What is Plus?

Polyplab RF Plus is a water-stable mixture of liquid and solid coral foods that have been enriched with vitamins and minerals. Vibrant coral coloration results from regular use and is most noticeable for SPS corals. Additionally, unlike any other coral food, Plus has been engineered to be free of nitrates and phosphates.

Directions:

For every 25 total gallons of system volume, dose one drop daily of Plus. For optimum results, dose Plus when tank lights are turned off at night.

Composition & Analysis

PolypLab describe Plus as a water-stable mixture of liquid and solid coral foods, enriched with vitamins and minerals, and engineered to be free of nitrates and phosphates. That last part is the point of the product: on an ultra-low-nutrient system you can feed the corals without moving the two numbers you have spent months pulling down.

Beyond that, there is no ingredient list and no guaranteed analysis to give you. PolypLab publish no composition, no protein, fat or ash percentages, no vitamin schedule and no particle size for Plus — anywhere. We are not going to reconstruct one from what a coral food usually contains. If you need a declared analysis for a specific reason, ask us and we will put the question to the supplier.

Where it sits in the range: Plus is the food component of PolypLab's four-part System Reef-resh, alongside Genesis (a bacterial blend), Acids (amino acids) and Fuel (a carbon source). PolypLab's own position is that the four work best run together.

Feeding Guide

Dose: one drop per 25 US gallons (about 95 litres) of total system volume, daily. A 190-litre system takes two drops; a 400-litre system takes about four.

When: PolypLab are specific about this — dose Plus at night, once the tank lights are off. That is the opposite instruction to their Refuel, which goes in during the day. Corals feed at night, and a food dosed into a lit tank spends its window competing with photosynthesis.

Count system volume, not display volume. Sump, refugium and any external reactor volume all count towards the figure you are dosing against.

Our note, not PolypLab's: this is a suspension of solids in liquid and PolypLab publish no shake-before-use instruction. We would invert the bottle a few times before dosing anyway — if the solids have settled, the first drops out of a still bottle are not the same product as the last.

Start at the label rate and stay there for a few weeks before judging it. PolypLab position the visible result — coloration, most noticeably on SPS — as something that comes from regular use rather than from a heavy dose.

Pack Size

50 ml. That is the only size PolypLab make Plus in — their own store lists a single variant, SKU PL3, and there is no larger bottle. The same 50 ml bottle is the Plus component inside their four-part System Reef-resh kit, where Genesis, Plus and Acids are 50 ml each and Fuel is 500 ml.

We are not going to tell you how many drops are in it. PolypLab publish no drop volume and no bottle-life figure, and a drops-per-millilitre number varies with the dropper, the viscosity and how you hold it. What we can say is that at one drop per 95 litres per day, a single-tank hobbyist is buying this bottle for a long stretch rather than for a month.
