About this product
Seachem StressGuard comes in a 500 mL (17 fl. oz.) bottle, and the conditioner itself sits at a pH of 7.0. Aquarium pH stays where you set it, even when a heavy dose goes in, and a reef or planted tank holding invertebrates can take this product without trouble. By metric volume the bottle is about 503 ml.
Does it suit a reef or planted tank?
A reef aquarium or a planted aquarium that contains invertebrates is fine for StressGuard, so a tank with corals, plants and a clean-up crew does not need a separate product for this step. Each bottle carries 500 mL, or 17 fl. oz., which is the size to weigh against how much you dose per water change.
pH behaviour and tank compatibility
- The conditioner has a pH of 7.0, a value you can compare with the pH you keep your tank at.
- Aquarium pH is left untouched by this product, even at large doses, so a heavy dose does not push the reading up or down.
- Reef and planted aquariums holding invertebrates are listed as safe for this product.
