I have some extra phyto from my culture that I have going. 16oz - $15 (shipping $10) 35oz - $25 (shipping $10) 70oz - $50 (free shipping) Shipping will be done through USPS 2-3 day. I ship extremely fast too when I do have available phyto. Orders placed and payment received before 2PM CST will ship same day (barring any unforeseen circumstances), after 2PM CST the next day. I also can do custom orders too as long as I have enough available for myself. Just send me a PM and we can discuss. It is dark green. Keeps my pod population pretty high in my DT and my water quality pretty darn good. Culture started with: Tetraselmis, Nannochloropsis, Isochrysis, Pavlova,Thalassiosira weissflogii, Synechococcus (a good mixture for all your needs) Check out this video of the pod explosion: Just thought I post a pic of Xentrader since it isn't really as visible as it should be: You can check out more feedback on my Xentrader: https://www.reef2reef.com/xentrader/mitch91175.38897/?page=1#feedback-14240 FAQ: Q - How long will the phytoplankton last? A - Phytoplankton will last up to 6 months being refrigerated and shaken to keep the cells from settling to the bottom of the container. Mine is very dense so I recommend shaking at least 2 times a week (easily done with as many times as you get something from the fridge ) Q - How much do I need to feed and how frequently? A - There isn't a set amount that you have to feed. I personally feed my 240g a cup daily and haven't noticed any adverse affects at all. Every situation is different so you can start out slow then going from there. I know that my Aussie spider sponge absolutely love it when I cast feed my tank. I also notice my SPS have greater extension as well.
