Salinity and Clams

[Barry N.]

I would like to hear what you are all keeping your salinity at and what do you measure it with?

Have 3 small 18 gallon tanks sent up so I can do some testing on different things such as feeding, pH swings and salinity. I have run a 60 day test with salinity swings to see how the clams react. Am NOT doing this with my holding tank.

Also your pH.

Barry,

We run our tank at ~1.0255 and 82F and use a refractometer calibrated with RO/DI water.

Here are the other numbers if you need them;

pH = 8.18-8.3
Alk = 3.46
Ca = 430-440

Have a good Holiday if we don't talk to you before then...

Doug,

I will think of you while I am laying on the beach in Aruba this coming week.

Your water is just about like mine.

pH 8.1 -8.25

alk 10.5 dKh

Ca. 440+

Salinity 1.025 with refractometer

Temp 78-80

I use a swing arm meter. I checked it with an old labortory hydrometer calibrated for 78F and a refractometer. I keep my S.G. at 1.024.
PH 8.1 - 8.3
Calcium 420 - 440 ppm
Alkalinity 3.0 - 3.5 meq/L

Regards,
Kevin

Hi Barry,

Both of my tanks run with:

PH - 8.1-8.3
SG - 1.026(35ppm)
Alk - 3.5 meg/l
Calc 420-440 ppm
SG measured with refractometer and pH pinpoint monitor calibrated every month.

I hope you and Sherry have a wonderful vacation,I think both of you need it If I don't get to talk to you sooner,have a great holidays.

[Barry N.]

Thanks for the input. We are working on somethings.

Gene, Check for hitch hicker

Yes we are looking forward to our trip and doing some diving in Aruba as well.

I keep my tank at 84-86 degree peak. I don't measure my pH. I have a little problem with my home made Ca reactor and have my Ca down to 300 lately. I am getting it up again. My Alkalinity is down to 2.5 the other day.
I use a refractometer to measure my salinity and keep it at 35 ppt. This is the only varible that I ma entirely happy with.

Thanks Barry

Salilnity is at 1.025.
Use a Tropic Marin float that was test and compared to a refractrometer.
Have not checked PH in 2 years.
Cal around 400
ALK around 2-3.5 Have hard time keeping it up.
Temp is at a steady 78.6 which is recently lowered from 80.1

Salinity is 1.026 with a ATC refractometer
Temp is 80.7 to 82.5 measured by Octopus
pH is 8.2 to 8.41 measured by Octopus

Alk is 3.2 meg/L
Calcium is 425ppm
