FAQ

Are high nitrate levels harmful to fish?

High nitrate is harmful to fish but is significantly less toxic than ammonia or nitrite. Effects of high nitrate levels are more gradual if parameters go untreated – fish will eventually lose their appetite and grow sluggish and inactive over time. High nitrate also contributes to rapid algae blooms in aquariums.

How often should I use API NITRATE TEST KIT?

Use API NITRATE TEST KIT weekly or bi-weekly to ensure your nitrate levels are safe for fish, or whenever you suspect you may have high nitrate levels in your tank.

Clean Ingredients Without Compromising Performance
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
My wife purchased Davids Fluoride Free Toothpaste because she wanted a cleaner alternative without all the unnecessary additives found in many mainstream brands—and it’s exceeded expectations. First, the ingredient list is refreshingly simple. No fluoride, no SLS, and none of the artificial extras you often see in traditional toothpaste. It feels good knowing we’re using something more thoughtfully formulated. What really stands out is that it actually works. It leaves your mouth feeling genuinely clean and fresh, not just artificially minty. The texture is smooth, it foams lightly (without being overwhelming), and it rinses clean without any residue. Over time, her teeth look brighter, and it does a great job keeping plaque under control. The mint flavor is crisp and natural—not overly sweet or harsh. It strikes a nice balance between refreshing and subtle. It's safe, sturdy and does not bother my wife's sensitive teeth. The size is perfect to keep at home. If you’re looking for a fluoride-free, SLS-free toothpaste that still delivers whitening and antiplaque benefits, Davids is an excellent option. It’s a clean upgrade that doesn’t sacrifice performance.

Pros and cons listed below, you decide
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
II like the flavor (peppermint) and that is is a healthier option for tooth paste - BUT - the cap and tube needs redesigning. The cap is hard to screw on most of the time flying onto the counter or the floor and also easy to confuse which end to screw on if you're not paying attention as one end is to puncture the end of the tube to get the paste out and the other to cover the tube after use. The tube is too hard to get all the product out and to roll because I believe it is made of metal instead of plastic which is good but not so good. This is already very expensive and you cannot get all the toothpaste out. The cons are why I gave the 3 stars otherwise this is a 5 star for me and my husband.
