  • Supplies a properly balanced buffer system that yields an industry leading pK of 8.6 which makes pH maintenance of 8.3-8.5 easy
  • Will safely raise marine pH while adjusting alkalinity

Many competing buffers for reef aquaria are simply sodium bicarbonate. Such buffers have a pK of only 8.0 in saltwater and simply are unable to maintain a pH above 8.0. The low buffering pK is a function of the low carbonate/bicarbonate ratio.

eight.four™ supplies a properly balanced (carbonate/bicarbonate) buffer system that yields an industry leading pK of 8.6 which makes pH maintenance of 8.3-8.5 easy. A higher pK increases the buffer's ability to counteract inevitable acidic sources in the water. eight.four™ will safely raise marine pH while adjusting alkalinity. eight.four™ contains a concentrated, balanced blend of bicarbonate and carbonate salts designed to restore disrupted buffer systems and increase carbonate alkalinity.

If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained, the system may be ionically unbalanced. Check magnesium levels. If magnesium is low, use ions™. However, if magnesium levels are within optimal range, the buffer ratio has likely been disrupted (the buffer ratio changes as a natural consequence of the buffer's ability to counteract acidifying sources such as organic acids). You can raise pH without raising alkalinity using balance™.

Unlike competing products that require multi-day interval dosing when combined with carbonate supplements, eight.four™ can be dosed daily and within minutes of our calcification™ as well as balance™ and ions™

So, we have had a DOA policy that has always been very generous. But lets just KISS, I mean “Keep it Simple Stupid”.

- If you have an item that unfortunatly arrives at your door in it’s bag dead, its covered.

- If you put a coral in your tank and within 2 hours of delivery it is dead, it’s covered.

- If your shipment is delayed by UPS and your corals arrive dead, they’re covered! (photos must be send within 2hrs of delivery even if shipment has been delayed)

DOA coverage means you will receive store credit for the item you purchased to use either for a like replacement item or on a totally different item! We do NOT cover the cost of shipping if you have a DOA item. DOA credit may be used only once. DOA credit may not be used to pay shipping fees nor counted towards the amount spent required to reach free shipping.

All DOA corals must be photographed within 2hrs of delivery, whether they’re in the bag or tank.

We do work with each customer on a one on one basis as each situation is unique! We care about you and our corals, and most importantly we want a good experience for everyone!
