Seachem Reef Complete 250ml

Seachem Reef Complete is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide calcium (Reef Complete) and carbonates (Reef Builder™ or Reef Carbonate™).

Reef Complete also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium.

Reef Complete is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete is blended to a higher pH in order to force the ammonia to gas off into the atmosphere. In addition, Reef Complete is more concentrated than any other liquid product on the market. Reef Complete contains 160,000 ppm calcium. Our nearest competitor’s product is only 110,000 ppm calcium.

  • Liquid ionic calcium source
  • Most concentrated calcium supplement on the market (160,000 mg/L)
  • 100% soluble. Be wary of products that are milky white or need to be shaken

Beginner
Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Check calcium every 2 weeks and adjust amount or frequency accordingly.

Advanced
Check calcium level (use Reef Status™: Calcium to measure calcium), then follow addition regimen above until calcium is adjusted to 380–420 mg/L. Each 5 mL/80 L (20 US gallons) will raise calcium by about 10 mg/L. Quantity or frequency can be adjusted, but do not exceed 12.5 mL/80 L (20 US gallons) per day. Thereafter, use as required to maintain calcium.

Expert
After determining the calcium consumption rate, set up a continuous drip system. Use the following formula (or skip the math and use our Dosage Calculator) to determine how much to add to your top–off water: m=vc/160 (m=mL of product to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L].

Notes
If used with Reef Calcium™, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status™: Calcium to measure calcium.

DO NOT OVERDOSE: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart.

My children and grandchildren come over for dinner every Sunday night. These paper plates are ideal and sturdy enough for everyone. I can use it for everything I prepare. When I start to run low on them, I always order more. This is a staple in my house!

Strong, convenient, and perfect for busy setups
Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls), Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls)
These bowls are a staple in both my home and now adding them to Airbnb property. They’re sturdy enough to handle soups, cereals and even heavier meals without getting soggy or collapsing too fast. I love that they’re microwave safe and compostable makes cleanup easy and eco-friendlier. The 20 oz size is generous and the pack of 6 lasts a good while for sure especially when you’re hosting guests or just want a no-fuss option for meals (or for the teenage boys and their friends coming for a quick bite). You'll appreciate the convenience, and I appreciate not having to worry about dishes piling up all the time. Design and color has some fun to it over the typical white basic kind. Definitely a good value and also doesn't have that weird scent or doesn't leave that weird taste to it. If you’re looking for durable, disposable bowls that don’t feel flimsy, these are a solid pick.
