Puzzled over low hatching rate!

[MadMatt]

This is a solution that some breeders use that can thin the shell helping hatching. This solution does put an edge on the hatching but the problem may be that
the batch is just too weak, this mean the fry will start dieing off anyway.

So how do I remedy this?
1.thin the egg shell?
2. Increase the strength of the batch?

How many spawns did you have this hatching problem?

How many spawns did you have this hatching problem?

Cliff

All 5 of my pairs.
4 pair are very active, they spawn all the time, 3 of them continually spawn.
It's the same failure with all.
I'm implementing many of the recommendations on this thread.
What are your suggestions?

Very much appreciated!

Thanks,

When ever I've had problems like this in the past. Here is what I do.


After a couple of hours after the Discus spawn. I hatch the eggs in a separate container with pure RO or distilled water with a few drops of mb.

If you get a good hatch rate you can more or less eliminate the water problem.

Try this

Ph 7.2
TDS 50
24hr aged water and add Seachem Safe to neutralize Ammonia, nitrite, narrate, and heavy metals.
Blend tap 30% and RO 80%
82F degree
50% WC daily and wipe the tank twice a week.
WC is done with aged heated water at 80F degrees. If you add colder water it would encourage them to spawn that's why I keep 80F in a separate barrel.

Try breed them twice a month only so they could recuperate. I put all my adult breeder in one big tank and they get 100% water change daily and once they ready to breed I separate the pair to their own tank. I don't have any bonded pair whoever is ready I just pick the male and female. I like to mix my breeder

Sorry Blend tap 30% and RO 70%

Looks like the problem is now share with the other breeding pairs, probably a water problem. I recommend Rick Miles suggestion but buy some new R/O water
instead of using your R/O system.

My RO system is only a few months old, seven stage, my TDS ppm is 12-16 from the RO filter.
Is this no good?
I think maybe a lower TDS like 25-35 might make a difference.
Thanks for all the suggestions everyone it's really helped.
I will keep all you guys posted!
