Yup if conditions are right ie. high Kh & Ca, your tank walls will be covered with Coralines.

Sure will test out this evening. In order to be more accurate, I will test it for 1 week and collate the result to be posted here. In terms of maintanence, I guess, I will just do some form of cleaning to the exterior and top-up kalk whenever necessary.

It is true that the Kalk Reactor will not be suitable for some tank especially those with chiller or low evaporation rate or have high Calcium demands such as SPS/Clams tank. I myself started by dosing Kalk after lights of and after several months of measuring, noticed that the amount of Kalk I need to top up inorder to maintain params is almost equal to the amount of water evaporated. So i gather that the Kalk Reactor will be suitable for me. And after having it the pass few days, I must say that my params are still alright although not so constant as per accurately measuring the depleted and topping up exactly the same amount.

Just did a check on some of the pumps commonly used for Kalk Reactor and below are the electrical consumptions: Eheim 1250 - 28w Oceanrunner 1200 - 25w Quiet One 1200 - 25.5w Magnetic Stirrer - 3w

As for the measurement, I can do a calcium test this weekend. But I feel that it will not be any difference from mixing a kalk solution, waiting for it to settle and taking test from the clear solution. As such, whatever the reading is, it is due to the Kalkwasser rather than the reactor right? Correct me if I am wrong.

I dun quite understand your question. Do you want me to measure the Calcium level from the output of the Reactor? I have not done so thus no info at the moment. But is is that important? Could you enlighten me with the reason?

Price-wise, I am not able to compare cuz currently I only know Coral Labs carries a Kalk Reactor with Magnetic Stirrer. However, if you are talking about Price as compared to the benefits and the quality of the product - I am honestly says that it far exceeds my expectations.

The only maintenance is to top up Kalk when the residue get lesser and lesser.

Also, I forgot to add, the consumption of electricity is surprisingly low. I was told that it only consume 3w only! Now which external pump can beat that!

My final verdict is that I am very satisfied with both the Tubby and the Kalk Reactor that Coral Labs carries and have also heard tons of great feedbacks on their other products such as FR and even Chiller! I would like to end by borrowing their tagline, "For Excellence Corralines Growth and Prosphate Free Water". Here is my recent growth (Corallines).

Now comes the best part of this Reactor! Noticed when the reactor is in action, the cloudy kalk solution will not rise beyond 3/4 height of the Reactor - this will ensure that only the clear solution is dose into the tank rather than the milky solution which will cause ionic imbalance. Also, another "killer application" Coral Labs has installed is a "built-in" timer! No to waste $20 to get a external timer and program it to turn on & off! I heard from the people in Coral Labs that they have program it to run 1.5 mins per hour and from my observation, it is sufficient to ensure that the kalk is thoroughly mixed. Another point to note is that there is another manual switch (The red botton) that offers the option to start the stirrer as and when I wish! (talk about control)

Aiyah, it is because too much nuitrients in your tank. Try to reduce feeding, check on the Skimmer (Ensure that you clean up the collection cup), improve water flow. Now fasting for AT.

Here's the answer to backflow of Kalk into the freshwater tub.

Here's the top view of the reactor.

Here is the reactor when it is on "Standby" mode, noticed the kalk settling at the bottom of the reactor. I have put in 4 teaspoon of Kalkwasser. Also, noticed the view of the solution inside the Reactor that Acrylics offers VS PVC.

Ever since I given up of Seahorses and Ventured into Reef Tank, I have always struggled with maintaining constant parameters in order for my livestocks to thrives. The very first equipemt I invested to maintain the params was a Tubby. When I got it, I was very impressed by the quality of its finishing and also the inner components which was told by CM - is manufactured for military use. I have since used the tubby for 1 years plus and never have the tubby failed me! There was only once where by my overflow stucked and causes the float switch to be submerge for a long period resulting a failure to one float switch. But it was quickly diagnosed and replaced by CM within the week. With this confidence in thisCoral Labs product, I started to save up for their Lastest Kalk Reactor. I am very fortunate to be the 3rd person to received the very First Magnetic Stirrer in Singapore! Upon receiveing, the following thoughts came to my mind: Clean-cut, Well thought and Solid contruction. Herewith is the picture of the reactor next to my fresh water tub.

Calling you soon.

Will do. Thanks again.

That's why it is always good to seek your advise! Sigh.... me always think one way only - one tracked mind. No choice lah, just have to pray loh....... By the way, bro, do you have any contacts you can reccomened for the thread I have posted at the DIY forum?

I thought since the two tangs has been in the QT tank for 7 weeks + they would not welcome another tang thus adding AT into the QT tank will cause some form of bullying, don't you think so bro?

Hi reefers, I currently have a 3 footer with two 20mm pvc pipes drilled and fixed into the tank. One to function as a return and the other as a overflow. However, I realized that one 20mm pvc pipes alone cannot gives me the flow rate I wanted. After considering the different options, I have decided on the below; 1) Convert both PVC pipes into overflow. Converging both pipes into one connected to one bigger PVC pipe with ball valve to control flow. 2) Create new PVC pipes line from return pump to display tank - going over the tank glass and spliting into two direction. 3) Customized new tank hood to accomodate new pippings and existing stuffs such as 2 x t5s, 1 x mh and 4 x DC fans. Can anyone here help me with this? Or reccomend me someone or company that is doing the above? Hope to do it ASAP.

Aiyah, add into display liao. Anyway, I don't think I can afford to add AT into the QT tank as I already have 1 x Purple tang and 1 x Hippo tang inside for 7 weeks + liao. But adding the AT in, I will only be sending AT into a slaugtering house. Hope all will be well. Wish me luck.

Thanks bro, will skip FWD. But my diaplay is not FOWLR, it is without fishes as all fishes has been remove for Hypo at QT tank. My Display contains inverts, lps & sps, so my plan is if ich appears, I will fish out AT for Hypo.

Aiyoh, look at their display tank and you have the answer liao mah. If those people after looking at their display and still think that it looks nice then they can follow their advice loh.

Sorry bros, should be 20kk. Already inform Mod to change title.
