LaCl Reactor

[Heliman]

A quick question about Seaclear...

We dont get this stuff in Aus, our local equivalent product is sold at a concentration of 150 gm/litre of La Cl (15%)

When you say Seaclear is 66% diluted , do you mean 66 gm/litre La Cl or is it 66% water and 34% LaCl ??...I am just trying to get my dose rates aligned with yours.

66% water to 34% LaCl3, but yes.

I use the tubing to get the water and LC blend down to the bottom of the reaction chamber, so I'd say yes. I dont know what size the tubing was. I just found a piece laying around that fit over the little lip that is inside the reactor. You will have to experiment with it.

If you dont do a 1.1 ml doser, you will have to adjust your total water volume accordingly. I can only go off what I have had experience in being successful. So far, success has been from dosing a total of 2.5-5ml an hour and spread out over VERY small doses. The lager the dosage, the more water you will need to dilute with. You will need to figure out your own dosage rate in order to keep it safe.

Questions: Do I need to have a tube running the solution into the bottom of the reaction chamber?

What size tubing are you using?

Where does the check valve go?

Is it absolutely necessary to use the doser (1.1ml)?

I'm sure I will have more questions...sorry! Thanks!

Could you post your code? I am curious to see if my brs doser drops liquid at 15 seconds.

Present rate is about 3.5ml per hour. I dose for 15 seconds at a time with a 1.1 mm doser. I will post up my apex code tomorrow, but you get the idea.

Insomniac posted the code I'm using on page 4 of this thread. So for my reactor setup is working great with no clouding or adverse effects. I use an apex to control my BRS doser.

 

[bmanzie]

THanks I see the code.
I was hoping for a little more explanation on what is going on in the code.
If I break 3:30 + :15 down into the hour, I get 60/3:45 which should give the how many times it is dosing. If I did that write, it is dosing about 17 times an hour.
I wanted to see how much is dosing both at the 15 sec level and the hour lever in case I want to adjust the dosage. I can't seem to figure that part out.
insomniac2k2, could you please give me some insight on the math you used?
Thanks a bunch.

 

[bmanzie]

Good morning, I thought I would try again and ask for help with the math.

 

[finrod2]

I'll give it a try:
I have set my apex to turn my BRS doser on every 3.5 mins for 15 secs. That equates to 411 doses per day x 15 secs or 102minutes

My BRS doser is 1.1ML per minute which means I does 113ML/Day of solution

My solution is 1 gal (3786ML) of RODI water plus 20ML of Seaclear CR, that is a .00528 solution so at 113ml/day is doses .6ml of seaclear per day. I am lowering my PO4 very slowly and I may increase the frequence of my dosing but I am trying to be careful so no free LACL gets into my system. Hope that helps.

So if the doser delivers 1.1ml a minute,15 sec would be a quarter of that (.275). Understood
3.5 minutes + 15 secs = 411 doses per day. How? I take 3.5 + 15=3.75 and devide 60 buy that. 384 ml per 24 hour period is what I am getting. What am I doing wrong?

I'm getting 384 doses per day with a total dose of 105.6ml

60min/hr x 24hr = 1440min/ 3.75 = 384 doses x .275ml per dose = 105.6ml dosed per day.


I believe the poster above had his 15 second run time included in the 3.5 minute timeframe.

60min/hr x 24hr = 1440min/ 3.5 = 411 doses x .275ml per dose = 113ml dosed per day.

 

[finrod2]

Yes I should have included 3:30 + :15 = 3:45 or 384 doses per day

 

[insomniac2k2]

Yep, when i did my first equation on this, I neglected to subtract the 15 second run time. Which projected me near 5ml an hour. The true ml per hour is like Jerpa listed here. My "dosage" rate is near 4.4ml per hour.

My maintenance dose is a bit less. I had it down to somewhere near 3.5ml an hour, but my numbers started to rise. So i went back to my "dosage" rate.

Ironically, it seems that my system requires more phosphate reduction after adding Chaeto back in my sump after a year of running without it. I have yet to figure that one out.....

Sorry for not responding to anyone. I've been real busy with buying a new house, job promotion, trying to get a new tank built, and also going through a hyposalinity quarintine for a new pet.

I'm getting 384 doses per day with a total dose of 105.6ml

60min/hr x 24hr = 1440min/ 3.75 = 384 doses x .275ml per dose = 105.6ml dosed per day.

[insomniac2k2]

Just wanted to note that I've observed that my tanks phosphate readings seem to be pretty consistent between .07 - .09 with a .03 +/- error range (hanna high range meter. yea i know i need the low range one...)

It seems that when I get my numbers near this range, I start to hit diminishing returns on how quickly phosphates are removed from my water. Don't get me wrong. I could easily increase my dosage and get my numbers down to .01 in a day. In my opinion, that would not be wise.

What I believe im seeing is phosphate leech from my rocks and sand, from years of buildup. It seems that as long as I keep my levels low enough, I should experience this leeching for quite some time.

Phosphate leech is a common thing. This is certainly not reinventing the wheel. I just haven't been able to see this for myself with past treatments.

 

[bmanzie]

Thank you all for the clarification.

Can someone post exactly how to put the code in the Apex? I tried using outlet 7 and here's what I did:
Outlet name 135 SeaKlear_7
Control Type: Advanced
Icon:Left/Right Arrows

Fallback:OFF
Set:OFF

If OSC 000:00/000:15/003:30 Then ON

Updated it. I got this ERROR message: Valid keywords following If are TEMP, pH, ORP,DO, Cond, Feed Cycle, SwitchX, PowerFail, Sun or Moon//ERROR: line3- If OSC 000:00/000:15/003:30 Then ON

I had a friend set up my Apex a long time ago so I have never changed it/ put in a new outlet or code. Thanks in advance!

You need to remove "If" at the beginning.

Thank you!!! :=0)

Ok guys, I'm ready to start the reactors and doser! I'm scared to death!!!! I tested my PO and they are at .0669 (Hanna low range phosphorus tester). The PO was .10 but I've been hitting it pretty hard with GFO.

So, I have the code above but want to start at a much, much slower dose! So do I shorten the 15 or increase the 3:30? I know NOTHING about how to determine how much to dose I'm guessing my total water volume to be about 120g. Help...I'm even trembling! I don't want to lose my Purple Tang!!!

Oh, Insomniac-did you get a purple tang?;0)

 

[terri_ann]

I should have said a much lower dose...not slower! Told ya I was/am scared!
