Treat organic buildup and sludge in ponds, koi ponds, lakes and along pond shorelines. This is the 5 lb edition: open the premeasured 1 lb bags and apply the tablets.
Remove leaves and uneaten feed to limit new buildup.
Routine: 14 days. Heavy: 7.
Check conditions before deciding a dose is due.
Take bags → Open and spread → Let sink → Record
Have the dose table, a net and a phone or notebook ready. Remove reachable leaves and debris from a stable position. Check water temperature if possible.
1
Take the required bags
Use 1 bag for 6,000 sq ft; each bag is 1 lb (about 454 g). Confirm the bag count for your area before applying. No weighing is needed. Keep unused bags dry in the closed pail.
2
Open and spread the tablets
Open each bag and spread its tablets from safe, stable bank positions. Distribute them across the specified area, keep packaging out of the pond, and avoid emptying the whole dose in one spot.
3
Let the tablets sink
Let the tablets sink naturally. Do not premix them in water, bury them or enter the pond to place them; continue normal pond care afterward.
4
Record and plan your check
Record the date and bag count, and plan a check in 7 days. Before the next dose, use the schedule below to review conditions and count from your last actual application.
Follow-up: check before you apply
Routine care: every 14 days. Maintain an improved pond bottom and manage new organic deposits. Intensive care: every 7 days. Address existing accumulated organic debris; not every type of bottom sediment calls for intensive treatment.
Review buildup and water conditions first, then keep or change the plan. Count from the last actual application; never stack doses to catch up. This calendar starts at Day 1 and assumes no change of plan.

Choose the next interval first; apply only if due
Day 29 is a review point, not a mandatory dose or completion deadline. For example, after dosing on Day 22, switching to a 14-day interval on Day 29 puts the next possible dose on Day 36, subject to another check.
Pond care between applications
Use the stated dose and schedule whether or not you have a dedicated aerator. Aeration is recommended for best results.
Without an aerator
Remove reachable leaves and dead plant debris, and clear away uneaten feed. Keep part of the water surface free of floating plant mats and debris. Do not stir up the pond bottom or add extra product to make up for having no aerator.
If you have a fountain or pump
Keep existing fountains, waterfalls, circulation and filtration running as their instructions recommend. If you later add or restart an aerator, follow its startup instructions.
Review the same spots every 7 days
From the bank, compare debris and odor at 2 fixed spots and note how any fish are behaving. If you cannot see the bottom, record that. Check conditions and the time since your last application before dosing again.
How many bags do I use?
5 lb edition: dose per application
Treatment area (sq ft)
Premeasured bags
6,000
1 bag = 1 lb
30,000
5 bags = 5 lb
Each bag contains 1 lb (about 454 g) of tablets. No weighing is needed. For a rectangular area, length × width gives the area: 300 ft × 20 ft = 6,000 sq ft, which uses 1 bag.
Open the bags and spread the tablets across the area you calculated. Keep the empty bags out of the water. If the area is unclear or the dose does not match whole bags, contact us with your dimensions before applying.
Routine care: every 14 days. Heavy buildup: every 7 days. You do not automatically use the whole pail at every application.
If something is wrong, what next?
Check the pond’s condition before applying again.
Check water temperature
Best results when the water is above 50°F (10°C).
Recent use of other pond treatments
After using an algaecide, disinfectant or fish medication, check both sets of instructions for compatibility and spacing. If unsure, send us the product name and application date. Do not mix different treatments together. Check any UV settings against the relevant product and equipment instructions too.
Gasping fish or abnormal water conditions
Pause further applications, check the water, aeration and circulation, and promptly contact a pond-care professional. Muck treatment is for organic buildup; it does not replace emergency oxygen support, water-quality assessment or treatment of fish illness.
Still unsure after checking?
After checking dose, water temperature and incoming debris, send us photos and your application record if you still cannot judge the next step. Do not experiment with repeated extra doses.
Suitable use, storage and after-use care
Use the dose directions for this package size and the water area being treated.
Suitable use
For organic buildup and sludge in ponds, koi ponds, lakes and along pond shorelines. This 5 lb edition uses area-based dosing. For small fountains or birdbaths, choose the small-bottle product and its volume-based guide.
Storage
Keep unused bags sealed inside the closed pail in a cool, dry place. Protect them from moisture.
After use
Collect empty bags and close the pail. Pick up spilled tablets without raising dust, and follow the label and local requirements for unused product and packaging.
Take care during use
Apply from safe, stable positions on the bank; do not enter the water or wade into sediment to place tablets. Avoid breathing dust or getting the product in your eyes, and wash hands after handling. Keep the original package closed and out of children’s reach.
