Component 3in1 2000ml — Aquaforest All-in-One Balling Reef Dosing

Aquaforest Component 3in1 2,000 ml — all-in-one Balling economy large format

The Component 3in1 2,000 ml ships Aquaforest's simplified Balling recipe in a two-liter bottle, the economy format for established reef tanks with steady consumption. Same single Ca + KH + Mg + trace-elements solution as the 500 ml and 1,000 ml versions — only autonomy changes. The 2 L covers several months of operation on a 100-300 L reef without extra handling.

Each liter of 3in1 delivers 40,000 mg Ca, 1,900 mg Mg, and 5,800° KH per the official sheet. The 5 ml/100 L starting dose raises alkalinity by about 0.29 dKH — a useful reference to anticipate the effect of a dose increase.

Which tanks the 2 L fits

• Established 100-300 L reef tanks — stable Balling routine, predictable consumption.
• Handling-lean hobbyists — fewer bottle swaps, longer autonomy.
• Steady-growth LPS tanks — regular dose with no need for frequent adjustments.
• Multi-tank setups with moderate cumulative consumption — one bottle across several small volumes.

Official dosing

• Starting dose: 5 ml per 100 L of tank water per day.
• Maximum dose: 25 ml per 100 L per day.
• Measurable effect: 5 ml in 100 L = +0.29 dKH alkalinity.
• Testing: wait at least 5 h after dosing for accurate Ca and KH tests.
• Tuning: in 1-2 ml per 100 L steps, week over week.

Why choose Aquaforest at ReefSolution

• Component 3in1 1,000 ml — the mid-tier to try before the 2 L if the tank is smaller.
• Components 1+2+3+ 3×5 L — the switch to the classic Balling trio once consumption exceeds 25 ml/100 L/day.
• Magnesium Test Pro — the periodic Mg test to confirm 3in1 holds magnesium over time.

Frequently asked questions

How long does a 2 L bottle last on a 200 L tank?

At the 5 ml/100 L starting dose (10 ml/day on 200 L), the 2 L bottle covers 200 days (about 6.5 months). At an intermediate 15 ml/100 L (30 ml/day), it lasts about 66 days.

Is the 2 L cheaper per liter than the 1 L?

Usually yes — the per-liter price drops as the format grows. That's the main economic case for the large format once consumption justifies it.

Can I store the 2 L bottle for a long time after opening?

Yes — the content is stable at room temperature, out of direct light and tightly sealed. Aquaforest doesn't publish a post-opening shelf life, but 6-8 months of use raises no observed issue on tracked tanks.
