Then I ran out of salt and I got this bucket of Seachem.
I got a spare tank so I decided moved the corals to this tank and make it as SPS dedicated. I did the following same procedure last year after I physically broke my tank and I got no SPS loses: I use the tank water to put it in the new tank, added some new water on both old and new tank. The water temperature matched. Then I moved my SPSs to the new tank.
My colleague and I got 2 birdnests from the same shop, both of us using Seachem salt but different batch. Both birdnest in our tank got RTN. We changed the parms, Ca, Mg, KH, PH...etc are in the good condition. Then I got a new bucket of salt which is RedSea since my
LFS doesnt have Aquavitro at this moment. I did water change and the birdnest (along with other acro) stopped RTN, the clam reopening. However my colleague one is totally RTN-ed (I gave him some of RedSea salt but not sure if it was too bad it is completed RTN).
Just wonder if it is the salt problem? I used to use Aquavitro when I was trying to breed last year and seems ok. My last batch of peppermint (2 months ago) the last one survive for a month only...
Hmmm I dont know.. Im lost
