Korallin Calcium Reactor

No you already got there, If the tank KH is stable at 7.6 you already balanced the addition to the consumption. To rise the level use an alkalinity supplement (Baking Soda) once it is at the new level, if your reactor is really balanced it will stay there without the need for further supplementation. Do the same with Calcium, if you achieved a balance with the alkalinity chances are Calcium is to be balanced already so to adjust the final level use a Calcium supplement like Turbo Calcium. Once there it shall stay there. Do not use your reactor to increase or lower the levels or you will never stop adjusting.

Enjoy!
 
hmmm, good point. I will try that.

Heck, a water change with oceanic ought to fix any low calcium or alk issues.

I really doubt it... Remember that now you are now adding Calcium and Alkalinity in a balanced way. If you change water with an unbalanced salt with high Calcium and Low alkalinity, the Calcium will increase and keep on increasing with subsequent changes and the alkalinity will lower and get lower with subsequent changes.
 
I usually add baking soda to raise the alk level. Is that okay to do or should I start using a different salt? Is there such thing as a salt with a match calcium/alk? I know IO is low on cal and high on alk...

All salts have pros and cons but none other but Oceanic has such unbalanced levels. With all salts you may need on ocassion to add a suplement for either Calcium or Alkalinity but you will reduce the mismatch with salts more specific for reefs like Kent, Reef Cristals or Tropic Marin Pro. I switched from Kent to Oceanic for about 3 buckets (about 10 water changes) and during all these time my levels were all over the place until I went back to Kent. To give you an idea on teh latest batch after 24 hour mixing on RO DI I got Ca at 400ppm, Mg at 1275, Alkalinity at 9 which I would consider a prety good balance.
I would also advice to try to match the levels on the water to be added to those you are seeking to maintain this will take you a long way toward stability.
 
I am a bit confused?? I have read many posts to this thread and I cannot figure out what to test for? Is dkh the same as kh, which is the same as Alkalinity???
 
There are basically three units of measure for Carbonate alkalinity, Those are PPM (Parts per Million), meq/lt, and dkH.

The conversions are as follows.
1 meq/Lt = 50 PPM
1 dKH = 17.86 PPM
1 meq/lt = 2.8 dkH

All are units of measure of Alkalinity.
 
I have not tried any of the Tropic Marin Salts yet but here is the analysis of one batch of the Tropic Marin Pro

SG 1.025
pH 8.17

below via Salifert kits:
Ca 430 ppm
Alk 8.0dKH 2.86 meq/L
Mg 1200 ppm

One batch may not be enough to establish a pattern but it seems prety well balanced too.
 
seems about the same as kent. I can get the regular tropic marin for $50 shipped for a 200 gallon bucket. That's about the same I pay for oceanic...
 
Look at the list for all type of connector types and diameter.
For 1/4 inch there are in PVC:

22299 is female threaded
22317 is male threaded
22318 is Barb (for hose)
22326 is John Guest for 1/4 tubing similar to the one used in RO/DI units. This is the easiest to install is you are using that kind of tubing.
 
Hey guys, just to let you know that this is some awsome
advise and knowledge being shared and thats what makes
this forum so unique. Thanks before I get started.

OK, now I have a Korallin C-1502 I have read this post from page 1
and also have set it up according to KC instructions . My DPM
are 42 and my BPM are 11, I took the tank & effluent reading
after an hour or so of letting the reactor run and the readings were

Tank: PH 7.87 Alk 12.3 Dkh
Effluent: PH 6.63 Alk 32.64 Dkh.

So I had good readings from my effluent and decided to just let it
run and start my daily testing of the tank. well after a couple of hours
i noticed the PH of the effluent was dropping, before I had went
to bed last night it was down to 6.43 and this morning it is at 6.22
is this normal will it raise back up or is there something that is
wrong. they only changes that I made to the reactor was I
increased the DPM to 50 DPM to try and get the PH up.

Mine has slowly dropped from 6.8 to 6.6 over the last few days....

Why would that be?

Wait a full 24 to see if it comes back up again, sometimes changes in room temperature affect the valve settings. If it does not correct itself check that your effluent rate has not come down as it usually does over time as the media settles.
 
I have let it drip for 6 hours at the rate of 58 DPM and
8 BPM and the PH of the effluent is only reading at 6.17
what should I do raise the DPM or lower the BPM some more
I am lost at this point. I need help!
