Red Sea KH Coralline Gro

Red Sea KH Coralline Gro is used to provide a complex of carbonate buffers, potassium, and trace elements for the cycling of new marine aquariums and ongoing support in fish-only or soft coral systems.

Red Sea KH Coralline Gro is a complex of carbonate buffers, potassium, and trace elements such as iron formulated in the ratio taken up regularly by the coralline algae.

Coralline Gro should be used instead of regular buffer supplements (such as Red Sea Reef Foundation B) during the cycling of all new marine aquariums and on an ongoing basis in fish-only or soft corals systems.

[Note: When using Coralline Gro, only use other supplements containing the elements Potassium or Iron (such as Red Sea Coral Colors B & C supplements) according to a measured uptake of each element. Coralline Gro should not be used in conjunction with Red Sea Reef Foundation ABC+]

Dosage

Ensure that the alkalinity is at optimal values and run the aquarium for 4 days at a stable salinity (compensate for evaporation daily) without adding any supplements. At the end of the 4 days test the alkalinity and calculate the 4-day dosage to replenish back to the optimal levels. Add the 4-day dosage to the system. Divide this 4-day dosage by 4 and use it as the daily dosage for the next week.

After a week of adding the daily dosage, test the alkalinity and calculate the adjusting dosage of each supplement to replenish back to the optimal levels.

  • If the adjusting dosage is significantly different from the previous daily dosage amend (increase/decrease) the daily dosage as appropriate.
  • If the measured level is above the optimal level wait for the excess to be depleted before restarting the daily supplementation with the amended daily dosage.

Continue testing alkalinity every week and make adjustments to the daily dosages as required. If you miss one or more days of supplementing add the complete amount that you have missed but do not exceed the maximum recommended daily increase.

Size: 500ml

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.
