ALKALINITY | PH | BORON

Hydroshock alkalinity is a highly effective alkalinity supplement specially developed for reef aquariums, delivering a total alkalinity of 8,400 dKH. Formulated to precisely replenish carbonate alkalinity consumed by coral growth, it supports stable and robust coral skeleton formation by maintaining optimal aragonite saturation states. The inclusion of boron enhances buffering capacity, significantly reducing day to night pH fluctuations that can stress corals and inhibit growth. Regular use helps achieve consistently ideal alkalinity levels, promoting vibrant coral coloration and overall aquarium health.

Alkalinity

I'm loving how hydroshock comes with trace elements. All of my corals have been growing faster since I made the switch.

5/5 Carly Ballou Verified buyer
Hydroshock

I’m dosing all 3 bottles of Hydroshock, my corals have been much happier. I like it better than a 2 part.
