Phosban and Carbon Reactor

I ordered the following

Half Gallon - 1.5 Pounds Premium ROX 0.8 Aquarium Carbon

1 Pound (453 Grams) Bulk GFO "Granular" Ferric Oxide

I guess these are higher quality? I think this is what I understood.

Rox carbon is their best. So you only need 1 1/4 cups wich one canister will hold. Then the other canister will be for gfo. I dont know if you got the high capacity gfo or not ( its the most expensive one ). If you did you only need 1 1/2 cups wich this canister will hold. Therefore youll only need 2 single or 1 dual unit. Run the gfo in the first section and the carbon in the second

OK I got the unit. I however am having a few issues here installing it. I have the dual unit and I got a maxijet 1200. I am new to maxijet as well.

I am assuming that one of the two white tubing that came with the dual unit will slide on top of the maxijet 1200 outlet line?
If that is correct it looks like it is not the same size tubing, unless I have to press really hard on it to slip it on.

Second thing is the control valve that came with it. I think I will have to cut a piece of the white tubing to attach the valve on the inlet side?

Third thing is that the containers for media, they are saying to leave the foam disk in the middle for the GFO.
Should I remove it, then add GFO half of what I need , then insert the foam and then add remaining GFO? If not will the GFO go through the foam disk?

The instructions on this thing are really horrible.
 
You want that foam disk higher than the gfo so the top can slightly tumble. So really you can just slide that disk all the way up put in gfo and screw on botton with foam and you should be good

Thanks Nick. I am thinking about putting the maxijet in the sump. However I need a U-push tubing fitting to run the tube out on a 90 degree angle.
If I do not use it then it will bend. Any ideas where I can get a U fitting?

I do not see the GFO tumble at all. I packed the carbon tight (filled the whole canister and screwed on the bottom with foam).

I filled GFO all the way up in the canister and left about an inch space on top. I could see empty space once I closed GFO canister.

Now once I conned it, I do not see any tumbling in the GFO. Did I overfill it? I adjusted the flow from full to medium to low but no change.

That's odd? I get tumbling with 2 units together and still have to throttle back.

Couple of checks that I can think of right now.
Do you have the pump attached to the left(IN) side of the unit? Is the ball valve on that side?

Did you pack the gfo? Not supposed to.

Is the maxijet clogged or sucking itself to the sump wall?


You do realize that when we talk tumble we are only looking for slight movement of the surface particles right? I do not think the problem is too much media because as stated earlier, I can fill all 4 of mine and still have to throttle back

I am not sure what we mean by "pack the GFO". I just poured it in. Then put the bottom cap on.
When I shake the filled container I can see/hear it move. SO I will say it is not packed, unlike carbon.

Yes, valve is on left. Maxijet is sucking fine..
 
it sounds fine. You want the GFO to be slightly moving at the surface...otherwise you're not pushing at water thru at all. It should not be bouncing around as then the media will just dissolve quickly thru friction.

Do you have a pic of the reactor?

Sunny take a look on top of the gfo canister and make sure the top above the elbow says in...Maybe it was accidentally assembled wrong and the flow is going in the opposite direction.

Nothing encouraging to update. The only thing I can say is that my water is cleaner/clearer. The algae is still going strong. I think stronger :mad:

It is getting frustrating now ...

Algae is not always easy to get rid off, clearer cleaner water is a start.

Keep doing your water changes, blowing the rocks clean to get rid of the detritus, and try to cut your feeding down as much as possible.

Algae isn't necessarily going to just disappear it will take a while, but if you continue to do the right things you should start to see improvement.
 
Good thing to know is when you use gfo, you use a certain amount per gallon to maintain low levels in your tank. If your starting with a higher level, then you should use more than the recommended amount. I started with 1.5 as much for the first few months then cut it back to the recommended amount. So if your tank is 100 gallons and you should use 1 cup per 100 gallons i would start with 1 1/2 cups. You said you have some algae now so your phos level is prob high. Id start with 1.5 times the recommended

Phosphate is between 0.3 and 0.5. I filled the whole canister I have. I am using 1.5 times.
Let's see how it goes from here. I know I am getting a LOT of algae on the glass each day.

hang in there. It takes time for the tank to mature before most of the nutrients are taken up. I felt like it took almost a year for me before the purple coralline really took over the tank. When you say algae on the glass - it sounds like it's just diatoms and not necessarily the hair algae or worse bryopsis.
