Brightwell Aquatics NeoTiger KH+/GH+ is a precision-formulated mineral supplement designed to remineralize purified water for freshwater shrimp and planted aquariums. Tailored specifically for Neo Caridina and Tiger shrimp species, this blend balances both general hardness (GH) and carbonate hardness (KH) using a scientifically-backed ratio of essential elements. Ideal for aquarists using reverse osmosis (RO), deionized (DI), or very soft tap water, NeoTiger KH+/GH+ adds calcium, magnesium, potassium, sodium, and trace elements to support shrimp osmoregulation, plant nutrient uptake, and fish health. It helps stabilize water chemistry for long-term wellness while promoting vibrant coloration and strong molting cycles in shrimp. This formula also improves aquatic plant growth by activating enzymes, building chlorophyll, and strengthening cell walls. Silica provides structural support for roots and helps buffer pH changes. Whether you’re setting up a new tank or performing a water change, this product allows you to adjust your GH and KH precisely without overcorrecting, keeping your system stable and thriving.

Customers say
Customers find the mineral supplement easy to use and consider it good value for money. However, the GH aspect receives mixed feedback, with some saying it works well while others report it doesn’t raise KH levels. Additionally, the product causes water to become cloudy, and customers note that it leaks out of the bottle.

Fix for melting plants
Great value for money, saw a significant change in aquarium ph levels. Water quality improving, hopefully my plants can bounce back and have some longevity and not melt away.

Exactly what I Needed
Increasing my Kh and Gh perfectly, my water is too soft so I needed some mineral additive. This is perfect for the price and amount. The pump is easy to use and easy to measure

Shrimp skip…
Really weak formula. It took 16 pumps (that’s 32ml, tested pump volume). To raise 5gal (about 19L) bucket of tap water GH from 2 to 7. KH from 1 to 4. Even tried testing after an hour to confirm results. And made it insanely cloudy even after 2 hours. Bottle is 250 ml, that works out to under 8 (5gal) water changes. Actually ridiculous. Tested it on the water in the tank same results. Skip this one, stay with Salty Shrimp or crushed coral or something.Photo of the cycling tank it was tested on taken 2 hours after testing. (Sponge filter and Fluval flex filter active w/ purigen, sponge and bioballs). Please ignore any weirdness and dirty glass it’s cycling.

If they fix their bottles do it
Bottles leak during shopping every single time I’ve ordered so I’m not buying more but my shrimp like it since I had to use what was left for the food of shrimp kind
Great product –
Easy
My water was so heavily chlorinated and dense with mineral i couldnt use it. I had to always go buy bottled water, so i got a water softener. But cant ise satled water so i got an r/o water system which is “empty”. I can control mineral density with this. Extremely helpful. Just shake before every use

Insufficient kh
This product really does not add to ikh. You have to bring the gh too high, to get kh. I returned to Salty Shrimp for neos.
Kanut Laoharawee –
Did not add gh or kh in RO water correctly when dose per product instruction
Somehow I needed to use 14 ml of this product to raise GH in 2 gallons of water to get to GH6, but somehow kh is still not detected. Will go back to salty shrimp product.
