Seachem Reef Phosphorus

Seachem Reef Phosphorus is a phosphorus supplement designed to support the growth and coloration of corals and macroalgae in reef aquariums by effectively increasing phosphorus concentrations without adding dissolved organics.

  • Phosphorus Supplement for the Reef Aquarium
  • Supports Growth and Coloration
  • Concentrated 3,500 mg/L Phosphate

Phosphorus is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. It is important to maintain phosphorus levels along with nitrogen levels in order to allow for optimal growth and coloration of corals and macroalgae.

Supplementing with Reef Phosphorus™ provides a targeted means of increasing phosphorus concentrations effectively without also adding dissolved organics.

Supplementing with Reef Phosphorus™ provides a targeted means of increasing phosphorus concentrations effectively without also adding dissolved organics. Reef Phosphorus is ideally suited for use with an aquavitro® sentia™ dose doser to maintain phosphorus at consistent concentration based on your aquarium's unique demand. Reef Phosphorus™ is easily dosed manually as well. Ideal phosphorus levels will vary but generally range from 0.02 - 0.05 mg/L phosphate. Reef Phosphorus™ contains 0.117% elemental phosphorus. Use Seachem’s Reef Nitrogen™ to achieve a balance of nitrogen and phosphorus levels for optimal results.

Directions
Beginner
Use 1/2 cap (2.5 mL) per 160 L (40 US gallons) once a week or as needed to maintain desired phosphorus levels.

Advanced
The beginner dose raises phosphate by 0.05 mg/L. To target a specific phosphate level, increase dose according to the following formula: 0.31vn=m where v= volume of tank in liters, n=desired phosphate increase, and m= volume of product to use in ml. For example, to raise 160 liters by 0.05 mg/L phosphate you would use 0.31*160*0.05 resulting in 2.5 ml to dose. For reference: 1 US gallon=3.8 L.

Cute sky blue linen suit for toddler!
Size: 3, Color: Sky Blue, Size: 3, Color: Sky Blue
I got this Trasign Kids Linen Suit in sky blue for my 2 year old, thinking my wife said “blue” (turns out she meant navy or something darker 😅). I actually really like the light, airy sky blue. It’s fresh, summery, and looks adorable on him for photos or special occasions. My wife? Not so much. She immediately said “baby blue ugly” 😅😅 On the plus side: • Soft fabric – linen blend feels gentle and breathable on little skin, no itchiness or stiffness. • Nicely packaged – arrived with very little wrinkling (barely needed steaming), which is a win for linen. • Good fit for a toddler – true to size, easy to button, and the shorts/pants have adjustable waist for growing kids. • Looks sharp once on – the set gives that classic little gentleman vibe without feeling over the top. It’s a quality piece overall, just a classic case of “what one spouse loves, the other doesn’t” on the color. If sky blue works for your family (or you’re shopping solo like me 🤣), it’s a solid buy.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
