The best AQUARIUM POND ALGAE EATERS in 2024 - Detailed Product Descriptions

1. Seachem Clarity 500ml

By Seachem Store

Seachem Clarity 500ml

CLARIFIER: Clarity is the ultimate clarifier for both fresh and saltwater tanks. Clarity will help clear all types of clouding
REEF AND PLANT SAFE: Clarity contains an advanced polymeric flocculating agent that is both reef and plant safe.
MULTI-USE: Clarity is the only clarifier on the market that does it all. Clarity contains both precipitating and flocculating components in the same bottle that will clear and clean all types of cloudiness in all environments.
USE: When Clarity is added to the water, you will see a cloudy haze begin to form. This should be expected and means that Clarity is beginning to work. For optimal performance, Clarity must be used in conjunction with a fine mechanical filtration media such as filter floss.
DIRECTIONS: Use 1 capful (5 mL) for every 80 L (20 US gallons). Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears. If clouding persists, change your fine mechanical filtration media several times before dosing more clarity.

2. Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 10 ct

By Seachem Store

Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 10 ct

GROWTH TREATMENT: Seachem Flourish Tabs are growth stimulating tablets for plant roots which contain essential trace elements, amino acids, and vitamins.
VITAMINS: Seachem Flourish Tabs are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots.
NUTRIENTS: When inserted into the gravel, Seachem Flourish Tabs provide direct, time-released fertilization to the plants’ root zone. Nutrients are slowly made available through enzymatic action of the plants’ roots on the tabs.
TANK USE: Insert one Flourish Tab in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed, pushing each tablet midway into the gravel bed.
COMPLETE MAINTENANCE: For optimal plant growth, add new Flourish Tabs to the aquarium once every three to four. Seachem Flourish Tabs will not alter pH, however, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.

By Seachem Store

Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 500 ml

PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds, and introduce the already finished, structurally similar compounds.
TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.
SAFETY: Flourish Excel is completely safe for fish, however if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.
