Seachem Flourish Potassium

Seachem Flourish Potassium is a highly concentrated potassium supplement for planted aquariums that helps prevent potassium depletion and supports vigorous plant growth.

  • Potassium supplement for the planted aquarium
  • Highly concentrated (50,000 mg/L)
  • Does not contain phosphate or nitrate making it ideal for use with Flourish Nitrogen and Flourish Phosphorus

Seachem 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.

Why It's Different

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 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), and weak stems and roots.

HIGH waist, correct sizing, ok fabric...NOT SEE THRU!! Cool pants though!
Fit Type: 31" Inseam, Size: Medium, Color: Deep Khaki
If it's a few inches ABOVE my belly button, inseam is correct... but then MED is SUPER baggy in the butt (I have a small butt maybe?) WELL MADE! NOT see thru!! Fabric is kind of stiff, BUT because it's a linen blend, may be beneficial for less wrinkles? 😃 Probably improve if washed. Also tried the small, belly/butt area is better, but super high and a little tight on me. NO off gassing 👏👏👏 Super versatile (dress up or down) Good price.

70%linen, 30% cotton pants
Fit Type: 31" Inseam, Size: X-Large, Color: Khaki
Linen cotton blend, soft & not see through. I'm 5'4" & 157 lbs, ordered a XL size & they fit perfectly, just a but long. Took me 8-10 minutes to hem, & now they are my go-to summer pants! Elastic + drawstring waist & wide legs look very stylish. I'm very pleased, will probably order more in a different color. I love the natural linen color, but since I see fabric thickness will try in white since summers where I live are triple-digits. GREAT PANTS for the price!

These are so-so
Good fit (I’m 5’8”, 215 pounds, and got an XL), cool and light fabric. I wore them on a recent trip to Walt Disney World, and they held up pretty well. They do get wrinkled easily, though, and I was somewhat dismayed to find that the fabric pilled badly in the crotch area (see photo). This was after only one laundering and one vacation where I wore them maybe three days. 😒 I have a feeling that they won’t last for more than one summer season. I expected better for the money, honestly.

Read the size guide!
Fit Type: 31" Inseam, Size: Large, Color: Khaki
Got the light khaki Large. I am 5'7" and 180#'s. Loved the sturdy yet breathable material and the color. But too small. READ THE SIZE GUIDE! I didn't, and now I have to return and reorder. OK. Got the right size. Love 'em. Comfort and fit are great. Not crazy about having to line dry, but it's the price one pays for having natural fabrics.

RED & BLACK PANTS BLEED WHEN DRY AND WILL RUIN WHATEVER THEY TOUCH
Fit Type: 31" Inseam, Size: Medium, Color: Wine
These are very cute and flattering pants, but the first I wore them they turned everything they touched pink. The tops of my sneakers where they touched are now pink. The case of my cell phone that I slipped into my back pocket is now permanently pink. Apparently this is called “crocking” and occurs because there is a heavy excess of "unbound" dye on the surface of the fibers that was never properly rinsed or set during manufacturing. To fix this, I’ll have to go through a two-step process to strip away the excess surface dye and then chemically "lock" what remains. The needed specialized detergent and fixative products will cost another $20 (not to mention the pink sneakers and phone case). The process will take a couple of hours. I suspect the same dry bleeding would happen with other dark colors of these pants. Save yourself the hassle and buy a better, pricier pant in the first place. It’s very disappointing because they fit is great. They do stretch a size or two in the butt and thighs but the waist doesn’t stretch, which is good.
