Review on 🐠 Enhance Your Nano Aquarium with Boyd Chemi-Pure Blue (5 Pack) by Kristin Bridges

This is a very handy way to keep some control over the concentration of chemicals, including troublesome phosphates. Phosphorus control is difficult as falling phosphate levels can be very problematic when algae are present in the aquarium. Since algae need and absorb phosphate, there is a risk that all algae will die off in a short time and pollute the aquarium if the phosphate content falls. Using small packs like this will help limit phosphate levels but will not cause drastic fluctuations. If you are starting out with very low phosphate levels this is great as it can be used as a buffer against small phosphate swings without changing the chemistry. significantly in a short time. Also suitable for small aquariums. I change the pack weekly or bi-weekly depending on how algae growth strikes me. Deducted one star because part of the packaging arrived torn and spilled all over the bag.
