Seachem Flourish Potassium

Flourish Potassium™ contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.

The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.

Directions

Use 1 capful (5 mL) for every 125 L (30 US gallons). This dose raises potassium by 2 mg/L. Repeat 2–3 times per week or as needed in response to signs of potassium deficiency in older leaves which include: chlorosis (yellowing), necrosis (death/browning), pinholes in leaves, and weak stems and roots.

Considerations: Repeat 2–3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.

 

A: About 50 mL.

A: No

A: Potassium is a major nutrient and I've seen a wide range of recommended values all with good success between 30 - 120 ppm. Our Equilibrium™, if used at the recommended dose, will raise potassium to 50 ppm. The recommended dose of Flourish Potassium™ will increase potassium levels by 2 mg/L. As of now we do not manufacture a potassium test kit but there are some on the market that are available. The rate that you are dosing Flourish Potassium™ is definitely acceptable as this dosing regimen, along with using Equilibrium at water exchanges, should maintain potassium levels around 50 ppm depending on rate of consumption by your plants.

Inexpensive walls.
Color: Grey, Size: 34" - 3 Panel, Color: Grey, Size: 34" - 3 Panel
We had a hot request for a workstation in the warehouse with some privacy. These have worked great. Easy to assemble. They are lightweight and stable. This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!

Claims to be non see through but you can, easy to assemble but instructions aren't good. Decent money value, quality is okay. Good fit, not very sturdy.
