Marinepure bio blocks

[SFish]

SFish, any calcium based rocks with micro pores will denitrify nitrate provided that there are enough colony to do the job. As long as the condition permits, it will do the job satisfactorily.

Like I said no more then what rocks will do in your sump

I have an 8x8x4 block that I have been cycling for a couple months in a 5 gallon bucket. Nitrates went up to about 20 after adding a shrimp. Now the nitrate level is undetectable. It must do something...

 

[SFish]

Yes it's the same is very efficient live rock.

Low flow and low lite is easy fixed by putting it in a perforated tupperware. Doesn't really help the low O2 levels though.

You need aerobic zone to consume the oxygen before the water goes into the anaerobic area where denitrifying bacteria will use nitrate for cell building and releases nitrogen as by product. Mine does the job quite well, from 40ppm no3 to almost zero in 8 days as shown in the pictures. Up to your imagination how to do it, what media to use. If you have space, that will be a bonus.

R those API test kits? What do have in the tubes of your denitrifier? I assume those are some kinda home made reactors.

 

[SFish]

Can't say if this is true or not but people should be aware of it blocks may contain aluminum which may effect some corals.

Should I add them now to my system while its cycling or after. Does it really matter?

Yup, home made poor man reactor it is.

I see it's a mix of stuff plus carbon dosing. I prefer more natural methods my self. Such as an ATS, DSB, fuge, ect. If your testing with API I would not trust those number by the way.

 

[djbon]

Mixed of stuff that are easily available, mostly free here in my place. Works perfectly after 6 months.

There are a lot of ways to handle NO3 and PO4.

 

[djbon]

Yes, there are many ways to fight no3. Fighting po4 is my next priority. Having no3-po4 imbalance now

You do know that someone recently did a test kit shootout(forget the members name, sorry), and believe it or not, API was actually quite accurate. Its the whole color matching that is tough.

It's also just the ammonia kit that sometimes gives false positives. In my opinion, the difference between 0 and .25 of ammonia is so close in color, most people get confused.

That's why I would not base anything off API test results. For a test with something homemade like what he has I would want an instrument check to see what it's really doing. Nothing wrong with DIY.

I have nyos reefer nitrate test kit as well. I dont want to waste it as i only wanted the API no3 to tell me its close to zero, which is yellow

Here are the same test on 29/8 which is around 40ppm, might be lower.

 

[djbon]

Just for fun, i tested my dt water just now using nyos, and here is the result.

 

[SFish]

Looks like it's working good
