Realize that you are running the Kalk reactor for it's effects on pH in addition to Ca, but since there is a Ca component, have you measured the Ca with the different stirring strategies (or is there a direct collation between ph and Ca).

The clear liquid at the top of the reactor is Calcium Hydroxide. An over-simplified way of thinking about this is that the Calcium represents the Calcium part, and the Hydroxide represents the Alkalinity part. So...yes, a measurement of the liquid's pH is representative of Ca and Alkalinity potential of the liquid, in this case.

My skimmer filled up again last night. For some reason, every now and then the skimmer goes nuts and fills the collection cup. Once the cup is full, the skimmer burps and spits, spattering everywhere...including on my touch screen. (one time, it actually told the controller to lock the CO2 supply on. It drove my Ca reactor down to pH of 5.8 before I noticed!)

So, I've had enough. I rigged up a float switch, and connected one of the three skimmer pumps to the Aquatronica contoller. The float switch sits in the skimmer colletion cup, if the fluid in the collection cup rises, it shuts down the skimmer. Should have done that months ago!


Here's a screen shot of the controller screen. On the right hand side you can see the various inputs including "skimmer level - OK". The skimmer is now assigned to plug "H". The "L" on that plug indicates that this plug is contolled by a level sensor. The blue outline means that the plug is currently "on".

That's your Aquatronica lesson for today...

Two questions...is your float valve just floating in the cup and where did you get the float valve?

wow a skimmer that can use a touch screen. that thing is evil

I know why your skimmer is over flow like that ...........................

ITS A ASM skimmer

BUY A ATI BM 250 GUY

It is easy to poke fun at ASM, because they really are built poorly....but this G6 works very well and I would continue to recommend it as high value for the buck. I don't think the boil-overs are related to skimmer design or construction quality, in this case.

Ha..ha..new skimmer...Yes, but I don't think an ATI MB 250 is large enough...plus it won't keep itself clean. I have my eyes on a larger prize...(now, lets hope the CDN $ stays high a bit longer...)

It is pretty much just hanging in there. I haven't tested it by filling the skimmer cup yet, but I'm pretty sure it will work. The float is standard Aquatronica equipment. The AQT comes with a float switch in the standard package. I had not been using it until now.

unbelievable tank probably the best i've ever seen outside an aquarium park how much are you in for if you don't mind me asking? does the wife approve?

Brad-

I (finally) finished your tank thread. All I can say is "WOW". You are an inspiration. One day...

Thanks again for all your help over at RC.

Cheers,

Los
