Leonardo's Lagoon

Even with aquarium controllers its possible to fail. Controllers must have a set of contacts whether in a form of relay or sort, contacts can remain in the closed position therefore providing constant power to the source. I think that having two timers in series is more fail safe. If you have first timer programed to go off first and it does not then the second will. Generally contacts remain closed due to age of the contacts, whether they are pitted or carboned up.

ksed, I will make sure I will use two in series from now on. And maybe others should too! :) Timers are inexpensive and a disaster like mine is easy to prevent.

In the meantime I fixed the Return pump, and bought a backup. This won't happen to me again (at least, I will try)

I think you could pull out drive unit of 6201 by tools if the acid is not working, usually it would broken the drive unit, but you could buy new on from TUNZE, clean the motor block with acid, then make it run again.

I have repaired 3 TUNZE 6101 that the drive unit stick with motor block heavily. In this conditions, it is difficult for acid get into the space between drive unit and motor blok, so I screw a wood screws into drive unit and pull out it by a pliers clamped on the wood screws.
 
Leonardo - I remember at one point you were running a pH controller on your Kalk doser... did it not do it's job? or do you think the spike occurred after the last dose? i'm planning to run Kalk on my new system, but man, it does seem a little scary... and just to be clear, it was only T5's that stuck on -- no MH?
 
Welles; I tried to do it the way you described. I actually BROKE the screw trying to pull it out!

So I did it the messy way: With screwdriver and hammer -trying not to scratch or damage the motorblock shaft.-

This is how it looked:

After that I did a good rinse with HCl and polished the inside to make it clean and smooth again :)
I only have to purchase a new Drive unit + propeller now :)

tonyespinoza; You remember that correctly! I do have an auto shut off on the Kalkwasser reactor. But I think it just didn't shut down soon enough, and because of the extended photoperiod the pH kept on rising even after the Reactor stopped (in the morning).
Kalk is always dangerous to work with. That's why I use double safety: Dosing on a timer, not on the ATO. And a pH controller to shut it off. Seems like I need to rethink it and make it even more fail-safe.

Hello, You have it can be already spoken but I shall like knowing why don't you put sand?
It would allow you to have a support for bacteria and it would allow you to refleter the light and to increase of corals?

Please give us the picture of your tank...lol...

Thanks a lot...
Jo:D
 
Pics of my tank aren't so LOL right now...

I haven't had sand because I had success with the BB method in the past. Sand as a support for bacteria isn't really necessary and reflection of the light is also possible by reflective material underneath the tank.
I will aim for a more natural look when I do the rebuild, which is still scheduled in June.

Goods news! After a reduced photoperiod of a week, most corals are regaining back their zooxanthellae.
They are now adjusting to the normal lightcycle, I think this will take two more weeks.
In the meantime I will start to prepare and plan the move.

Because I don't want to experience this again I bought another ATI A5800 Return pump, so I have a backup now.
I also bought a new rotor for the Tunze Stream 6201 (wavebox pump), and it's working again! So after the move I can create a nice wave or some massive flow again :)

Just curious I guess, do you find that your doser is unable to keep up with the demands of your corals? Is that your need for the kalkwasser reactor, or do you use it to keep your PH up.. Sorry if you posted this earlier.

Glad to hear that everything is turning around..
 
LooseHip; I just dose the Kalkwasser to maintain a pH of 8.3 throughout the day.
The Balling-doser can dose up to 9999 ml. Balling solutions can also be stronger (double the salts) so that is almost a unlimited resource.

Thank you :)

Good news bout your reef recovery! :)

I just got a bunch of new frags, as well as the aragocrete essentials for my coral trays so I'll be starting my thread soon.

Glad to see you back in action!! :D

Keep up the great work and innovation! :thumbsup:
 
Leonardo, today I've been reading your thread from the beginning and nothing could make me feel so sad at the end. It was a bummer. I have learned a lot with you and you have inspired me for my new project. It's good to know that your lagoon is again on the track and is recovering now. Keep your great work.:thumbsup:
 
Leo, I just read about what happened. Sorry to hear of the loss :( I am sure you'll make a strong comeback. Good luck!
 
Machado, thank you. I follow your propagation system for a long time, love what you are doing! Can you tell me more about your new project? ;)

Kenny, thanks. Comeback is in the making :)

Maybe I have not understood what happened with your lighting control. Was the lighting directly connected to the timer or to a contactor? (I'm not sure if this is the right name of the device destined to open / close electric circuits, depending on the installed wattage, normally controlled by timers).

My new project is nothing special. I'm only planning to transform my mother colonies tank in a display tank. My tank has the same dimensions as yours.
 
Yes, the lights were directly connected to timers, that open/close the electric circuits. It failed, leaving the light on for two days.

Curious what you will do with the "same" tank in aspect to aquascaping etc.!
