New Life Spectrum Probiotix Large 600g — Probiotic sinking pellets for large fish in a mid-sized refill pack
Once a big-fish tank has settled on a staple food, a 150 g tub starts to feel like a weekly chore. New Life Spectrum Probiotix Large 600g (SKU: 102603) is the 600 g pack of New Life Spectrum’s probiotic-fortified sinking pellet in the large size, 3 to 3.5 mm. It is meant as a daily diet rather than a treat: the recipe is built on whole Antarctic krill, giant squid and menhaden, and it carries live Bacillus and Pediococcus cultures that the maker says help fish absorb more of what they eat and put out less waste. Four times the 150 g pack, it suits one or two large tanks, or a handful of mid-sized cichlids fed twice a day through the season.
The ingredient list continues with omega-3 fish oil, whole wheat flour, bentonite clay and sea salt, then ulva, chlorella, wakame, kelp and spirulina, with garlic and ginger. Colour-supporting pigments come from astaxanthin, marigold, capsanthin and zeaxanthin, and vitamin C is supplied as L-ascorbyl-2-polyphosphate. Guaranteed analysis is crude protein 39% minimum, crude fat 9% minimum, crude fibre 8% maximum, moisture 10% maximum and ash 10% maximum. The cultures are listed at a minimum of 3 million viable cells per gram. Because the pellets are large and dense, they sink steadily, so they suit fish that feed in the lower half of the tank as well as those that rise to take them on the way down.
Usage & Application
When to Use
- Established large-fish tanks: A staple that has already been tested and is worth buying in volume.
- Cichlid and catfish collections: Several hungry mouths sharing one daily feed.
- Mixed freshwater and marine households: The listing describes the food as suitable for both.
- Refilling a feeder jar: Decant from the 600 g pack into a smaller tub for daily use.
Feeding Guide
- Twice daily: Feed an amount the fish eat within one to two minutes.
- Weigh by appetite: Reduce the portion if pellets are reaching the substrate uneaten.
- Decant small: Keep a week of food in a daily tub and the rest sealed.
- Store cool and dry: Reseal the pack after each fill, away from heat and humidity.
