How to avoid Phytoplankton crashes

[acroman]

yeah, the dominant strain will always take over. the dominant strain, however will depend, to an extent on the culture conditions. (ie at temperature x, with light y, nanno will be dominant, however, at temperature z, chaeto will dominate)

 

[Kurt03]

chaeto? Theres not chaeto in my culture

I see what your saying though. So its usually 73-75 with a 15watt florescent strip light. anyone want to take a guess? or does it not matter a whole bunch? Whats the advantages to the diffrent types?

 

[snabss]

diff strains have diff nutritional values, thus suitable for diff breeding/feeding regiments. but mostly a mixture is used.

this link has some useful information about diff strains of phyto. i think nanno, tetr and iso are three strain used mainly in fish larvae feeding.

I recently restarted my 2g bottle of phyto a few days ago. I used RO/DI water this time just to see what would happen. 20ml of Miracle Grow, 4ml Kent's Essential Elements, and maybe 2oz of a previous phytoplankton culture.

It has been getting more green each day. The first day it was hardly opaque.

Yes, topping off would be a good idea.

I started mine from dt's, so what kind of phyto do i have??

listed on the bottle is
Nannochloropsis
Phaeodactylum tricornutum
and chlorella

Which most likely takes over in my culture?

I thought chlorella was a freshwater algae. Does it have a saltwater species?

 

[snabss]

i am using tap water right now for my culture medium (ofcourse with salt in it) and it seems to be working. i will try with some Ro water next time.

 

[ictoagsnstii]

ok, my disks came in (yay!) and i sterilized my saltwater in the microwave, and am going to cover the disk in that water. thats correct, right?

 

[snabss]

i would sterilize the tap water in the microwave first and then add salt to it and use that on the disk. but i guess the other way round would be ok too.

It is naturally. I know the largest producers of it are the Japanesse, and they've adapted it to brackish salinities.

Gresham, if I wanted to start a new culture using Phyto Feast, is there any reason it wouldn't work? I still have some of my own home-grown Nanochloropsus. I've used DT's in the past, but has anyone tried Phyto Feast? (Btw, it should have been called Phyto Pheast! :lol

 

[snabss]

isnt phyto feast dead algae?

The PF contentrate is prepped like our Istant Algae paste, and mixed together. THe Phyto-Feast Live, is well, alive

Stop on by, your in the same City

What makes you say that?

 

[GreshamH]

It's my line of work I work with several phycologists with many post docs in this field. I simply ask them :lol:

 

[snabss]

greshamH, are you in campbell? do you have a shop or business of your own? i havent met any other reefers in my city, though i am sure there are many

 

[Ixthys]

Fair enough

Tell them to read the article (quoted by Frank Hoff) by Maruyama and Nakamura (1986). ...unless of course you're working with those guys! JK

I'm sure they've read it. We sell Frank's book I'll try to get one of them to register and answer more in depth
