As Michael said, the more the better, mainly as a planktonic food source. I have/had 6 in my 120g, but I never see them, not even at night, because of my flame hawk. If you a shrimp eater, like a flame hawk, it could harass them, eat them, whatever, so just be aware. I'm fairly sure the flame hawk has eaten a few of the smaller ones to be honest. I had a similar problem when I had cleaner shrimp in there...I rarely saw them.

Wow...that should work, unless the fish gets some air and clears that screen, but its not likely.

John, Can't see the pictures. You can always use eggcrate which can be found in the lighting section of lowes or home depot. Bob

It also helps to put masking tape over the area to be drilled. I usually use 2 layers of tape which seems to hold the acrylic well enough. I also do this when cutting acrylic that has had the backing removed.

tgallo, sure thing...send me an email at rfletcher922@earthlink.net or PM me here. Bob

I'm running two 20,000ks on the blueline eballasts over my 120g. I really like the color...white with bluish tint. I just replaced the bulbs with new 20,000ks and need to go through the burn in stage.

Glenn, Not a problem. I can get you some as well. Interested in trading an sps frag or two for some? Bob

Michael, Sure thing...let me know when you get back and are ready for them. Bob

Alberto, I'm doing it only for the good of my tank. Its really not worth the trouble to try and make a little profit. I'll be happy to trade some rotifers for an sps frag or two if someone wants a starter culture. If you are looking to purchase some try roti-pods. http://www.roti-pods.com/ . You can't beat their prices since it includes shipping. Shelf life is only 7-10 days. Bob

I just finished harvesting a bottle of rotifers tonight. If you set up several bottles so that you could get a full bottle or two every night, you should have no problem having enough for fry. I'm only using two bottles and I get a bottle to feed my tank every three days.

I've got a healthy, reproducing population in my tank. I got 6 individuals from another reefer and they have reproduced like crazy in my tank. We can work something out if you are interested. Bob

Its pretty easy to tell when they are ready for harvest. You can actually see them in significant numbers. I have them in two 2-liter bottles. After 3 days of feeding they are ready to harvest, so I put half a bottle of rotifers in one bottle and the other half in another bottle. I take a full bottle of ready phytoplankton (grown 7 days) and top off the rotifer bottles. After 3 days, the rotifers have cleared out the phytoplankton (bottle is less green than when you started) and are ready to harvest. I bought a 53-micron mesh collector that I pour the rotifers through. This removes all the water and nutrients down the drain. I then take the mesh collector and pour into into my tank. Basically, I'm following Flame*Angel 's (from ReefCentral) directions from her website. It describes growing phyto and rotifers in a simple, but effective manner. Here's the link: http://www.sjwilson.net/reef Bob

Michael, Glad to hear its going well with the cultures. Let me know when you are ready to start rotifers. I have a culture going now that is ready for harvest every 3 days. I'd be happy to trade you something for a 2 liter bottle full. One word of advice, get alot of bottles of phyto going. Right now, I have 6 bottles of phyto and 2 for rotifers going at one time and find that I could use another 6 bottles just to be able to feed both the rotifers and my tank. Its amazing how quickly they can wipe out a bottle of phyto. Bob

Michael, Those are both great articles. I'm currently doing well with nannochloropsis and have just started culturing rotifers using the methods described in the articles. Bob

I'm a paid member and can't see 'em.
