Water looks clearer/cleaner. No clouding/colour when added to tank water and has a nice mild smell. Easy to use and will last me a while because I only have a 9 litre tank. Fish are happy and healthy. Arrived quickly and well packed and sealed. Recommend. Review: Fab product ! - Purchased this for my fish tank as after setting up and it staying clean till the next water change, large amounts of dirt and algae started to build up over the acrylic, the decorative pieces, pebbles etc. Since a good clean up and using this, the tank and all of the contents have stayed much cleaner. No build up of dirt, cleaning is minimal, the water is clear and the fish are happy and healthy. It seems to work well with the filtration and it noticeably leaves the filter and ceramic media much cleaner too ! Price is great, dispatch fast. Instructions could be a little clearer but it’s fine. All in all a great product. I would recommend! ## Features - Contains one AQUARIAN Weekly Water Cleaner Aquarium Water Cleaner, 118 ml bottle - Helps keep aquariums clean and healthy and reduce maintenance - Contains live bacteria to destroy sludge in the gravel bed and helps to keep plants and glass clean - Adds beneficial bacteria for a healthy aquarium - Use weekly to maintain a clean, healthy aquarium - Note: The Aquarian range has two liquid products are listed on our website.

You can’t even overdose them if you accidentally pour too much in. **Q: Would you use this along side tap safe?** A: Yes. But i just bought tap safe and used that on its own rather than loads of solutions and works just as good :) **Q: When it says cap full does it just mean the lids on top of the bottle?** A: Yes just the lid but i used this and 6 of my fish died . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Weekly Cleaner *by N***H on 17 August 2025* So far so good.

All in all a great product. I would recommend! ### ⭐⭐⭐⭐ Good product, fiddly dosing *by K***H on 29 July 2025* Keeps tank water clearer between changes and helps reduce odour. Fish seem unaffected, which is always a good sign. Only downside is the cap isn’t great for dosing, needs a pipette or spoon to avoid spills. Good quality and value for money. ## Frequently Bought Together - AQUARIAN Weekly Cleaner Water Conditioner, 118 ml (Pack of 1) - AQUARIAN TAP WATER SAFE, Aquarium Water Conditioner, 118 ml Bottle,White - Aquarian Goldfish Food Flakes, 50g --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/82890383-aquarian-weekly-aquarium-cleaner-and-water-conditioner-118-ml-bottle](https://www.desertcart.us/products/82890383-aquarian-weekly-aquarium-cleaner-and-water-conditioner-118-ml-bottle) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-05*
