my ray tank started producing very low levels of nitrites why??

so i dont get what the second photo is man.that pipe with the slits?? and are these pressurized.are those drums sealed and water is forced through them??

and the last photo dont understand ,the inlet is the pipe with the five pipes connected like a fan and whats the other pipe ,how does it work.

i have three of these drums at work i can take home.the lids are sealed on them how did you get yours off?? once you open them the lid doesnt go on sealed anymore??

No they are not pressurized
. the one with the slits i believe is the the return ...The five pipe fan like deal is his homemade air manifolds..This would be perfect for ya since you have three of these at work...Nice Reactors DB....

Pipe with slits is the output.... Slits to keep the media in the reactor. Looking at the outside of the reactor the bottom bulkhead is a drain, attatched to a ball valve to clean out the sediment in the bottom of the reactor. The top bulkead is that output with the slits.

No they are not pressurized. The clear hose you see on top of the barrels going dowwn in is the water feed. This runs down into the bottom of the reactor. The PVC that goes down into the barrel is the air. I just drilled holes in the PVC out towards the ends so the air follows the walls of the reactor. I tried bubble bars and that wasn't even close to boiling the media. I tried several different "fan ends", through trial and error I thought it seemed to boil best concentrating the air out towards the barrell walls.

Spot on!!!

Thank you for the compliment! I thought they turned out pretty nice for my 1st attemp at them. Not sure there's many more improvements that could be made to the final product. BUT if anyone sees something I'm all for improvements.

Each reactor has 3 cubic feet of K1 in it. The Chips are supposed to be mixed 4:1 I believe, so I will likely end up witth 5 cubic feet of media each (4 of K1 and 1 of the chips) BUT figured there's no point in adding till I have more then 3 rays in the 750......

I really think that 1 reactor would handle the bio load of every FW fish in my house.

That system also has 1500 pot scrubbies in a wet/dry AND 50 lbs of ceramic rings (not the cheap ones either lol).

You must have cut the tops off those barrels than .i have three here i can use but they are the type that the top must be cutt off

I cut a hole about 7" in diameter in the top to be able to put the media and bulkheads in. I then zip tied the cutout back into place. The water and air each go through the threaded caps on top. I wanted to cut as small of a hole as possible to keep it rigid, but after the first 3 were too small I lost it and got jiggy with it... Made a big hole.


You definetly don't need 3, but overkill is good. I'd just be worried that a poor water to media ratio might not yield the efficiency that a proper ratio would. Look at aquatic eco systems for an idea on guidlines as far as how much media to use for how many gallons, LPM of air and gph of water.
