Kathy 55g, opinions?

[Evansbr]

Hi Kathy,
I was looking thru your photo's and admiring your successes.
What do you feed your Rots? I've been trying to get away from live phyto but my Rots don't seem to make it,, trying to use IA but must be feeding to heavy as they all die about 2 days in. also Feeding the breeding stock, tried ORAGLOW soaked with selco and mysis. now the nests don't even hatch. what do you feed parent stock? I tried oraglow as they will all eat it like no tomorrow even when soaked with supplaments. Ideas for me?
I hope to someday have even half your success would make me real happy like I accomplished something... I've had 2 live out of about 5 nests tried.

Was she banned too..or just moved to another forum?

 

[Evansbr]

what happened? I really valued her input. do you know if she moved boards? thanks for the help.

Hi

So whats your problem with the rots? what salinity and temp is it at?

And the fish you are cultureing are clownfish?

Yes, she has moved along with many others....

Don't wana say to much and get in trouble here, but...

 

[Evansbr]

The Rots are at 1.017 for salinity and I have tried room temp, so about 65. and have tried heaters to keep them at 80. I think I am overfeeding the Instant Algae, I can keep them alive on live phyto but wanted to try something more convenient as I also have 3 pairs of parrots I'm trying to breed and have alot less time. yes, I have three pairs of clowns, osc. true percs, and gold banded maroons that all are laying nests regularly.

I can help you, but I need to know more:

What IA product are you using (Rotifer Diet, Nanno3600,etc)
How large is your culture vessal?
Whats you rotifer concentration ( X amount per ML)?
How much IA are you feeding?
How often are you feeding?
Are you using any ammonia control?
Are you doing batch harvest or continual harvest?

I'd get your temp up to the mid to high 70's (f). I find the lower temps make for a very thin culture.

Some excellent info on this page:

You mean FW or the birds?Rots is out of question with any of them

If she doesn't respond, that is by her choice.

As gresham said up the temp of the rots, this will get them turning over faster, i find makes them more stable.

I havent been able to over feed mine on IA.

I have large strain rots going for months (batch culture) and I use nothing but IA. An aquaculture facitlity near me shut down their whole algae room because they now also use IA. These guys feed 8 million artemia nauplii a day, I can't imagine how many rots they go through. Check you water quality, and don't overdose the IA, you can add a couple of smaller additions a day of IA if you think you are overdoing it. IA does affect water quality, and not in a good way, but I couldn't dream of rots without it!

I am using 2 5-gallon tanks, with a heater in each and rigid tubing for air to circulate, no airstone. using instant nanno, does have food grade glycerin.. does that matter? doesn't say 3600 or anything on it. I feed twice a day and use an ammonia badge to watch for ammonia, they seem to die before the badge shows anything. I feed till there is a green tint where it is hard to see the heater on the bottom of a 5 gallon tank.

There is no reason to try to reach ultra high rots density.Just a squirt of IA when the water clears and it keeps running without trouble for a long time.

THe phytoplankton mixes Brine Shrimp Direct sells are done specially for them. We just supply the algae and they mix it up themselves with their own special formula.

I don't have any experience using nanno w/ glycerin for culturing rotifers, so I don't know what to say I don't think it should be much different then our IA feeds though.

I used to have problems with my rots not being dense enough and crashing every so often. I started dosing more heavily on the rots with IA and haven't had a problem since.

Sometimes it isn't that your overfeeding IA its that you could be underfeeding it. If you got a good bit a gunk on the bottom stir it up and wait about 10 minutes.

 

[David Thomson]

I actually have had BIG problems with overdosing IA. I too tried to dose until the water was green, and would get the same results as you, with the number of rots dropping. I now dose until the water just looks cloudy. About 1 ml of IA per gallon of culture water with a "good" density of rots going.

I personally would NOT use the IA with glycerin. From my understanding the glycerin causes excessive bacteria to grow, which can actually kill the rotifers. I used it before, and the cultures were very easly crashed.

 

[Evansbr]

Thanks for all the help/ input everyone,, can someone direct me to exactly what IA they are using and getting good Rot results??
And I guess my dosing isn't the most scientific, I run a water bottle full of RO/DI water, add a couple drops of IA and shake to mix... actual cell density of what I'm feeding rots?? no idea. When I was using live nanno it was no problem.. now cant seem to get it right.

IA=brand name.NAN paste by Reed.One (ice)cube in a one quart pitcher,kept in the fridge.
