The HTH Ultimate Algae Guard is the one that is added every 90 days, it is a copper based algaecide.
The HTH® Algae Guard10 quickly kills and prevents green algae so you can get back to swimming as soon as possible. Use regularly for maximum effectiveness. The non-foaming algaecide works to kill algae spores and prevent regrowth.
Algaecide will kill the algae and mold affecting your pool water, but it is best used as an algae preventative. While it does not change the pH balance of your pool water, it will keep algae from growing and work with your chlorine sanitizer to keep those levels balanced.
Grab a brush and some baking soda. Bicarbonate, the active ingredient in baking soda, is an effective spot treatment to help kill the algae and loosen it from the wall. Make sure you really get every last particle free; black algae has particularly long and stubborn roots which makes it a persistent strand.
HTH® Algae Guard 10 is formulated to quickly kill and prevent green algae.
It is best to wait 30 minutes after adding it to your pool. We recommend waiting at least 15 minutes to swim after adding algaecide to your swimming pool. Most algaecides are perfectly safe to swim with. It is not recommended to swim with flocculent in your pool as it will reduce its effectiveness.
It took two days but it was completely gone. Not a trace. I would so recommend this product.
Green Algae
It can grow both on the pool surface, resembling a green, slimy stain, and also suspended in the pool water, causing the water to appear to have a green tint. In severe cases, the algae is concentrated enough so that it is impossible to see the pool bottom, or even the steps.
Basically, an algaecide is simply a substance that can kill or mitigate algae, often utilizing copper sulfate or chelated copper. Copper is effective because it basically attaches itself to the algae in your pond and prevents photosynthesis, which causes the algae to die.
Fill the pantyhose or sock with 1 cup of finely ground cornmeal. Use 1 cup of cornmeal for every 100 square feet of pond. Use more than one stocking if your pond is large. Tie-off the top of the pantyhose.
While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
The presence of too much algaecide can lead to a foamy pool water. Small bubbles will begin to be produced as the water is pushed through the return jet and back into the pool. Do not confuse these bubbles and foam with another common problem, which is air in your pool lines.
Algaecide should be added to your pool water on a weekly basis. Preventing algae is the key to fun in your pool. Algaecides act as a backup to your normal sanitization program and prevent algae from starting and growing in the pool. Algaecide should be added after every shock treatment.
Regular algaecides do not contain copper, but rather quaternary ammonium compounds, also known as "quats" or "polyquats." These compounds are safe for immediate swimming. Use of too much algaecide may cause slight eye or skin irritation, so always be sure to follow the manufacturer's instructions.
The algaecide in the kit can cause some foam if there is no algae in the pool to destroy – it lingers around with nothing to kill. Spring time algaecides use surfactants to work and these molecules can react with agitation to cause froth.
Green PondFx is the safest, most effective algaecide on the market for backyard ponds, but caution must be used when applying it during warm summer weather!
If algae grow on the leaves and stems of your aquarium plants, create a routine of cleaning them regularly. Using a solution of 5-10% bleach, dip the plants for a few minutes as needed to destroy the algae. Make sure they are thoroughly rinsed because bleach can kill your fish. Invest in a filter.
To get rid of algae in a pond, try planting more aquatic plants in your pond, like lily pads, cattails, or watercress, which will absorb the nutrients that algae needs to grow. You can also throw a small bale of barley straw into your pond, which will slowly kill any algae over the course of a few weeks while it rots.
Use a vacuum or backwash the pool to remove the dead algae. Apply a mustard algaecide following the label directions. Allow the water to circulate for 24 hours. Use a pool vacuum or backwash the pool again to remove the remaining dead algae.
Pool algae can be caused by poor filtration, out-of-balance water, low or inconsistent chlorine levels, or poor water circulation. Green, dark green, yellowish green and blue-green algae are the most common. Green algae are slimy.
Winter Pool Algaecide is highly effective at preventing all forms of algae. Polymer pool algaecide stays strong all winter providing dependable control of algae growth throughout the winter season. Unique winterizing algaecide is specifically formulated to fight cold weather algae for up to 5 months in a covered pool.
Registered algaecides include copper sulfate, copper chelates (ethanolamines, ethylene diamines, triethanolamines, triethanolamine + ethylene diamine, and copper citrate/gluconate), endothall (as the mono (N,N-dimethylalkylamine) salt), and formulations containing the active ingredient sodium carbonate peroxyhydrate.
Many algaecides are copper-based—either made of copper sulfate or copper chelates, which are chemical compounds with a metal as the central atom. A few registered algaecides instead use the herbicide endothall or sodium carbonate peroxyhydrate.
