Is the chamber recieving direct light from the display or a refugium? If you shade it somewhat it should not grow algae in there..


ETA: I wouldn't black it out.. but keeping a direct light source off the reactor should prevent any algea from growing.
 
It has at least 2 diff types of algae in it, that i can see.. it gets indirect light from my prop tanks..but the algae is the same thats in my prop tanks on my corals.. l
ike Broiposys and hair..
either way question still remains.. i need to know what the recommend cleaning of the fluidized reactor.. blocking it from the light is a possibility, should i completely black it out? wrap black plastic mostly around it?
 
Is the algea just on the walls of the reactor or on the pellets themselves?

If it was just on the walls of the reactor them if it were my tank I'd just cut the light back so the algea would die off.. That way I wouldn't have to disturb the pellets in the reactor.

Sounds like an established tank with a fair amount of PO4 in reserve? If you are still getting that much algea in your tanks then you might need to battle it additionally with GFO for a while... Bryopsis by raising your magneseum.

Its in the reactor.

I am running 2 Duel BRS reactors each with a chamber 3/4 full of GFO (Regular and some Hi Cap Gfo) the 2nd chamber is carbon)P04 usually test under0.0

Mag is 1500+ using Kent Tech M
 
Yeah.. fighting the algea in the reactor might be simplest via light deprivation. I dont think the benficial bacteria we are trying to host in there need much light at all, but I am not sure what effect a complete blackout might have. Most run thier reactirs inside an enclosed stand.. so close to blackout light levels should be OK.

Standard drill with the algae.. if you have live algae in the tank then your tests are not going to be able to pick up much of a PO4 reading unless there is a very large reserve of it in the tank.

Most PO4 tests are practically useless if there is active algea in the tank. Where they can come in handy is when running GFO so you can campare the effluent output of GFO reactor against the display tank reading.. if the reactor output is lower then you know the GFO is still working.. if it is the same as the display then it is time to replace the media.

What are your nitrates currently mesauring at?
 
Here's a video of my pellets in a TLF550. My problem is that as you can see in the video, only one small section is actually tumbleing. the rest are not. I can only attribute it to there being too little flow. It's currently being run (and my skimmer too) by a MaxJet1200, and from what I can gather the 295 GPH is simply not enough. So what is the next size up (affordable please) pump that I could fit in a similar space? Any ideas?

Check out the "EHEIM 1250Water Pump - 317 gph" it will get you the tumbling your looking for:hammer:
 
is it around the same size as a maxjet 1200? And I'm assuming it's fully submersable? I'm only asking cause I have limited space.
 
I used a submersible pump called Quiet One 3000 which pushes about 780 gph if unrestricted for my 750ml BP in a NextReef MR1 reactor. I have to dial it down quite a bit. Here is a video showing the BP tumbling. The pump is about $50 from Drs. F&S.

Hey I use the Quite One 3000 to return the water from my sump/fuge back to my 75 g display and find it to be quite awesome.
 
Here is a video of the NP-reducing biopellets in my two-chamber DIY upflow pellets reactor. I've had the reactor for phosban and active carbon media before but right now its only running the bio-pellets. Maybe a bit too stormy right now.

good grief that thing looks huge, what size tank is it for? As far as movement it does seem a bit on the strong side...but as long as the pellets are not being swept up and out the top then I think you are fine. But if you need to them maybe just add a ball valve and throttle it back.
 
My Phosban 550 reactor internal pipes are not large enough to run 1l of pellets. I now have a Eheim 1250 pump on it and the top of the pellets just turnover at full tilt so it must be the reactor pipework that is the restricting component. We cannot get Next Reef stuff in the UK - can anyone suggest a reactor for 1-2l of biopellets that has sufficient pipe work for a good turnover?
