my breeding discus tanks water are so weird

[vicdiscus]

I was posting here for parameter water for ideal for breeding.

Today I did do water change and fill up stright out by tap water. My 4 proven breeding pairs are ready to spawn.

The tap water stright out , The water test result is Conductivity reads 44µS TDS reads 28 ppm Ph 6.8

So I fill up water to my 4 breeding pairs discus tanks. All breeding tanks temp are 83.

Tank 1 TDS 49 , 84µS Ph 6.6 Ammonia, Nitrate, nitire are 0

Tank 2 TDS 76 , 131µS Ph 6.8 Ammonia, Nitrate, nitire are 0

Tank 3 TDS 76 , 115µS Ph 6.6 Ammonia, Nitrate, nitire are 0

Tank 4 TDS 48 , 54µS Ph 6.8 Ammonia, Nitrate, nitire are 0

I think tank 2 and 3 might be successful spawn. I hope the eggs will be good.

any suggestion and feedback?

Thanks

Hey Duncan,

Don't understand why your nitrate is 0????

Hey Ralph,

I use API Nitrate test kit. the test reads 0 ...the water is good quality..

what is your water hardness?

[vicdiscus]

what is your water hardness?

That is a good question. I do not have hardness test kit as API GH/KH

What I thought TDS and Conductivity for hardness water test.

For Conductivity 1 DH as GH and KH ?

[vicdiscus]

CONVERSION TO OTHER SCALES OF HARDNESS
33 microSiemens = 17.9ppm
33microSiemens = 1dH (German ° hardness)
1dH = 17.9ppm

***Therefore the mathematical formula for a conversion to ppm is: Take the reading on the display and divide it by 33, then take the result and multiply it by 17.9

[vicdiscus]

Tank 1 84µS = 2.5 GH

Tank 2 131µS = 4.0 GH

Tank 3 115µS = 3.5 GH

Tank 4 54µS = 1.6 GH

[Skip]

TDS is not water hardness.. just a little FYI for ya..

[Second Hand Pat]

Duncan,

There is a API GH/KH test.

I will buy API GH/KH test kit. What I thought the Conductivity for hardness water test.

Warlock, Thank you for your tip info. is it TDS 100 or less are ok for discus's spawning and good rate eggs hatching?

[Skip]

in most cases..

the water needs to be soft in order for the eggs to hatch.. then you can add tap water again and be just fine..

tds don't matter, but water changes does lower it

Not so sure about that Skip. I had to lower my TDS to 80 to get wigglers from the Cuipeua X females. They were eating the eggs at the higher TDS.

let me rephrase.. TDS is NOT the only indicator for water softness :)

[vicdiscus]

All right... the location fish stores do not carry API GH/ KH... damn it..

I would like to know what is measure for ideal for discus breeding?

Thank you

Duncan

True, kinda. You can have a higher TDS and still have relatively soft water. However, the inverese is not true. You cannot have a very low TDS and have hard water. So, for breeding purposes, if you have a low TDS, you should be good to go.

[vicdiscus]

Thank you for your helpful and info. and Let 's see what happend the breeding pair.

The tank 2 for the Red Checkerboard Pigeon blood just spawned yesterday. Now it is pass 24 hours.. Wait to see tomorrow evening if the eggs turned to darker.

Hey Ralph,

I use API Nitrate test kit. the test reads 0 ...the water is good quality..

Duncan

I still think your nitrate test result is wrong. You should get a nitrate reading 5 to 20ppm once your tank is cycled and only your Ammonia, Nitrite should read zero.

...Ralph

[vicdiscus]

Hey Ralph, you was right... and you are right.

I was wrong test for nitrite for nitrate..

i have API test for nitrate.

The result is

1 Tank 20 ppm nitrate.

2 tank 40 ppm nitrate

3 tank 40 ppm nitrate

4 tank 10 ppm nitrate

Do you think nitrate too high affect the eggs turn to bad?

Duncan

[Altum Nut]

Duncan,

Tanks 2 and 3 are high. Your goal should be between 5 -20ppm. Are you doing regular w/c's and how much%...?
Water quality is always important regardless.
you can try to cut back on the amount of food and make sure you vacuum any uneaten food.

Ralph,

Tank 2, Tank 3 and Tank 4 all eggs batch are not good! I am getting so frusrated..

The parents are great to eat and no left over food. I fed them Frozen Hikari Bloodworms, live White worm, CBW, and mysis shrimps.

I do water change every 3 rd day at 50% and I fill up new tap water from stright tap water..

Plan A I will set up a tank for aging water.

Plan B I have an idea I would do the same way as Asian discus breeder's systems.
