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.

The best sunscreen on the market
Size: 5 Ounce (Pack of 1), Style: SPF 50+
The best sunscreen I've ever used. I burn super easy, just 30 min outside without protection and I'll be a lobster the next day. I can apply this once in the morning and be protected all day. Pros: - Doesn't wear off quickly - Haven't had a single sunburn since I started using it - Doesn't have a strong chemical smell - A little goes a long way - Resists sweat well Cons: - Has a white cast so you really have to rub it in - It doesn't sit light, you can definitely feel it on your skin I would recommend this to anyone and everyone looking for sunscreen.

Love this sunscreen!!
Size: 5 Ounce (Pack of 1), Style: SPF 50+
This is my favorite mineral sunscreen. It goes on white, but the white cast leaves very quickly. The SPF 50 keeps me adequately covered in the Arizona sun and I've never gotten a sunburn when I have it on. It's a must have if you enjoy the outdoors in the summer.

Does seem different from blue bottle version
Size: 5 Ounce (Pack of 1), Style: SPF 50+, Size: 5 Ounce (Pack of 1), Style: SPF 50+
I have to say this one is interesting. I’m use to using the Blue Lizard in the all blue bottle for the better ingredients & still effective against UV rays with the only downside of the white cast. With that being said this one does dry m o r e clear, but does seem to take longer rubbing into the skin. I also noticed I get much darker/ more red when using this one compared to barely any skin change with the all blue bottle during a beach day. It still says 50+ SPF, but I have noticed more of a pattern of that happening. Depending on how much/ long I’ll be in the sun I might use the other instead, but if I am planning to go somewhere more of a social gathering I may use this one due to it drying clear.
