Best Phytoplankton Culture vid I've seen. Very informative and good detail about using RO water (0.0 TDS) and how there's copper in fertilizer. Couple of questions, do you culture more than one type of phytoplankton? How long do you light your culture each day? You also never elaborated on how you can save a culture that's started to crash. You only mentioned feeding but nothing specific.
Thanks for the video :) One slight error I noticed - F/2 does contain copper, just in very small trace quantities (approx. 10 micrograms CuSO4 per litre of final medium). Also there's a good reason for F/2 to sometimes be shipped in weaker form - keeping certain components below 1% avoids it being classified as hazardous. Things you wouldn't know unless you looked in to making it ;)
You mentioned that if a culture crashes it starts to turn clear and you also mentioned that you can fix it with the F2 fertilizer how do you go about doing that do you just add F2 fertilizer after you filter it and then put it back in a clean vessel and put the air on it again?
Hi how often do you need to replenish the F2, and once you extract say half the phyto do you just replenish the saltwater and add 1ml of F2 Great and informative video
Do you reuse the rigid airline tubing or is it always a new piece when you start a new culture or split an old one? Been having slight issues with contamination but im not sure if it is because of that or because of outside particles being sent in from the airline tubing. All of mine are in 2L bottles capped off but there is obviously a small opening so air can leave.
Hi everyone, i consume marine phytoplankton as a supplement. I want to start to grow my own from the supply i have so i dont have to keep buying it. is f/2 formula safe for human consumption. as in if i feed this to my plankton, in turn is it safe for me? thanks
I have seen people using rubbing alcohol to sterilize. You can simply pour some in the empty bottle and shake it well. Then empty it and let the excess alcohol evaporate. Hope this helps!
