    How to set up a RDSB?

    in General Discussion

    Andy, this may be at the heart of your problem. By taking out a 100# of rock two weeks ago, you've decreased your biofiltration by nearly 50%. Your remaining rock may be able to catch up, but you've got a lot of fish that makes up for a large bioload. It may or may not catch up. GFO can help reduce phosphate, but it will do nothing for nitrate. It may, in fact, limit the uptake of nitrate if you're too phosphate limited. (I doubt that's the case, though, because you must be feeding heavily to sustain this many fish).

     

    Do you have any room to put that 100# of rock back in? Maybe a sump?

     

    Watch your nitrate levels. If they continue to creep up at the same rate, without backing off, you're either going to have to increase your filtration or decrease your bioload. Water changes to manage nitrate, by the way, will lead to quicker depletion of alkalinity relative to calcium. The end effect is that you'll have to dose alkalinity to maintain balance.

     

    You might be able to use a denitrator coil or sulfur denitrator, but I don't know how much coil would be required to replace 100# of rock. I've never seen a guideline for this.

     

    Carbon dosing can increase the bacteria in your system. Effectively, what you're doing is you're providing more low-nitrogen food for them. This can increase numbers, raising the uptake of carbon, nitrates, and phosphates. If you don't have enough anaerobic surface, though, for bacteria to colonize, this could become the limiting factor.

    I sold the rocks also no room in the sump.

    I think you are highly overstocked (I tend to be conservative, so others may disagree). How long has your tank been up for? 100 pounds of rock and a minimal sandbed are not going to cut it for a bioload that big. Are you running the GFO reactor?

    The tank been up for 10 months.

    Yes I am using the BRS dual reactor for carbon and GFO.

     

    Tom, what is carbon dosing and how it works?

    I have about 100 pounds LR there, it was 200 pounds or so LR in there but I like the open look. I took 100 pounds LR out 2 weeks ago but it been high nitrate.

    I feed them once a day+seaweed every other day. I have 25 fish there, 6 tangs and an angel from 4" to 6" the rest of them are small.

     

    And I have a BRS dual reactor for carbon and GFO.

     

    I been feeding frozen food w/o rinse it with rodi water might be one thing.

     

    Does the sulfur denitrator really works?

    anh Andy, my is set up with 2-30 gallon tanks. Both are about 6in deep, fine sand, slow flow. it's part of the system. Main tank drain into the first 30 gallon, then skimmer tank, and finally the second 30 gallon tank, which is where the return is as well. not sure if this answer your question tho :blush:

     

    let me know if you need help setting one up at your place.

    The wife don't want me to set up more tank :sad: So i just want to use a bucket. Thinking to Drill 2 small hole to the bucket near the top and one for drain the other for return(maybe a maxi-jet).

    Last month i had a high nitrate problem, I lost 50% of my SPS. But it been under controled by alot of water change. From 90 ppm to now 10 ppm. Anyway I am learning toward to a RDSB. How do you set up a RDSB in a 5g bucket? It is basiclly put alot of sand to a bucket and water in and out from the bucket. If you have pictures to show that be great. Thanks in advance.

     

    BTW my sump have a small section for refugium and alot of sand in there with cheato so not much room for the cheato. So i want to remove the sand to a RDSB.
