## Overview

Red Sea NO3:PO4-X is a 1L liquid solution that biologically reduces nitrate and phosphate levels in marine aquariums through a unique carbon complex. It enables precise, monitored dosing to prevent nuisance algae and enhance coral coloration by optimizing symbiotic algae levels, all while maintaining beneficial micro-fauna. Reef-safe and BPA-free, it supports healthy coral growth and a balanced aquatic ecosystem.

## Description

NO3:PO4-X ALGAE MANAGEMENT A complete, reef-safe, controllable solution for nitrate & phosphate reduction NO3:PO4-X is the original, safest, most popular, and best solution that provides a full, reef-safe, controllable method for nitrate and phosphate reduction, thereby boosting coral growth and coloration in any reef or marine fish system. Unlike other methods, the monitored dosing of NO3:PO4-X biologically reduces both nitrate and phosphate, while enabling the fine control of their levels. This fine control allows gradual changes and guarantees accurate maintenance of algae nutrient levels required to safely reduce nuisance algae and bring the symbiotic zooxanthellae algae to the optimal levels needed for boosting coral growth and coloration. NO3:PO4-X is a unique complex of carbon substances and other organically bound elements that enhances the activity of nutrient reducing bacteria, which naturally exist in all marine aquariums. Each carbon source in the complex is utilized by different strains of microorganisms and together with the balanced ratio of enzymatic co-factors guarantee a complete and safe denitrification process (nitrate reduction) and phosphate reduction in the aquarium.

## Questions & Answers

**Q: Can this be diluted with rodi water?**
A: I know of several reef keeper who dilute with rodi water when using smaller doses, although I would contact Red Sea for the right mixture

**Q: I am running vinegar for nitrate reduction. How long do I need to stop the vinegar before I start this??**
A: Suggest you call Red Sea.  Their customer service with this product is helpful.  Alternatively, you can also send an email. I've used both methods in successfully communicating with them.

**Q: Does this take longer for large tanks? I have 150 gallon s with a 68 gallon sump.**
A: tank size does not matter I have 180, and I dose it with a dosser which is the best way to reduce nitrates, this stuff is excellent....it will take a while for the bacteria to form (should not be more than a month) , you will notice first a white film on your glass, once that starts the bacteria is growing and the white will disappear, the fish and snails love the bacteria.  Again it needs to be done daily and your nitrates can be either gone, or reduced down to nothing if you prefer to have just a small amount.   Again a dosser is the best method Jaebo cheap and works well under 60.00   Hope this helps

**Q: Can this be used in a freshwater aquarium?**
A: It is suggested to use for salt water aquarium
