    Bleach or Boil 150+ lb of LR?

    I had the most horrible HA problem in a 5 year old tank. No mater what I did I could not get on top of it. The tank is a 210g. My solution was to use 1 gallon of Clorox in the system. The problem turned white before I finished poring. I removed the rock and let it dry out for a week. I then...

    Swirl Steins with Koralia 4 Mods

    I cut them from 1/8 inch acrylic. Then drilled a hole where the center of the cross would be. I used a small round metal gouging bit to take the arms away from the center hole. It takes about 5 minutes

    Swirl Steins with Koralia 4 Mods

    No, and I am very happy with the motors I have. I have heard that they have low torque. The Koralia 4 mods are heavy and push against the down tube, a bunch of torque is needed to move them.

    Swirl Steins with Koralia 4 Mods

    For the last couple of days I have been having trouble with the left Swirl. I keep breaking the ring around the down tube. The problem was the pumps are putting allot of force on the down tube which is causing down tube to press on the sides of the bushings, the parts that are glued to the box...

    vodka dosing

    I have never had a problem reducing nitrates. I have used calupera and done fine.

    vodka dosing

    I understand you, It was my understanding that the bacteria that we need to remove nitrate in a gas form are anaerobic. The best place for these bacteria is in a no to low oxygen environment. This would be in a deep sand bed or plenum substrate. I am unsure how rock performs as a anaerobic...

    vodka dosing

    Am I missing something? I thought it went like this Ammonia, Nitrite then the less toxic Nitrate. I went through an ammonia spike then a nitrite spike, both are at 0 now, and then ended with 20 ppm nitrate. I have not had a visible spike of ammonia or nitrite since I added the perculas. As I add...

    vodka dosing

    No the tank is finished cycling. I assume the high nitrate is from the live rock I put back into the tank before cycling. As mentioned I used shrimp to cycle the tank and that dieing matter will produce nitrate also, I would think.

    vodka dosing

    I have recently nuked a 210g tank. The reason was a HA out break that I could not get on top of. The tank was in its 5 year when this happened. I did take about 60% of the rock out (200 lbs) and put it in other tanks. I refilled my tank with 100% RO/Di water and put most of the rock back in the...

    Swirl Steins with Koralia 4 Mods

    Finding the parts was not that difficult. The motors came from eBay, the rest from Home Depot and a hobby store. The boxes are a standard out door electrical box and the rest of the pvc was found in the same isle. The screws came from the hardware isle. I guess the acrylic rod was somewhat...

    Swirl Steins with Koralia 4 Mods

    I gave it my best shot at video; it is grainy and just looks bad. One thing you will get some idea of how they move. Here is the link. David http://s275.photobucket.com/albums/jj290/dngspot/?action=view&current=DSCF0001.flv

    Swirl Steins with Koralia 4 Mods

    …Yea, the flow it pretty incredible. I had AC 70 mods pointed at each other, there is no comparison. An Oceans Motion Squirt does not seem as random either. Pros No drilling my tank, can be removed easily, two small cheap pumps doing the job of a large expensive pump. Cons Two pumps hanging down...

    Swirl Steins with Koralia 4 Mods

    I used a dremmel with a sanding barrel and cut off wheel. I also used various drills. To cut the pvc is used a cut off saw but, a hack saw or pvc cutter would work.

    Swirl Steins with Koralia 4 Mods

    I have had these running for just over 24 hours and the flow is terrific. The pumps on the end of the Swirl Steins are a set of mod’ed Koralia 4’s, I am way impressed on their flow alone. I have the complete build thread at my local site. They are inspired from an old thread on RC. The build...
