I have been posting about my beta version CPR reactor in another thread, where I've explained filling it with T.L.F. de-nitrating pellets, but now I'd like to share with y'all the story of the interaction of that reactor with the Tunze skimmer that had been my only filtration previously. (Except...

It came, very punctually from its EBay source. If you wish to know what it looks like running alone, check on Youtube.Many images available. It had decent documentation for a Beta unit, but in my LFS I could find only a Chemi-Pure medium for de-nitration which turned into a coal-dust mess...

Hi all - I had this idea about turning the mid section of my tiiny built-in sump into a primitive reactor. The feedback was that this would be ineffective as there would be no spinning or pummelling of the pellets. Which leaves me to ask y'all: What is the smallest reactor container made. I...

Bertie is back with another strange idea. I have this much re-formed Biocube 29, which now has in its middle section back sump a Tunze skimmer and a few rocks. What if I were to make the half of the section, which is now nothing but an empty plastic rectangle, into its own de-nitrator, by...

I'm thinking of buying a little shelf of acrylic or pvc or some plastic which I can glue to the plastic back of my tank to make a small area of shadow, both to shelter the fish and so I can grow something which doesn't want the heavy LED canopy lights. I'm sure there must be something available...

I know most people live on a public drain system, and dump their residue from water changes down the drain, but we have a septic tank, and that is not a workable solution to us. We also live in the woods, and have been dumping our used salt water along our 1/8 mile driveway. But I don't want...

Three times this past year I've had a titrate-style nitrate measurement kit start giving wrong signals - not suddenly off, but slowly becoming less accurate so that I wound up with a tank reading of 40 on the nitrate scale when I bought a new kit to test the one that was placidly giving me 5 or...

Hi! This is my first posting on the forum. I bought a Tunze Nano skimmer for my 29 gallon tank in December. It sits in the refugium, and the circulation pump comes after it in the flow. (I was told by Tunze that having it in the other order would lead to bubbles in the tank.) But I DO have...
