A lot IMO. I'd block off the pump area using 40µm screen.. The more surface area you can create for the mesh, the less you will have to clean it. I suggest making a 4" diameter structure using a semi rigid mesh (you can find this at HD, OSH, etc) and covering the in the 40µm mesh. You can use hot glue, or super glue, to seal the mesh. Any hole in the mesh larger the 40µm can create issues, so be careful.

perfect, now to fine the 40µm mesh

ok sorry for the dump questions. I found some 37micron mesh, will this work?

OK, sorry to keep confusing you lol. this is how I did it over the weekend before I got the answer about the pump, and Eric from Reeds called me back also a little while ago and said this way will work great also, so I am gonna give this a shot first. here are some pics to give you an idea of how it will be running.
pardon the mess. here is what it looks like outside the fridge
just a better angle of how far the hose sticks out, it is sticking out 1"
and a pic of how it's setup inside.

Yeah, that'll work. Polyester hold up better to bleach so if you can get that, I would go that route. Stainless steel is far more durable, but more $$$.
Ahh, OK. Eric and I were just talking about this. He taught me most I know, err, pretty much everything I know about rotifer culture, etc, so any advice from him should trump any I give

Trust me i take your advice greatly and thank you very much for all the help you give everyone.
The one main reason that had me thinking the screen would be a pain is because even when i strain 1 gal of culture water through my 53 micron seive it seems like it clogs up fast and you have to tap on it to get the water through. If i used a 40 micron screen to seperate the pump from the rotifers i am worried it will also get clogged fast and then the pump will run dry. Or maybe im just over thinking things lol

Thanks I just wanted you to know that bit as I learn stuff from Eric every day. With a PhD in phycology and something like 5 post docs, and real world experience, he's a walking encyclopedia. I'm honored to work with such a person
No, you are not over thinking it... you are being critical of the plan which IMO is a must in this hobby, and not enough do it.
The clogging issue is a real threat, and needs to be dealt with on a regular basis. You could probably get away cleaning it every few days... if you have enough surface area. You could also use the pump and bleed some of it off back through the screen (backflush)... and you can use the bubbles for aeration on the mesh wall to help keep it clear. There area few options, but none replace regular cleanings.
Our systems that have, and do, utilize flow through, get cleaned daily. We're pushing a lot more per mL, and feed a lot more, but even more small scale one I made years ago clogged up using 100µm.

It must be nice working with a great group of people, and to learn from someone like Eric is great. tell everyone there thanks for making great quality products.
Trust me, I loose plenty of sleep thinking of different stuff to make sure I have all bases covered and I do over think a lot of stuff, but like you say it can be a good thing.
I like that idea of using the pump as a way of back flushing the screen and or using the bubbler. very creative. it got my mind going again for if/when I do try that way

just thought I would give an update, it has been running about 3 days now and working great. the water stays a good green tinted color and now all I do every morning is wipe the sides down and change out 2 gal. out of the 8 gal. with NSW, takes all but 5 min a day to keep them nice and happy.
just wondering if there is any info on how many rotifers a certain size tank can handle at one time?

You can jam quite a bit into a tank. We run around 5K an mL here, but we've gone with greater densities. A typical home culture is running in the low hundreds. The CCS and be pushed to 5K an mL. Just up the feed and stay very on top of cleaning it.

has anyone noticed their RGcomplete go from the dark green color or a watery brownish color?
in what length of time?

about 2 months.

sent one to Eric with the CC to you (hopefully it goes to you as I used GreshamH@ and not just Gresham), as the voicemail I got from them didn't seem didn't seem to match with the way I have the setup running.

well, I am still doing the automatic feeding but switched back to using a bucket. the tank idea just doesn't work as good as hoped, I am guessing it is because of all the corners and it is hard to get the proper air into the areas.
