Following a fertiliser explosion at Highlands Farm on 24 July 2026, Coral Passion has stopped trading from the site. Our insurance claim with MSIG Europe is still ongoing, but despite our efforts it does not look promising, and the future of the business is uncertain. Thank you to everyone who has supported us. I am still available & working on aquarium installations and maintenance. For more information, please contact tony@coralpassion.co.uk.

Part 1 Only

A complete 2 Part dosing system which significantly enhances your aquarium pH, inorganic and ionically balanced, Z-pHplus contains all main Macro, Micro and Trace elements your corals need to thrive:

  • Z-pHplus allows you to provide your reef aquarium with optimal amounts of Alkalinity and Calcium whilst significantly increasing your tank's pH.
  • Z-pHplus dosed as recommended will maintain your aquarium's ionic balance.
  • Z-pHplus supplies your reef with boron, bromide, calcium, chloride, chromium, fluoride, iodine, lithium, magnesium, potassium, sodium, sulphate, strontium, and many other important trace elements in a level optimised for a high pH environment.
  • Z-pHplus can increase coral growth by 2x other dosing methods, nonetheless increased dosing consumption is to be expected.
  • Tests have proven that Z-pHplus is more effective than Kalkwasser or CO2 scrubbers at raising pH.
  • If your tank has a pH of 8.15 or below  Z-pHplus is the best dosing solution for your tank.
