## Description

Product Description Seachem PhosGuard 1L Directions Can generate heat when first contact with water. Pre-moisten by adding a double volume of fresh water followed by a rinse. For best results, PhosGuard should be rinsed before use and placed so that water flow through it is maximized, but not so that it falls against itself in flow. It can be used in a canister filter, media chamber, box filter or any high flow area of a trickle filter. The use of a filter bag is recommended. Use 3 oz (1/3 cups) for any 200L salt water or 400L of fresh water. Box Contains water treatment

## Questions & Answers

**Q: Does this remove brown algae?**
A: I use this product by adding it to the final stage of my filter. I monitor water parameters in my tank weekly including phosphate and change the PhosGuard roughly every three months or if the phosphate level starts to rise. My aquarium has plants and I add plant food daily plus I have CO2 injection. The tank has LED lighting which ramp up, on full for around six hours then ramp down. With this regime I do not get algae issues any more, plants are healthy and the fish seem happy.

**Q: Can i just leave it in the tank instead of inside the filter**
A: I do when it is required as I do not have a filter.

**Q: Can this be used in the fluval u3 filter thanks**
A: I used it to clean up my fluval fx6 which was badly contaminated with algae but it needed a massive clean out a few days later to remove all the dead algae from the filters and pipes that was in the tank and filter system

**Q: Does this come with a net?**
A: No it doesn't come with a net. You have to buy one separately

### ⭐⭐⭐⭐ Keeps diatoms at bay but does not rid you of them.
*by D***N on 20 September 2022*

I bought this to get rid of diatoms in my fish tank. When I used it, it would keep the diatoms from coming back but as soon as I removed the product they would take over again.
