What is the ideal temperature for Rotifers L-Type?

[CoralAndFishDepot]

I just keep them in 5g buckets, no heaters, at room temperature in my basement, which is about 68-70 degrees and they are doing ok but not as dense as I like. I read that they do better between 75-79 degrees. What temp do you keep your rotifers?

[Luis A M]

Your room temp is fine,but they will grow faster at 30C-86F.

[CoralAndFishDepot]

Can they really tolerate 86? What temp will give me the best density?

[Luis A M]

Sure they can.Temp will give you growing speed,food will give density.

I added a heater to one of my buckets o' rots in my chilly basement. I raised the temp up a few degrees a day, and they all died! The first time ever in years I crashed a bucket!

I ended up putting the other buckets on overturned buckets to get them off the cold cement. That was enough to increase the growth rate a little.

C'mon, spring! My husband won't let me turn the heat up! Our power bill is outrageous!

I've never boosted the temp in my rots but I boosted the temperatures in my brine shrimp cultures (four 25g rubbermaid pails) and found that while they grew a heck of a lot faster, my overall yields of the brine show a heck of a large decline.
I'm assuming the higher temperatures meant bacteria problems became more significant, lowering the yields.
Now I just do everything at room temperature which is 68°F in winter and 72 to 74°F in summer with the A/C on.
For the rotifers I've never needed them to grow faster as they do extremely well by feeding them a blended mix of spirulina powder and Algamac 3050 powdere, blended for two minutes in water. I add to the culture sparingly 3 times a day when I am using them and once a day when I don't need the rots but just maintain them.

I just added a small 50w heater to one of my 5g rotifer buckets and have it set to 77 degrees. I took a few sample densities before and will do again over the next few days to see what, if anything changes. Thanks again for all of the input.

Wow! I dont do half that stuff!

And I have both pods and rots together, for years...

they definitely grow faster with the higher temps. but ive never had a need for more than im producing now. i keep 2 5 gallon buckets going every once in a while 1 will crash and i just start another from the other bucket.
