where did the hydroids come from?
I have no idea. They weren't there until a week or two after I added the pods.
A small pinch of spirulina powder in about 2-3oz. of water salt or fresh water is fine. Whip it like you are scrambling an egg with a plastic fork. Pour it around in the tank. Watch the video from page 1 post #8.
Yes I do.
It would depend on your tank temp to what the bottle is and salinity.
I have no water movement. They just need water. They are used to living in tide pools where there is no water movement, salinity risings, and blistering hot California sun. Tough little critters. Sitting in a tank with a stable condition for a few weeks aside of ammonia. This is heaven compared to what they go through in nature.
Ok but how do you keep the water from fouling?
I change about 85-90% of the water every 2 or 3 weeks. I have 3 airline tubes weighted down by a piece of rubble rock or a heavy frag plug elastic band around the end. I used frag gel glue around the outside of the tubes and pressed a piece of fine foam around them as a screen to siphon out the water and keep the pods in the tank. Usually I only replace enough water to get to the top of the rock in the tank. So about 3 gallons. When you start off. Keep the water level lower so the pods can find each other better with about 2 gallons and add 1 more gallon on the 3rd week when the population starts to grow. Then you will be were I am at doing a 3-4 gallon water change.
