Seachem Laboratories Reef Builder - 300 Grams Information

Product Manuals & Documentation

Use the Seachem Reef Builder Pet Store in your tank if you want to raise the carbonate alkalinity of your water. Tested and guaranteed, this liquid solution is ideally created to increase carbonate alkalinity in you reef tank. It will not directly affect pH but when used regularly for a long time, this product will stabilize it at 8.3. Carbonates are important in any marine aquarium like calcium. Using this product will help make your corals grow healthy and develop faster.

There will be better lush growth and skeleton formation. Using this solution properly will not reduce magnesium, strontium, calcium, or other minerals in the water. Unlike competing brands, the Seachem Reef Builder replaces the lost calcium, magnesium, and strontium during alkalinity treatment. Therefore, your tank will always be a well-balanced environment. This product is easy to use. You will have no problems with it because it has complete, detailed instructions for proper use. It can be used by an expert, advanced, or beginner aquarist. Any hobbyist can afford to buy this because it is very reasonably priced. Keep your corals and other inverts healthy by providing them a well-balanced water environment. Raise carbonate alkalinity with this inexpensive, efficient liquid solution. Give it a try today.

Seachem Reef Builder ™ raises carbonate alkalinity without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3. Carbonates and calcium are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Reef Builder™ will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Reef Builder™ and Reef Buffer™ may be used together. Use Reef Builder™ to raise carbonate alkalinity without affecting pH. Use Reef Buffer™ to raise carbonate alkalinity and pH.

Excellent!

Comments: I've been using this product for over 10 years now, and I recommend it and use it on ALL of my maintenance customer tanks. Won't overshoot alkalinity if dosed properly, and won't effect the PH, or Calcium levels. Grows Beautiful Coralline Algae!

Great!

Comments: I've always found this product to be a reliable way to maintain carbonate alkalinity at consistent levels. It's pricey and there are probably other products that will work but this one's the one I've been using for over six-years.

Comments: Used this for years. Mix a half cup with a liter of RODI water and make part B of 2 part. Do the same with Advantage Calcium for part A. Way cheapper than buying premade solutions. Also, Advantage Calcium doses magnesium to my tank too.

Comments: I have been using this product for over a year. My 150 gal. reef tended to drop to a dKH of 9; adding 2 tsp. of Reef Builder to a cup of water, mixing for 10 seconds, then adding to sump every 10 days keeps the dKH near 11.

Excellent!

Comments: I like Reef Builder because it helps keep the Kh at a high level and also keeps the Ph at 8.2-8.3 Without this (and Seachem Advantage Calcium), I would not be able to grow the Corraline aglae throughout my tank. Great product!

Excellent!

Comments: I have used Seachem Reef Builder for over two years and it is a great way to maintain alkalinity in a reef aquarium. I use the formula provided on the bottle and adjust my dosing accordingly. I also use the Seachem Advantage Calcium in conjuncture with this product, it makes a simple two-part recipe.

Excellent!

Comments: Reef Builder is a great product to rise and maintain alkalinity in a reef aquarium. I use it daily for this propose, combined with Reef Advantage as my two part dosing program. I dose Reef Builder in the morning and Reef Advantage in the evening, if needed. The big advantage with these two products is that they cause very little PH shifts if used as directed. Also, in my opinion, they are a great coralline algae booster.
