Dnoob's 395g reef from Finland

Beautiful tank. You have some amazing colonies.

Would you ever go back to gyres? Or are the QP-16's much better?

 

[Dnoob]

Gyres were so loud. They moved the water but I do not want to hear it to other side of the house QP-16 is quiet and move the water nicely. Ofcourse the quality difference can be seen but I can buy 4 of them in the same price as gyres. The flow pattern is better adjustable when there are 4 powerheads.

 

[Dnoob]

And there she blows! For some reason my clam started to spawn. Thats what they do but when the clam is bigger than my head that will change the water to "milk" really fast

 

[Janci]

Wow. Looks amazing.

 

[Dnoob]

Lots of happy corals after having that amount of food in the water

[Janci]

They gather and cruise like sharks

 

[Dnoob]

I added 10kg of sand to tank and changed the flow pattern. Now the sand stays, but the water is still moving nicely. It's not easy to have strong current without the sandstorm

I have suffered low PH so I bought an ATI EX 4 Co2 scrubber. Normal value was between 7.79 - 7.9 during the day and night. ATI has a quite big grain media and this will help the airflow trough the scrubber to skimmer. What I read from the internet it should increase the PH value easily to 8 - 8.4.

I ordered a calcium reactor. The amount of balling is so high that I have to fill the containers all the time. I choose Deltec PF601s model and it will be controlled by Profilux 4 and KH director. Director will keep the dKH steady by controlling the PH value inside the reactor. Let's see how it works. It could be a disaster or great success

 

[Janci]

How is the ATI CO2 scrubber doing?
Did pH raise?

 

[Dnoob]

Not so much as I expected. Only 0.2 - 0.3

I love this reactor plan.
All German engineering. You are taking risks. LOL

 

[Dnoob]

And here we go. Still waiting Kamoer FX STP and then the packet is ready to use.

[Janci]

Great shots.
The coral will love the calcium reactor

 

[Dnoob]

Test drive ongoing. Today I move it to production and throw the balling to backyard. Co2 solenoid is controlled by Profilux 4 based on PH measurement.

 

[Dnoob]

It works like a dream. I'm driving the reactor 6.15 PH and the hysteresis is 0.1 so the PH window is 6.15-6.25. I'm going to go low as 6.00 if needed and narrow the window to 0.05 PH. Dastaco2 pure calpro media should be used 6.0 PH and that gives 60-70dKH. I don't undestand why most of the people here in forum seems to use 6.5-6.8 PH level? dKH of the tank is 8.7 and I'm going to keep it about this level. Flow of the feeding pump is 33ml/min.

I got all the information and controlled outputs in the Profilux 4. It helps a lot to find and keep the optimal PH and water flow. KH Director gives the dKH every 6 hours so I know what is happening in the tank.

 

[Janci]

Great setup with this German combination.
Did you find the sweet spot already to maintain dKH?
