# Intralabs Sodium Thiosulphate ST 1kg Crystals

Intralabs Sodium Thiosulphate ST is listed as crystals for aquarium and pool water dechlorination, with photographic processing also named as a use. The listing gives a treatment rate, but its 1kg title conflicts with a separate 500 Grams weight detail, so confirm the pack quantity before buying.

## At a glance

- The listing identifies the product as sodium thiosulphate crystals and claims 99% purity.
- Listed for dechlorinating aquarium and swimming-pool water, as well as photographic processing.
- The stated pond/aquarium directions say to dissolve the required amount in a bucket before pouring it around the pond.

## Pros

- A concentrated crystal format may suit buyers treating larger volumes of water, subject to confirming the pack size and dosing instructions.
- Customer feedback describes the dechlorinator as effective and notes that it goes a long way.

## Specifications

### Identity
- Brand: Intralabs
- Model: ST
### Product details
- Form: Crystals
- Weight listed: 500 Grams
- Target species: Fish
- Item type: Water Dechlorinator
- Liquid volume stated: 300000 Litres

## Before you buy

- Listing details are contradictory or inconsistent: the title says 1kg and the treatment claim refers to 1kg, while the item-weight field says 500 Grams. The liquid-volume field says 300000 Litres, and the feature separately claims 1kg treats around 300,000 litres. Confirm the pack quantity and applicable treatment guidance before purchase. The listing also gives a pond/aquarium rate of 5g per 1500 litres and describes 0.1g to 0.2g for 10 litres at 4ppm chlorine, so these instructions should not be treated as interchangeable without checking the water conditions.

## In the box

- Sodium Thiosulphate (Included)

## A good fit for

- Aquarium or pond keepers seeking a crystal dechlorinator, provided they verify the package weight and dose for their water.
- Photographic-processing users considering sodium thiosulphate for fixer-related use, as stated in the listing.

## Less suited to

- Buyers who need a confirmed 1kg pack or a single unambiguous dose without checking the listing details.

## Customer feedback

Customer feedback highlights perceived effectiveness and value, including comments that the product goes a long way. That may matter for recurring water treatment, but the listing's conflicting weight and treatment figures make it important to confirm the pack size and dose rather than assume a particular yield.
- Positive themes: Customers describe the dechlorinator as effective.
- Positive themes: Feedback mentions value for money and that the product goes a long way.

## Frequently asked questions

### What is this product listed for?
The listing names aquarium and swimming-pool water dechlorination and photographic processing. It does not establish that the supplied pack is suitable for every application, so check the intended use and directions.
### How much does the package contain?
The title says 1kg, but the item-weight detail says 500 Grams. The supplied listing does not resolve this discrepancy, so confirm the selected package before ordering.
### What dechlorination dose does the listing give?
It gives a pond/aquarium rate of 5g per 1500 litres and also states 0.1g to 0.2g for 10 litres at 4ppm chlorine. These are separate claims. Confirm the appropriate amount for your water and follow the product directions.
