PROBE CALIBRATION OUT ?

I refer to the salinity variation experienced as per my post below.

I have since re-calibrated the salinity probe and whilst the readings are closer to what I would expect it is still little out of whack.

I will double check with a spare hydrometer that I know is 99.9% accurate.

Happy reefing !

UPDATE !!

I upgraded the firmware on my Profilux II a while ago and battled to reconnect via the RS232.
This resulted in me being unable to use old sensor calibration data and had to do all afresh.
I guess in the process the maximum on time of the auto top-up was shortened to a few seconds.
This meant that the top-off timed out before all evaporation could be replaced.
Due to a busy schedule I only picked up on it a number of days later when the return pump started sucking in air.

I immediately made the required corrections and slowly added fresh water to correct sump level.

All went relatively well - but noticed that salinity sits at 30 instead of 50 . I am a bit perplexed about this. Could not figure out how this might have happened.

CLAM LOSS !!!

I am sad to report the loss of my squamosa clam.

I have had this specimen with me for a number of years and early last week was still well.

I have been battling phosphate in my tank and use phosguard(Seachem) in a fluidized container.

I am unsure as to whether this brought the sudden demise on......................

I will miss it :-(

A FEW MORE PICS ;-)

THE MOVE IS ON !

Funny in a way I guess ;-)

But as I eventually get the picture up - I also need to say that the house has been sold.

This means that within the next month or so - thoughts of re-locating the tank will start filling my mind.

I do not look forward to it - is always a lot of hard back breaking work.

And there is always the risk that something might go wrong.

Also the tank is so damn heavy and a bugger to move due to it's shape . It must be turned on it side to go through any doors.

Wet hands and a slippery glass wheel is essentially what we are dealing with.

I have done this a few times now - so will add some of my tips and experiences here.

Hope somebody can find some use from it.

Happy reefing until next we meet.

FINALLY ! A PIC OF MY CIRCULAR TANK ;-)

LOOKS LIKE THE TANK MIGHT HAVE TO MOVE

We have put our house up for sale. ;-) I have been wanting to re-aquascape , but based on this have decided to let things be.

The tank is due for a make-over but will rather do it once we have settled in our new abode. Will be a few months still,but just makes more sense.
I am still fighting the scourge of Rodactis in the tank and will probably end up scrubbing all of it off the rock before placing it back in the tank.

Happy Reefing

Till we meet again !

HIDE AND GO SEEK OCTOPUS

Sydney - Australian scientists have discovered an octopus species that carries around coconut shells to hide in when threatened - behaviour the researchers said was the first example of sophisticated tool use in an invertebrate.



Rest of story here

A SHORT BREAK

We will be taking a break from trading for a while - so will not be able to take any calls. Please still feel free to look around ;-)

Be back soon.
