Korallin

Korallin C-1502—Rated for up to 400gal. Reactor height: approx. 15.75"; Diameter: 4.50"; Ground: 6.30"; Filling amount: 3 kgs (6.6lbs); Eheim 1048 Pump.

The internal recirculation flow rate of the C-1502 is around 80 g/h. Since that this is a pressurized Kalkreaktor, the dissolution of the media by the carbonized water is enhanced. The effluent rate is only about 0.25 g/h at 40 drops/min. Thus explaining the efficient CO2 & media use. CO2 is being introduced into the Eheim powerhead direct—this is the most efficient Aspirating-Venturi method.

Features:

  • Top-loading & access w/ enhanced O-ring seal
  • `Auto-fill` Integrated Bubble Counter on one water circuit (ie: water never evaporates)
  • Detachable Tru-Union couplings w/ O-rings for easy handling, safe shipping, upgrading and leak proof
  • Integrated `industrial-grade` Brass Check Valve from German Air Pressure Systems to prevent back flow of pressurized saltwater
  • Improved engineering for stronger water circulation and suction
  • Secure German airline tubing connectors
  • Medical-use Miniature Quick Disconnect Couplings w/ shut-off 3 Inlet & outlet facing same direction
  • Special elbow for flexible airline tubing mounting
  • Heavy-duty Excelon construction w/ no unsightly and fragile hangover tubing
  • Top pump-mounting design
  • Self-suction water intake by the silent Eheim pump eliminates the use of a dedicated powerhead, gravity-fed or tee-off methods. It also serves for water recirculation.
  • Water circuit interruption in case of CO2 overdose—our exclusive CO2 Safety Feature
  • Visual excessive CO2 check w/ ventilation valve for quick release
  • Dual effluent outlets to suit different systems
  • Aspirating-Venturi technology utilizes only 10 CO2 bubbles/min. and up—most efficient use of both CO2 gas and CaCO3 media
  • The most compact and versatile positioning Kalkreaktor in its class—6.25" small foot print + 15.75" total height—external or in-sump
  • Micro-adjustable miniature ball valve to maintain a consistent effluent drip rate
  • Slightly larger (German size) airline tubing for more consistent water flow
  • Strainer to protect Eheim pump from loose media particles

“Nice, But...”
4.0

As stated by others, you will get an air gap at the top when running a slow drip causing the pump to airlock. Save yourself the aggravation and run the normal drop line AND run the top bleeder line as well. Dial them both in so any air that gets trapped in the top can bleed out on a daily basis.

“Korallin OK, but...”
3.5

No negative comments about the C-1502 since it seems well built. However, if you're planning on buying the kit (reactor and CO2 setup), there's a few things you should be aware of and to plan out:1. The C-1502 Korallin reactor does not come with a reactor lid for the pH probe to control the CO2. In ...Read More

“One year review”
3.0

Ok. It's been 1 full year since installation. First, the reactor needs to be lower than water source. No extra micro pump is really required as long as your outtake is below or same level as the reactor. You will get air trapped up top of the reactor and the best solution I have found is to use t...Read More

“A good choice, easy setup”
5.0

Got a used one and its very simple to use. Only thing I don't like is it doe not have a PH probe holder. Although you can set the CO2 rate in the bubble count in the chamber, I much rather to control it with a PH controller. Quick fix, ordered a Geo probe adapter, drilled the top of the reactor, tap...Read More

“Good”
3.0

It seems it is working fine, but some how the bubbles stop after some minutes of being working. It need the micro pump to get a better idea of what is wrong. Thanks.

“not worth it”
2.0

I got this product 2 months ago and am still having trouble dialing in the bubble counter. It is very inconsistent due to the low quality of the fine needle adjustment. I have taken the tubing apart twice in order to fix a slow leak at the pump fitting. The media that comes with this package is junk...Read More
