On the temperature

Supa's own guidance is specific that lower temperatures or highly alkaline water will slow how the block dissolves, and higher temperatures will speed it up — so the 3–4 day figure is a guide for their stated conditions, not a guarantee for every tank. Made in the UK.

Why we chose it

It's a proper stopgap rather than a scaled-down holiday block — the 3–4 day window matches a long weekend rather than a fortnight, so it's the right size decision for the trip rather than the nearest thing on the shelf. It's not suitable for marine tanks, which is worth knowing before you buy it for the wrong setup.

Full description

Fish left over a weekend are not actually at risk of starving — they can go far longer than most owners assume — but a tank with nobody watching it is still a tank nobody is watching, and a feeding block closes that gap without a timer or a helpful neighbour.

The block is designed to dissolve slowly, releasing food particles as it goes rather than all at once, and it is built to supplement rather than replace an established feeding routine. Supa's own guide is one block in a 45 litre (10 gallon) aquarium, sufficient for 10–15 average fish for 3–4 days, and they note the water temperature range it assumes is 20–25°C.

On the temperature. Supa's own guidance is specific that lower temperatures or highly alkaline water will slow how the block dissolves, and higher temperatures will speed it up — so the 3–4 day figure is a guide for their stated conditions, not a guarantee for every tank. Made in the UK.

Who it's for: freshwater cold water and tropical fish keepers going away for a long weekend, who want a stopgap feed rather than a full holiday-length solution.

Common questions

How long does one block last?

Supa's guide is 3–4 days for 10–15 average fish in a 45 litre (10 gallon) tank, assuming a water temperature of 20–25°C.

Can I use this in a marine tank?

No — it's stated as not suitable for marine tanks.

Does the water temperature matter?

Yes. Lower temperatures or highly alkaline water slow the dissolving, and higher temperatures speed it up, so the guide timing assumes the 20–25°C range.

What's the protein content?

40%, with 8% fat and 2% fibre.

Is this a full holiday feed or a top-up?

It's described as a supplementary source of food, designed for a weekend away rather than an extended holiday.
