Comments: I bought this and 4 other brands in bags or 6kg buckets to do a head to head for culturing various species of algae. I’ve built a concept system to culture the aloricate ciliate O. marina, other species of heterotrophic protistan and the ciliate algae predator species which accumulate dimethylsulfoniopropionate (DMSP) from the various algae I feed them like: CCMP1320 Dunaliella, CCMP1316 Chaetoceros muelleri (Once called gracilis or Chagra), Haematococcus pluvialis, common Isochrysis galbana (T-iso or and C-iso Turks and Caicos strain), Monochrysis lutherii (commonly called Pavlova), CCMP525 Nannochloropsis oculata, Rhodomonas sp. (8 strains CCMP 322, 760, 763, 766, 767, 768, 1319, 2005), Spirulina Platensis, Synechococcus, Thallassiosira weisflogii, excreta. Some hetrotrophs such as Artemia slina, ciliate algae predator species such as Oxyrrhis marina (5 strains CCMP 604, 605, 1739, 1788, 1795), and calanoid copepods, especially Acartia tonsa.
For each of these latten binomials and Bigelow Laboratory Provasoli-Guillard numbers you can think $50 to $125 each. So, a very good salt mix was very important from the very beginning. I wanted a good brand and I found it in H2Ocean Pro+. What I found with this H2Ocean Pro+ is that you can useit in tap water to make culture medium as long as you keep the salinity below normal seawater without the formation of calcium carbonate precipitates. In other words, tap water already has a lot of calcium in it and a lot of phosphates too. If I were to overload the water, all the good stuff will just let go fall right out as deionized sand. The high calcium and phosphate content being why I like to use tap water for culturing algae; that it’s clean and cheep doesn’t hurt any either. H2Ocean Pro+ is for small volumes like aquaria and stock cultures better than NSW. Still I would rather D-D Aquarium Systems follow Seachems’ lead and demonstrate potential of hydrogen with this product at a full 8.4 for aquarium RODI.
Yes, I would recommend this product to my friends.
