I have a Fluval Spec V (5 gallon) with a few plants....Java Fern, Anubius, and Water Sprite. I use root tabs and I started using the Aquarium Co-op Easy Green .50ml once a week to help out with the plants. All of a sudden, I have string like algae growing amongst the plants and some of the leaves of both the water sprite and Java Fern have a deep blue/green algae growing on some of their tips of the leaves. I do water changes 40% once a week. Any ideas on how to control the algae? Also my Water Sprite is not looking that great...looks like it is slowly dying. Appreciate any insights.
