woot woot!

My first piece of Deltec equipment arrived today. I got an awesome deal on a used kalk stirrer. It's probably going to be a little bit before i get to hook it up because i need to order a few things like a float switch and a solenoid valve. Hopefully, it will help me get my ph up past 8.0

I thought you were talking about the cubs....

Now i am thinking of a good way to hook this up. Here's what i am thinking. I'm going to have my RODI run to a float valve installed in a 5 gallon bucket or something similar, from there i will have an aqua lifter going to the stirrer. The aqua lifter will be connected to a float switch mounted in the sump so when the water level gets low it turns on the aqua lifter, the aqua lifter will then push water through the stirrer into the tank.

Sound like a good plan? I would like to add a solenoid in the line between the reactor and the bucket for added safety, but i think for now i am going to keep it simple and inexpensive.

If you're going to take this route, I would use something bigger than a 5 gallon bucket for the RO storage and not use a float switch from your RO unit.

Good deal Jeremy.

I agree with Slovan, I would not use a float switch. Just time it out with your Aquacontroller. Thats how mine is running, it reduces the risk of something going wrong should the float valve fail. I would also go along with using a larger container for your RO/DI water.

Ok so new plan. Going to use a 20 gallon rubbermaid tub with the float VALVE inside to keep it full. I know you guys say not to use them but i have been using one on my sump forever w/o any problems. I just got an electric solenoid so i will have it setup so that water can only run to the tub for 3 hours a day. That way if the float valve ever does stick the flood will be minimal. Then i have a aqualifter sitting on top of the tub controlled by my ACII. The aqualifter will pump water from the rubbermaid to the stirrer. I really have no idea what my evaporation rate is so i am going to just try tweaking this program until the water level is maintained. For now i am going to let the pump run 1 minute every 4 hours.

The kalk stirrer is programmed to stir for 15 minutes every 4 hours.

What do you guys think? Sound safe enough?

I think its gonna take some time to get the program adjusted right but it should work pretty well after that.

 

[Coralfreak]

The float valve in the container should be fine, just keep an eye on it.

This is a Deltec stirrer right? It should run 24/7, don't turn it off.

1 min every 4 hours probably wont even be close, just a guess though. I use the OSC command:

OSC 004/011 ON/OFF Then DOS ON

 

[waverz]

Yeah its deltec, i guess i just assumed you didn't want it to run all the time. I guess it makes it a little easier to program them.

I'll bump up my dosage and see what happens. I don't have the slightest idea on how much i lose a day. I guess it wouldntt be too hard to figure out. I could just not top-off for 24 hours and measue how much i put back in until its full, but that sounds like to much work. I'll just bump up my dosing program and see what happens.

So you dose for 4 minutes every 11 minutes? I'll start with that and see what happens.

 

[Coralfreak]

Yep, only runs that program for about 17 hours a day, so you may need to adjust it some for a 24hr run time. May want to drop the on time down a little and increase the off time, then just keep an eye on it. Does the AC2 have the "IF TIMER" command? I don't think that it does, otherwise I could give you an even better setup.

 

[waverz]

I dont think the ACII's have that cmd but i will look into it.

 

[waverz]

ACII's don't support If Timer....shoulda saved up for the ACIII.

I believe aqualifters push roughly 3gph ( I could be wrong though).

I would guess your evaporation is somewhere between 1.25-2.5 gallons/day

4on/11off 24hrs/7 would be approximately 384 minutes of dosing a day. 384/60= 6.4hrs dosing/day 6.4*3gph =19.2gallons/day

I doubt the Aqualifter would really push that much water thru a kalk reactor, so that is probably a high figure. However, you might want to do a little testing/measuring before you put it into full effect.

 

[waverz]

I am running it at 2 minutes every 4 hours, but i think i will shut it off for 24 hours and actually figure out how much i lose to evaporation and then figure from there.
