I use rotigrow plus ( have used complete) and roti green

I keep wanting to try live but its just not worth it as long as the pastes are kept well chilled

I love RGcomplete for rotifers. I love live Isochrysis for copepods. I culture Iso, and buy RG. Wouldn't live without either.

I use refrigerated concentrates because I am crap at culturing my own.

I use RG+ and RGreen Omega for my Clownfish, and trying it with Dottybacks too. I do use N-Rich PL Plus to enrich rotifers even though I know I don't "have to". I keep wanting to do a side by side comparison with my Clown larvae to see if there is a difference when using the N-Rich. I have a hunch that N-Rich helps with misbarring, but I keep forgetting to run one of the tanks without the enrichment.

Well the person who told me it, said it had to due with using up nutrients, but plenty of people add more F2 to ongoing cultures. I never took the time to really look at what he was saying as when I entered the company, I considered what he said to be accurate.... mistake.

He said there is no "peak nutrition" which makes sense :lol:

Now I'm on a mission to correct any use of that useless marketing point. It has no place in our company

Might it be true that if a hobbyist were to let their algae grow too long, so that it was approaching the end of the "stationary" phase, and nearing the "crash" phase, then it might have significantly less nutritional value than during the "exponential" phase, or at the start of the "stationary" phase of growth?

One free liter of RG+ to all that read this thread should make up for it. I can PM my address.

What causes nutrition to wax or wane?

No need to enrich copepods on any feed.

With rotifers, yes, if you are feeding either of those and just doing the typical MO species, no need to enrich. If you need to boost the fatty acid profile to match the need of the species being cultured, that is where N-Rich comes into play.

Something that has no been mentioned here is RMI concentrates are harvested at peak nutrition, its what we do. As a hobbyist, its harder to tell, or rather, gear your production, to match need vs peak nutrition.

Yea Ive looked at both the RG Complete and RG Plus for feeding cultures of rotifers. And also enriching them with the N-Rich.

With RGcomplete and RG Plus, there is no need to enrich for any of the species hobbyist breeders are dealing with when using those two. They are an all in one.

Good to know. So using either RG Complete or RG + is only product you need to feed rotifers or copepods for feeding?

So far this method has been doing really well for me with my cultures of rotifers, copepods, and brine shrimp.

I'm still a complete noob though lol.

lol Yea I'm a complete noob to breeding. I can tell you a lot about reef tanks, but just learning on the breeding side. I've cultured phyto in past to feed to tank but now seems to be easier ways to do things with the concentrated versions. I believe I will do a little of both to see which works best for me.

Thanks for your input too. I've been reading through your webpage very good info!

Thanks for your input! I think both my be better in long run. Do you have any experience with RG Plus?
