Could somebody help me with reducing SG?

Post by Mech »

So in my other thread i posted that my shrimp arrived with a SG of 1.020, i measured this with my refractometer. I matched my tank water to the bag my shrimp came in and they are all doing well and are becoming a brighter red :D

This however is pretty high SG for these guys from what i have read? should i bring the SG down to 1.016 or so? From what ive read some keep theirs at 1.018 - 1.020 for better breeding however this seems to contradict other bits of info i have read.

I'm not keeping these guys just to breed, that's a bonus but i want them to be healthy so what should i do? and if i am going to reduce the salt what is the best way to do so? I understand its better to do it over a long period but what technique should i use? just remove a pint a week and add a pint of RO by dripping it in?

thanks for looking.

I kept mine at 1.015. No breeding yet though. But they look happy and healthy. :)

When I matched my water to the bag my shrimp that I bought, my water must of been cold when I measured it as it dropped from 1.020 to 1.018 after a few days.

I'm glad you're shrimp are enjoying the salty side, as are mine :)

Mech there is a site I believed called salty zoo that has salinity conversions and how to increase/decrease safely from one salinity to another. Multistep process over a period of several weeks to hit a target salinity. I used this site when I was fooling around with salinity. No breeding of course. In habitat salinity would change from rainy season to dry season. The change I thought would induce breeding. All it did was delayed breeding. Once I settled the salinity to 1.012/1.013 and left things alone breeding proceeded. Hopes this helps.

That info is incorrect. There is no better (or worse even?) breeding at that salinity. All my tanks are way below that salinity (usually around 1.008 to 1.012 SG) and some tanks have over 150 larvae floating around. I can't imagine breeding getting any better than that. :-D I wouldn't worry too much about salinity.

Thanks for the information, I'm gradually brining it down should I be aiming for 1.012?

No need. Just leave it the way it is.
