Jeremy you are more than welcome to come see mine as well (closer to you than Nikki ). We are both running controllers though so it will be slightly different than what you are going ot setup with your timers (although that's what I used for years). Nikki's will be much prettier and neat to look at.    Krazie

I did.  I have the dosers, now I just need to make it to a Home Depot to pick up some timers.  I currently only have a day/night power strip.  And thank you for the offer for help and to check out your dosing setup.  I may end up PM'ing you.

Good doser IMO. And Nikki Just a fun poke at Engineers all I have met have taught me tons. Also fun to work with from design to finished product . Smile]]> Mon, 06 Jan 2014 20:46:15 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68735&PID=549439&title=twopart-dosing-rookie-question#549439 <![CDATA[Two-Part Dosing - Rookie Question : Did you get the BRS dosers?

Awesome.  Lightbulb just went off.  I was over engineering it.  Dilution is a great solution.  I am more comfortable using a digital timer until I can afford a controller now.  I just read nightmares on digital timers.  But this will make me more comfortable.  Thank you.

Ah, but see...I was a mechanic in my previous life (airframe & powerplant).... There are plenty of bad engineers out there, but there are plenty of good ones too. Don't stereotype! :D]]> Sun, 05 Jan 2014 07:12:47 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=68735&PID=549225&title=twopart-dosing-rookie-question#549225 <![CDATA[Two-Part Dosing - Rookie Question : So just to make it simple because...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=68735&PID=549220&title=twopart-dosing-rookie-question#549220 Author: Akira

So just to make it simple because all engineers over engineer . Set your timer see what it doses . Check a chart and just get close. You will see a trend as you get more stable , might require more or less,  When I set mine up I dosed half of what I needed . Then added more time until it was stable. Didn't matter if I wanted 450 ca or 420 ca just a # that was the same everyday. Then a simple bump up and it stayed stable. 


As I always tell my boss ,,,(He's a engineer and I'm a maint Mechanic so I'm the real problem solver) 

"Just because you can draw an #+$ on paper doesn't mean we can make it crap! "

Ok, I got tired of trying to type on my phone...I'm at my computer.

I wrote up this little blurb on my website on how to mix up the two-part solution based on Dr. Randy Holmes-Farley's recipe. So, mix that up first of all. This will create a solution with a known chemical level which can then be used to dose the correct amount.

http://www.reefdup.com/2012/12/16/how-to-make-2-part-dosing-solutions/

Then, test your water. Use the website below to calculate your dosing requirement:

http://reef.diesyst.com/flashcalc/flashcalc.html

So, as an example, if you measured 7.8 dKH alkalinity, have a system water volume of 100 gallons, want your alkalinity at 10.0 dKH, and used Randy's Recipe 1 Alkalinity Part, then you need to dose 157.1 ml of the alkalinity supplement you just made.

Retest about an hour later (keep in mind that you shouldn't dose high amounts at once). Dose more if required to get your chemicals to your desired levels. Your solutions may not have been mixed fully, you might've used a less potent chemical, etc....so slight variations may occur (but nothing significant).

Once you have your parameters where you want them...stop. Wait several days (I prefer 4 days) without testing or dosing (keep replacing evaporated water though!)

Retest. As an example, say you started at 10 dKH on Day 1, and on Day 4 you were back down to 7.8 dKH. Replug your numbers into the reef calculator. You should get 157.1 ml required. Dose that amount. You should have your alkalinity back up to 10 dKH. Then, divide the dosing amount required by the number of days without dosing (so, 157.1 ml divided by 4 days is just over 39 ml/day).

If your pump doses 1.1 ml per minute, you'll need to dose for about 35 minutes each day given those example numbers.

Retest weekly until you're confident in your pumps, calculations, etc. After that, retest and adjust monthly. As your corals grow, so will the need for additional supplements.

Here's the science behind all this:
