Modern Reef One-4Reef All in One Dosing Solution

Experience a super-concentrated, pure organic reef-keeping solution that delivers proportional consumption in one canister. Formulated with all essential trace elements found in natural seawater, organic micro-nutrients, and amino acids, this ready-to-use formula supports thriving, colorful corals and a stable reef aquarium. Highly concentrated (1L contains 50.160 mg/l calcium and 7.000 °dKH/l), it’s designed to work seamlessly with a complete Reef Keeping System, or as a standalone method, and is also compatible with calcium reactors.
Important! Organic dosing can significantly reduce nutrients via bacterial activity, which may lead to pale coloration or stagnation. Monitor NO3 and PO4 and dose N+ and P+ if needed, especially in low-nutrient systems. Consider this a form of carbon dosing and reduce or stop separate carbon sources when in use.
Benefits:
- All-in-one canister to supply essential reef needs (Complete Reef Food and Polypop still recommended)
- No accumulation of by-products like sodium or chloride
- Suitable for LPS, SPS, soft, and mixed reef aquariums
- Enhanced color, growth, and polyp extension
- More resistance against cyanobacteria and dinoflagellates
- Helps clean rocks and sand and maintain clear water
- Reduces excess nutrients like NO3 and PO4
- Ideal for manual or automatic dosing; space-saving setup
- Can act as a “saving-mode” with Balling or calcium reactors
- Unique proportional consumption formula in organic form
You can use it in 3 ways:
- Alone as a base reef-keeping system
- With a Reef Keeping System as “saving-mode”
- In reef aquariums with calcium reactors
Start with 4 ml per 100 liters, increasing by 2 ml per 100 liters every 2–4 days until KH and calcium stabilize. Use calcium as the dosage regulator; KH from organic Balling may take up to 2 days to show on test kits. Do not exceed 20 ml per 100 liters per day. For large systems, split dosing across multiple canisters/pumps.
Use as “saving-mode” to combine organic and inorganic Balling. Test KH and calcium during the first 2 weeks. Two options:
- RKS at 75% and organic solution at 25%
- RKS at 50% and organic solution at 50% (5 equal parts dosing)
Allow 5–10 minutes between each pump dose. A 5th dosing pump is recommended; if not available, combine KH1 and KH2 in one container and double the dose.
Reduce reactor capacity to 50%, then start with 2 ml per 100 liters daily. Adjust by 1 ml per 100 liters to maintain 7.2–8.5 dKH and 390–440 mg/l calcium. Benefits include lower CO2 usage, improved pH stability, cleaner substrate, clearer water, extended reactor maintenance, and ongoing supplementation of elements consumed by bacteria.

Reassuring to use an operator with tracked named-day delivery, exactly what you want when dealing with glass aquariums. Great range, great prices.

24hr delivery of a pallet, for a complete marine aquarium. And two days before Christmas. No picking errors, best pricing and then great service with hour slot from UPN Pallet Network. Impressive!

Nice searchable website, plenty of stock, reasonably priced next day delivery, well packaged. Slightly more detail would have been nice as I bought 32mm thinking that was the external diameter but I suspect most people buying these items would know that. :)

This was actually my first time ordering something from them wasn’t sure on how long I would get it said two days, but literally I ordered it and it came the next day. Packaging was amazing. Didn’t even pay next day delivery and I got the next day If you’re reading my review, give them a try. They don’t disappoint.

Such a great service. Bought a fish tank Ciano emotions 150 Pro and it's arrived very well packed just 2 days after purchase. After 2 weeks i had an issue with light power supply which has been replaced straight away after I reported that to customer service. They look afyer customers and always replied very quickly if you have any problem. Strongly recommended!!!
