Aquavitro Ions

Aquavitro Reef Ions is used to restore magnesium levels in reef aquariums without adding ammonia, supporting the calcification of reef organisms.

  • Restores magnesium by employing the most concentrated (90,000 mg/L), fully dissolved magnesium
  • First and only liquid magnesium supplement that does not contain ammonia

Like calcium and strontium, magnesium is used in the calcification of skeletons of reef organisms. In many cases, magnesium is used in place of calcium for calcification. In addition to its role in calcification, magnesium is used by organisms ranging from bacteria, to coralline algae to fish.

How can you be sure if magnesium levels are deficient? There are a couple of indications; severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels (more on ionic imbalance).The best way to tell if you need a magnesium supplement, though, is to test for it using a magnesium test kit such as Seachem's Reef Status®: Magnesium & Carbonate and Borate Alkalinity.

If you've determined your magnesium levels are low, supplementation with ions™ is necessary. ions™ restores magnesium by employing the most concentrated (90,000 mg/L), fully dissolved magnesium and does so without adding any ammonia. Other liquid magnesium supplements inherently contain ammonia because the magnesium chloride used in their production contains ammonia. This is a result of the mechanisms for deriving and/or producing magnesium chloride. aquavitro has gone to considerable lengths to remove this contaminant and a proprietary process makes ions™ the first and only liquid magnesium supplement that does not contain ammonia.

Using a fully dissolved magnesium is critical. Some magnesium supplements use a magnesium source that is simply not soluble, that is, unavailable. This means it can never be utilized by reef organisms, and is, consequently, of no value. If the product itself is milky white or the instructions direct the user to shake well, more than likely, a substantial amount of magnesium is not being utilized (the same is true of calcium products). ions™ also includes strontium and boron in the NSW ratio of 1.7:1 to avoid ionic imbalance with long term use.

Directions:

Beginner: Use 5 mL for every 90 L (25 US gallons) twice a week. Check magnesium once a week and adjust amount or frequency accordingly. Note: each inner cap thread is approximately 1 mL.

Advanced: Check magnesium level, then follow addition regimen above until magnesium is adjusted to 1200-1350 mg/L. Each 5 mL/90 L (25 US gallons) will raise magnesium by about 5 mg/L. Quantity or frequency can be adjusted, but do not exceed 25 mL/90 L (25 US gallons) per day. Thereafter, use as required to maintain magnesium.

Unlike competing products that require multi-day interval dosing. ions™ can be dosed daily and within minutes of the entire aquavitro line.

FAQ:

My tank only has a magnesium level of 1050 mg/L. I have been using ions™ daily for the past week and my magnesium level is not increasing very much. Do you know why this is?

A: Each standard dose of ions™ will raise magnesium by 5mg/L. In cases where magnesium is severely low, it is acceptable to add up to 5X the recommended dose each day in order to see a more notable increase in magnesium. Unfortunately, it will take a large quantity of any magnesium supplement in order to increase magnesium by such a large amount (about 300mg/L in your case). For the future, you may want to look into using a salt that contains a more appropriate level of magnesium, such as our salinity.

What if I want to raise strontium without raising magnesium

A: Strontium use by corals is not completely understood; much of its use seems linked to temperature or the absence of calcium in systems. It is a factor in the stability in the skeletal systems of corals. Typically, its rate of utilization will not exceed the rate of magnesium utilization. So ions™ offers a continuous supply necessary for all systems. So will it build up? No, it shouldn’t, but if it does, there is a margin of safety of 10X natural seawater for strontium. Any normal water change would negate this concern. If one wanted to run elevated levels of strontium, by all means use Reef Strontium™.

Do you still have a second seal on the ions bottles, 150 mL, 350 mL?

A: No, we have actually used a special cap style on the aquavitro line that prevents the need for an additional seal. The cap will seal tightly once closed.

Would recommend!
Color: White, Size: Queen
I bought this mattress topper for my teenage daughter for her bed. It was on sale when I purchased it and when it arrived I loved the quality and softness of the topper. Great buy for the price! It stays in place and fits as sized. I have yet to launder it, but I would assume it will wash up just fine. My daughter loves it and makes her bed dreamy.

Saved me so much money
Im loving this mattress topper. It has added a noticeable layer of comfort to my firm mattress without making it feel too soft. The cushion is plush yet supportive and has made sleeping more comfortable overall. The bamboo feels soft and breathable. It fits on the mattress with the deep pockets and stays in place alk night. Setup was easy and it fluffed up after unpacking. If you have a firm mattress and want extra comfort without replacing it, this topper is a great option. Highly recommend

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.

Great upgrade for a rental apartment mattress
The mattress in my rental place is firm to the point where it almost feels unfinished. Instead of replacing it, I decided to try adding this topper. It made an immediate difference in the way the bed feels when I sit or lie down. There’s a nice cushioned layer that softens that “flat” feeling but still holds its shape. Another thing I noticed is how breathable it is. I expected thick padding to feel warm, but the airflow here feels better than the original mattress surface. Even after moving around, it never felt heavy or stuffy.

Soft and Comfortable Topper
I got this bamboo mattress topper for a small single bed we keep in our guest room, but I ended up testing it out myself first. The material feels soft and breathable, which is nice because that room can get a little warm in the afternoons. It adds a good amount of cushioning without making the bed too soft. After a couple of nights, my back actually felt better compared to the old mattress alone. I also appreciate that it’s machine washable, because our guest room sometimes doubles as a nap spot for my son after swim class, and spills happen. It dried pretty quickly in the dryer and kept its shape. Overall, it made the bed feel much more comfortable and fresh.
