Description

Reef Builder 300gReef Builder effectively increases carbonate alkalinity (KH) without causing an immediate change in pH levels. With consistent use over time, it tends to stabilize around pH 8. 3. When used according to the guidelines, Reef Builder will not reduce levels of calcium, magnesium, or strontium, which typically precipitate as alkalinity rises.

Reef Builder effectively increases carbonate alkalinity (KH) without causing an immediate change in pH levels. With consistent use over time, it tends to stabilize around pH 8.3. When used according to the guidelines, Reef Builder will not reduce levels of calcium, magnesium, or strontium, which typically precipitate as alkalinity rises.


KEY FEATURES:

  • Enhances carbonate alkalinity (KH) with little effect on pH
  • A unique combination of carbonate sources that won't lower pH, unlike other bicarbonate alternatives
  • Will not diminish calcium, magnesium, or strontium levels

DIRECTIONS:
Beginner
Administer 3g (1/2 level teaspoon) for every 150L (40 US gallons) two times a week. Mix in at least 250mL (1 cup) of freshwater. Monitor alkalinity every two weeks and modify the dosage or frequency as needed. For accurate measurements, utilize the Seachem Digital Spoon Scale.

Advanced
Measure alkalinity, then adhere to the dosage regimen outlined above until alkalinity reaches 3-6 meq/L (8-17 dKH). Each 3 g/150 L will increase alkalinity by approximately 0.25 meq/L. You can adjust the quantity or frequency, but do not exceed 12 g/150 L per day. After that, use as necessary to sustain alkalinity.

love it.
This filter fits a 2008 Lexus RX400h perfectly and gives the fresh, clean air. I recommend it.

Fits 2005 325xi
Size: 2002-2005 E46
Snapped perfectly into place. Zero play with the fit and hood hinge still just as accessible as oe grille. No trimming required. If you’re sick of snapping your grille back in every time you lift the hood, buy it! I also have the colored grill inserts and they snap on perfectly with no play. https://a.co/d/3F83eFx

Fit is perfect and these have a very nice glossy finish
Size: 2002-2005 E46
Fit is perfect and these have a very nice glossy finish, which looks much better than the matte finish. As others have said, the driver's side grill lacks a cut out where the hood latch pull handle swings out when you need to lift the hood (compare the driver's side grill with the existing grill to see location and size of the cut out). I was able to cut an opening within 10 minutes and I haven't had any problems opening the hood since the installation.
