Jelly Fish Nano Tank log P2: The Jellys have arrived!

After letting the tank cycle for about 5-6 week’s it was time order my Jellyfish. I had they overnight…however there was of course an issue with the shipper and they poor guys ended up taking an extra night.   I had been eagerly watching for the magic postal fairy for 2 days…..   then finally it happened.. they arrived!

The poor guys must have been frozen.. the bag water was 3-4 degrees when i opened it… i knew a very slow acclimation was key to their success…. for the next 5-6 hours the jellys sat in their shipping bag on my desk to slowly bring them up to room temperature..    Once the water was about 15C i slowly started to mix tank water into the shipping bag.. I moved a ladle full every 20-30 minutes to allow the moon jelly fish time to adjust

 

2 hours later they were in the tank… at first there wasn’t much moment… over the next 24h they slowly started to move and pulse as they adjusted to their new home.

Its now the morning of day 3: 2 of the jellys are happily pulsing around.  one of them had a tear in the bell which already looks to be healing up!  (these guys are amazing at repairing them selves! )   2/3 are good to go!

The last one is fully open and floating around.. i see a bit of movement in the oral arms.. but not pulsing as of yet.. hopefully soon.
Thats all for now.. check back soon for the next update.

Reefing Tip: Use a float valve – Save your floors and your marriage

I fill my 5g salt mixing bucket as well as my top-off container directly from my RODI unit…   I added a 50′ hose to the output so i can just bring it directly to the tank rather than hauling buckets around the house…

Now if you are like me.. and get distracted easily you have have ‘forgotten’ about your water running and come back to a damp floor.. yes i admit it happened 4-5 times now over the past year or two… so i finally wised up and purchased some float valves.

I installed a valve on the top off bucket and will do another on my 5g mixing bucket… This way if i ever forget the water on … the valve will kill flow and prevent another wet floor.

 

So if you haven’t already… do it!

 

Jelly Fish Nano Tank log

Earlier this summer I won a Jelly Fish Art nano cylinder tank…. and to my excitement it finally showed up!  I have always loved jelly fish and am excited to try them

The tank it self is esteticay pleasing. A tiny very quiet air pump provides gentle flow for the tank. The led in the Bottom will light up the jellyfish and make them glow.


I added the sponge from the rear chamber to my large reef tank to help seed it with bacteria. 

For some added filtration I think I’m going to add in some marine pure from the large tank.  Stay tuned for more updates!

New Apex Dos and Vodka Dosing

About a month ago I gor a fancy schmancy Apex DOS stepper dosing pump.. I was previously using a Jabeo dosser however, unplugged it once i got the calcium reactor going.   I decided to get back on weekly testing and stocked up on test kit refills..

 

For the first time since cycling my tank I decided to test nitrates and found it was much higher than i would have liked.  I used a red sea test kit..and was way off the charts for the low range test.. I then repeated the test in the “high range” mode and it read some where beteween 16 and 32…. So i decided it was time to try Vodka Dosing!

Shortly after I dug out the fancy apex dos that was hiding in the closet waiting to be unwrapped.  I chose the apex DOS as it deliver an extremely precise dose and was perfect for vodka dosing ( i actually got it for future automatic water changes but wont be implementing that until i move the tank closer to a water source.)

 

 

I figure my tank is around 120-130G with the sump.. subtracting sand and rock i settled on 100g to make calculations easy.   I’m following the chart below as a general guide on slowly increasing my dosage

Ill update this post as i go to keep you guys updated on how it goes!

Week 1: Day 1:  29/11/2016 I started on 0.5ml/day
Week 1: Day 3:  02/12/2016 Upped my dose to 1ml/day.

Jecod CP-40 hacking and DIY controller reverse engeneering

I just picked up a Jacod CP-40 gyre but was disappointing to see that the jabeo > apex connector does not work with this unit.. In efforts to figure out a way to work the signal and make my own i decided to do a little reverse engendering and see how it worked.. No keep in mind i’m still learning to use my oscilloscope.. this may be a bit of a leap for me.. but hey its a good time to learn!

DIY magnetic Kalk stirrer 

Magnetic stirrers are one of the simplest ways to build a DIY Kalk stirrer. I used an old reactor with a missing lid for the tube. You could also just use PVC or an acrylic tube.  For the used a hole saw and made a hole in the centre of a square of acrylic and bonded it to the tube. I sandwiches some rubber beteeeen a second price and drilled holes for nylon wing nuts   The rubber in the middle seals the lid
The base is a square of acrylic to hold a 120mm PC fan.  I did have to shave a few mm off the side of the fan to make it fit.  I glued a rare earth magnet to the centr of the fan and aligned it a few mm below the top of the frame to ensure it can spin freely

Inside the reactor be sure to put a piece of glass on the bottom to prevent the internal stir bar from wearing through the acrylic over time

   
    
   

DIY magnetic doser stand

Having a steel stand makes it a little hard to add on.. Well that is if you don’t use magnets!  I have been using strong magnets to mount all kinds of stuff inside my stand including my Jabeo doser 
I vent a price of acrylic by claiming it beteeeen 2 prices of wood and going over the edge with a heat Gun. I then used drywall plugs into the space between magnets in a magnetic strip bar and used screws to attach the two together 

The magnetic strip came from princess auto and was about $15. The acrylic I had laying around so all in all it was a pretty cheap project and looks great

 
 
   
    

Shallow Reef build Part 2

Something magical happneed… I got a call saying my tank was done!  After planning this upgrade for close to six months i was extatic to see my project coming to life.

A few buddies showed up to help with the move (thanks guys!).  It showed in a big wodden crate with the stand bolted to the top.. The tank it self was sealted tight like a mummy in a vault.. There must have been 600 nails on that crate…. Opening it was another challenage.  The first half to process involved hammers and pry bars trying to seperate the wood…. after slow progress i busted out the reciprocating saw and begun cutting the support posts… eventually we were in!

 

The tank was faily heavy but manageable.  I pre cut carpet to put under the stand which made it moveable (prior to filling).. this was great as it allowed me to tweak its position,  slide it out to put black vinyl on the back and make sure it was perfectly level

The tank it self is 3 sides starfire… it will eventually turn into a peninsula uptop the stairs but for the next year or two it will be down here against the wall.

With the tank in its temporary home I picked up some 3/4 plywood to build a sump stand and build my sump space.
