Please fill out the webform on the Brightwell site and we will try to help you with dosing. We will need to know something about the plants you are keeping and the size of your aquarium. **Q: Does this increase phosphate levels?** A: Yes, that’s exactly what this is for. They include the calculation on the back to determine exactly how much to dose to reach your desired levels. Great product. **Q: Do you have to use this in conjunction with the NeoNitrate additiive that they also make?** A: It is not required. If you are just phosphate deficient just add the neophos if your ok with the nitrate. However, if you are also nitrate deficient then yes you can use together. But you don’t have to use them together if you don’t need to. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective! *by M***A on 8 September 2024* ### ⭐⭐⭐⭐⭐ Great for raising phosphate *by M***L on 29 June 2024* ### ⭐⭐⭐⭐⭐ Neophos *by A***O on 15 August 2025* ## Frequently Bought Together - Brightwell Aquatics - NeoPhos - Balanced Phosphorus Source for Phosphorus-Limited, Low-Nutrient Reef Aquaria - Aquarium Water Treatments, 67.6 fl oz - Brightwell Aquatics - Restor Liquid Coral Tissue Supplement - Fish Tank Reef Nutrition for Live Coral Growth Acceleration, Colour Vibrancy, & Restoration Additive - Saltwater Reef Supplies, 67.6 fl oz --- ## 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.co.uk/products/545707655-neophos-balanced-phosphorus-source-for-phosphorus-limited-low-nutrient-reef](https://www.desertcart.co.uk/products/545707655-neophos-balanced-phosphorus-source-for-phosphorus-limited-low-nutrient-reef) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
