Rotifers vs Amonia Question...

Postby CaliforniaClowns » Fri Sep 24, 2010 2:06 pm

Trying to control the amonia in my rots..

I've been finding trace amounts of amonia in my rotifers so I switched up a couple of things.

First - I increased bucket / water changes to 2x per week
Second - I added a seasoned sponge from one of the tanks.

This is in addition to the daily Prime dosing.

Also when I pull rots every night I'm removing at least a gallon of water and replacing that with fresh salt water.

I'm not using tank water and there is no detectable amonia in any of my tanks.

I'm kind of at a loss for what else to do. I do strain my rots through a 53 micron sieve and do my best not to transfer any of the rots water over but you will still get some no matter what.

As the saying goes..... the solution ot pollution is dilution......

What is teh overall volume of the tank teh rots are in? I have mine in 2 x 25L containers & I can quite happily let them go for 2 weeks without any water quality issues (I feed them IA).

I have soem chloramx here that I have on hand incase ammonia does become a problem but so far it has not, I usually do a 100% water change every 2 weeks on each container (1 one week, the other the next week).

What density do you have the rots at & what are you feeding them?

Hello Mike. When you say trace what ppm is that exactly. I never test mine for ammonia, when I see the density drop or the water gets to discolored for my liking I do a water change of 50-75%. I may be wrong but I don't think you will get 0 ammonia like a tank. There are too many rots and too little surface for bacteria to colonize. I would recommend going to rotifer.com. There is lots of good info there.

Thank you for the tips -

I am diluting - the rotifers are in a 5g bucket (x2)

The amonia reading I am getting is 0.05 ppm

I'm targeting 50/ml

I did have a hatch last night and still showed trace amounts of amonia - I was careful to wait and get any excess water out of the sieve. The larvae tank is still reading 0 amonia.

It's possible I'm being overly cautious. I had a string of bad luck with hatches and I'm trying not to take anything for granted.

Add some surface area to give bacteria a chance to colonise and convert the ammonia. 0.05 is not to much to worry about tho.
