Nitrite spike

I have since last Wed gotten a Nitrite spike, rising from less than .15 ppm to 3 ppm.  I think it may be due to over feeding, although I don't find much food residue on the bottom of the tank.  Not…Continue

I was planning 1:1 grow bed to fish tank.  Sounds like with catfish more like 2:1. I'll revise my plans get back to you. Thanks

How much grow bed will there be?  It is often more about the amount of filtration rather than the amount of fish tank.  for growing out channel catfish, I often like to have 20 gallons of grow bed and 10 gallons of fish tank per channel catfish but I tend to grow them fairly big.

Hi I'm just getting started got a small system using a 44 gal water tank and half barrel grow beds.  just got hold of 2 IBC totes.  thinking about using one for fish.  I'm in SW Oklahoma wanting to use catfish but wondering about how many to use in the tote?

I've gotten by without an O2 meter.  If you are just doing backyard AP you can probably manage without.  If you are trying to go commercial, then monitoring O2 becomes more of a concern if you do heavy stocking.

Roger TCL.  Thanks.  Note to self. . . add more air.  O2 meter would be nice to have but I've spent enough for a while.

When water temps get really warm, the water can't hold as much dissolved oxygen and if you keep feeding full tilt you may actually deplete the dissolved oxygen level below the safe point and the fish will eat less if that happens and you wind up with uneaten feed further depleting your dissolved oxygen levels.  Viscous circle.  So when it's really really hot, monitor feeding very carefully and don't be afraid to with hold a bit of food now and then or feed a bit less if the water quality seems at all questionable.

What is the reason for needing to reduce food as temp gets near 90F?

TCL Said:

but if it gets really hot you will probably need to reduce the feed as water temperatures near 90 F.

Hey Randall, the catfish are doing great! They've been through the cycling process and all appear healthy. They're eating more every day it seems. Thanks so much for the kickstarter, you were a huge help!

when I'm around enough to regurgitate it all for everyone.

Sorry I've been to busy to get through much of my e-mail let alone get onto the site much.
