Methylene blue dose for egg protection

Postby Fred Goodall » Sat Jan 07, 2006 6:54 am

Hello All :welcome: this is Methylene blue dosage for protection of discus eggs:

If the male fertilises all the eggs and all of them are fertile and living, there is no need for MB because there is no dead cell for the fungus to grow on.

The common scenario is that a certain percentage of eggs are bound to be unfertilised....and if they are laid very close to each other, fungus that grow on unfertilised and dead cell will also encase and suffocate the rest of the fertilised eggs and growing fetus. We must assume that as proffesional breeders and don't take chances and don't give way to failure.

The dose is 100mm ( 4 inches ) visibility. 80mm ( 3 1/4 inches ) visibility is quite acceptable.

To measure,

3 hours after spawning, add MB, stir and wait for 5 minutes for the water to become homogeneous or uniform throughout.

Using a ruler, put a white tape on the tip.

Submerse the ruler from the surface in position way back of the tank.

Strong light or aquarium light should be turned off.

Dip the ruler till you reach the 80 ( 3 1/4 inches ) or 100mm ( 4 inches )mark.

If you can still see the tip, add more MB. Repeat as above till you can hardly see the white tip. That will be the concentration and is effective against the most stubborn fungus.


Take care,
Andrew

:welcome: Hi Fred, after the eggs have hatched, do we need to remove the MB from the water or does it desolve by itself :question:

Thanks and have a nice day :wink:

It is good practise to remove 50% within 10 hours before hatch.

But if you missed it, It is O.K. You can dilute it after the eggs hatched immediately or withing the next 2 days.

On a system or large aquarium a good tip is to place an acrylic tube over the spawning pot, the top of which must be above the water level, thus sealing the area. The MB can then be added to the inner bit and is really concentrated where its needed, the parents can still see the eggs and water temperature is maintained. When the tube is removed the MB is instantly diluted into the water column.

This method works best when the spawing cone has a hole in the top - an air line and small stone inserted, and when the tube is in place gentle airation is applied.

One question though: In my experience MB degrades if stored long. I have however not found any "use before" dates on my bottles. Any way to verify the quality of the MB I have in stock?

I am asking as one of my breeding pairs spawn in 350 uS water, and even adding MB to Andrew's dosage will yield less than 10% larvaes - rest is fungus affected. 95% + were fertilized, and I have removed the few eggs that were not (using a pin)..

Tom

Hi Tom,

You are right. MB does not have expiry date. If stored properly in just normal, non-damp condition, it can be kept for years and will still be effective. It will not degrade....10 years?...no problem.

If you only find 10 wrigglers...literally it means two things...

1) Your male did fertilised the eggs but the milt is not primed and healthy...thus most eggs did not form into healthy fetus. Use pro-more...sure helps. Bear in mind MB is needed.

2) Your male did not fertilise all the eggs.

Take care,
Andrew :angel:

Thanks Andrew, cleared that up.

Beleive me! I have just started using Pro-More and I expect much better results after this.

Just wondering if my 350 uS might be to high; haven't seen much improvement from the same pair i sub 200 though.

Tom

Hey Tom and Tony,

Though I do not advise as you all are not me....I have been eating it everyday...one tablespoon....my sp--m count increases. And whenever I start to have flu, I will double the dose...twice a day...and my flu stops in 2 days. I mix it in my morning coffee..exotic taste..a little salty..right?

This is one of the many reasons and studies why I can affirm that not only is the pro-more guarantee to help in success spawning, if you continue to feed during nursing period, even 400 wrigglers pricking on the parents will not cause them (the parents) to fall sick because when the pro-more is not used in sperm (milt) production or egg production, it will help the fish to repair tissue and fight against infection and repair wounds caused by injuries and secondary infestation/ infection.

:thumbsup:

Take care,
