calcium reactor

Have been experiencing low alkalinity with my sps dominant mixed reef tank. Any suggestions as to what I should do? I was wondering if it is possible the current calcium reactor is too small. The tank is a red sea 525XL (525 Liters) plus about 50 gallons of sump. Current alkalinity is 6.1...

im just setting up my 2 stage calcium reactor and i have MANY questions.. i want to try and follow this method. i was going to use a steady stream method where you do not count the drip rate but use the melting point to adjust. current equipement list: geo reef 510 reactor (main) geo reef...

I currently have slightly low alkalinity between 6.4 and 7 and high calcium (a little over 500). Things in the reef are thriving. I have heard you can set the reactor for the desired alkalinity and the calcium will fall into proper range since it’s all about balance. pH is fine (maybe a...

Hello, I’m looking to get a feed pump for my CA reactor and came across this: Stenner E20T4H71S8 Timed Compact Peristaltic Pump, 80 psi, 21.7 GPD; 120 V/60 Hz https://www.coleparmer.com/i/stenner-e20t4h71s8-timed-compact-peristaltic-pump-80-psi-21-7-gpd-120-v-60-hz/7420906 It’s continuous...

Used. No probe. I used on my calcium reactor (also available). Worked flawless until I took system down. $90 shipped.

To save space in my tank stand, I am considering placing the reactor about 75 feet away from the 120 gallon display tank. It would be in the lower level of my house where I have my water mixing room. Since I plan a mixed reef that will not have a heavy SPS load, the reactor's effluent volume...

Willing to trade my unused Maxspect Gyre XF-250 w/ controller and Icecap Interface Module for an external calcium reactor. I don't need a regulator. I went a little crazy buying for my tank build and realize I don't need the XF-250 gyre. (I'm going to use the XF-230, which I already have)...

Want to send out a thank you to Travis "FishofHex" on YouTube for ordering this custom GEO 72"x20"x15" PRO sump with remote 30 gallon ATO reservoir and GEO CR818 and SMC415. Make sure to check out his YouTube channel for more info on reef keeping and his 300 gallon build.

Hoping there might be some interest. I purchased this Calcium Reactor about 10 months ago and never got around to setting it up. It is just sitting here taking up space so I thought it might have be of some use to someone else. Original packaging... I will add some pictures or you may request...

Roughly 24" tall and 6" wide Jecod DCT3000 circulation pump Should be good for up to 400g by my estimates. So what do you guys think? Any recommendations or improvements you could suggest, I'm interested in hearing your thoughts!

I have a new 5 gallon bucket of color changing SodaLime for use in CO2 scrubbers, usually associated with a Calcium Reactor to combat low pH issues. I was buying it from BRS in smaller batches and found it at a local medical supply. Since then I have sold my Calcium Reactor and as a result I...

Here is my problem. I need to supplement my magnesium daily to keep the level above 1200, even though the concentration of kH and Ca remain relatively stable. Each day I am adding 25 ml of liquid magnesium supplement. The many experienced reefers in my local club are stumped. 30 gallon JBJ...

I am in the market for a new calcium reactor for my 120 Mixed reef Tank! I am slowing adding SPS frags on a weekly basis. I am running an Eshoops Doser w/ salve and adding ALK WHEN NEED TO BE, CAL MAG AND KALK in my Avast Kalk Reactor that is connected to my Apex with two float switches. I am...

We want to send out a thank you to Justin a local reefer in Ohio for ordering this custom GEO CR818 calcium reactor. Evidently he is an OHIO STATE BUCKEYE fan. O-H Thank you, GEO

If you have one available in excellent condition, - hit me up, I have cash! Also, looking for a CarbonDoser Electronic CO2 Reg as well.

I have a nuvo fusion 30L aquarium that I want to do a mixed reef with. I dont really want to mess with kalk unless I have to. However, I am having a hard time finding people with AIO tanks that use dosing pumps. And I have only seen one person use a calcium reactor for a AIO. Any advice on how...

Bought a used Minical a while ago and then started to rebuild the tank it would eventually get hooked up to. So, reviving this reactor has been on the back burner. Now I'm ready to get it rolling again. I'm just trying to find some people who use a Minical (or Procal), and know how to get it...

I wanted to run a CO2 reactor on my 20 gallon sps reef, but have decided to stick with two-part instead. I'm selling the reactor, ph probe, and CO2 cylinder from that setup. These are very lightly used--only one month. If you can pick up the CO2 cylinder it is currently full. Otherwise it...

Hi I am having problems with GEO cr618 calcium reactor with AP regulator which has been PIA since the day one. First of all reactor and AP regulater both came with faulty check valves but that I solved with a check valve I had from my last reactor. AP regulater are best known in the market but I...
