LaCl Reactor

Had my first LC clog today (on my new reactor feed design). Seeing that I never had a clog before, ill have to figure out what i did differently before and make some adjustments.

Looks like the clog started further down in the T and then worked it way up to the check valve. Soaking in vinegar now and will throw it all back online soon.
 
Would a venturi like on older skimmers suck in the LC (and air) and have enough velocity (and suck it into a big enough pipe) to not clog? A skimmer style reactor chamber to keep things in solution and a filterfloss reactor on the way out?
 
That would surely work. And you would have the benefit of using turbulence to mix it very well from the get go.

That said, I've had one clog in a year. If I start clogging more often, then I will definitely think about new design. Otherwise I will just write it off to quarterly routine maintenance.

For my new "design" (really, its just a minor adjustment of my first one to make it work in the area that I have placed it), I think that the clog may have been either cumulative. I never cleaned it up after I moved and changed tanks.

I'll see how long it takes for the next clog and make changes accordingly.

I've been reviewing this thread for the longest time and have not pulled the trigger. I guess my question is, can you show a pic of how you modified the BRS 2 stage reactor for your phase 1 process? I know that you mentioned you reversed the flow to get the LaCl to mix in the center chamber before heading out to Phase2, but my head still can't seem to wrap itself around the idea of how you did it.
 
When you look inside the chamber, you will see that when the flow comes in, it just dispurses the water to the main chamber, and then funnels into a hole that is dead center in the middle of the top. So I basically just made the incoming water go "In the out door" (thank you led zeppelin).

To extend the mixing down toward the bottom of the chamber, I just used a piece of tubing that slipped over the lip and cut it to length.

On my second version, I just kept the flow going the same direction and just ran one of the BRS GFO containers http://www.bulkreefsupply.com/catalog/product/view/id/1656/

Which essentially accomplished the same goal.

i just ordered the derKroon LTH100 Lanthanum Reactor online, lets see how this holds up. i have not seen any review or nor seen anyone here on RC using this commercially made reactor.
 
I have a DIY dual penductor injected skimmer that sucks in gallons of air and a mixing chamber that's 8ft long. Water enters at the top and exits at the bottom with the dual injectors about 2 feet up from the bottom.

I absolutely have no filter media. I believe that any media hurts the plankton population (as does over skimming). I turn the skimmer off at night.

I'd like to try this by dosing at the top of the skimmer believing that very little can make it out... I can dose as slow and as long as needed during the day.

Any concerns? Ideas? Warnings?

If any precipitate makes it out, it can impact the fish. Certain fish, especially tangs are more sensitive to the precipitate as it effects their gills and is known to kill them if enough gets into the water. If you notice any cloudiness of the water, that is a tell tale sign that the dosing is too high or that precipitate is entering the system. Also, anemones and other inverts may be negatively impacted as well. If you are going to test your solution, I would strongly suggest using a 10 micron sock at the discharge to filter out any precipitate.
 
If I drip directly into the skimmer, then the output will likely be plankton free - I can put a sock on the skimmer output.
 
I ran my doser directly into the feed to my skimmer. No filter on the output.

I used 60ml a day (1ml per gal per day on my 600gal tank). Went with ATM brand to start.

My three zebrasoma started breathing fast (yellow, purple, sailfin) but corals loved it.

Cut back to 30ml, no fast breathing.

Cut back to 20ml for safety.

I'll provide feedback as I see it.

My skimmer's output runs into my macro algae refugium and then to the DT.

I'm also heavy on Kalk dosing (for reference).

I think the tang sensitivity is to the LaCl salt, not the particles that precipitate out.

20ml a day for safety? If your fish are breathing hard, you are without a doubt overdosing and your skimmer isn't nearly as effective at removing the precipitate as you think. I'm not sure how much you are diluting or how weak that Agent Green is or maybe I'm just misunderstanding you.. I can cut PO4 from .10 to .05 in a single dosing with 5ml of Sea Klear LaCl mixed with 1 Liter of RODI water. I drip that 1 drop a second via an IV bag into a 10 micron felt sock over the course of several hours. I have never had an issue with my fish breathing heavy and I have several tangs along with about 40 other fish and two giant RBTA's. I never have any cloudiness in my water either. In my 600+ gallon system this treatment reduces Po4 from .10 to .05. I test my Po4 with a ULR Phosphorus Tester.

My point is that if you are using 20ml of LaCl a day, something is wrong and or you are playing with fire.
 
Not that you may not end up ok, i feel that your playing with a real risky dose rate.

Did I read this correctly. That you are dosing 60ml LC a day? Or are you dosing 60ml diluted solution a day?

My most recent dose rate has been increased a bit due to moving and switching tanks. I also allowed phosphates to go completely out of control.

My latest mix was 60ml per gallon RODI @ a dose rate of 25 seconds per 7 minutes. My tank is 230 gallons.

I also wanted to note that I also feed directly into my skimmer, but I still use a 2 stage mixing and filter floss/carbon reactor setup in front of it. I feel that that is plenty of security to make sure that most precip and unreacted LC never see my tank.

Fallback OFF
Set OFF
OSC 000:00/000:25/007:00 Then ON
If Sw2 CLOSED Then OFF
If Sw6 CLOSED Then OFF
If Outlet RTN = OFF Then OFF

The ATM dosage guideline is 1ml per gal per day for every 1ppm reduction.

I use a 1440ml RODI solution with 120ml of ATM. Dosing the solution at 10ml an hour (240ml a day) so that's the equivalent of 20ml a day.

At 60ml, my tangs were breathing heavy. At 30ml, they're not. I went to 20ml to be on the safe side.

Thanks for the immediate assumption that I'm doing something wrong, but all my 20 fish are healthy and eating well.

I have an macro algae refugium that is overgrown weekly, so my phosphates are not just high, they're very high. The test kit doesn't mean anything, but my algae growth does.
 
Ditto. I hope that I am misunderstanding your treatment rate as well. Seems dangerously high. :/

To be clear, I've been doing 100gal water changes a week for a couple of months now. Here's what my DT tank looked like:

The reasons behind my phosphate levels are another story.
