NO3:PO4
 

Any one out their use red see nopox?
I used it to a year no problems. Then weaned my self off it. After a couple mouths I couldn't maintain low no3. So I started back on it. As expected. It's doing a good job. But I'm am getting cyanobacteria again. I noticed while off it was all gone. Now tank gets just covered again.
Is this the imbalance in nutreances?

Salinity 1.25
Temp 77
Alk 8.4
Cal 430
Mag 1340
No3 2
Po4 0.03

Is this normal? I had it last to.e also.
Any tips? Or exsperance?

Ultimately would love to be off it. But tank seems to run too rich in no3

That level of offset from NO3 and Po4 shouldn't cause your cyano. You have other contributing factors. got a pic of the tank and how it's set up?

Last week no3 was over 50.https://uploads.tapatalk-cdn.com/201...11f8c6ddec.jpghttps://uploads.tapatalk-cdn.com/201...39957809d0.jpg

Could be the change in nitrates (being reduced quickly). My tank is about to it 2 months after the transfer, I used all new sand and added some cured LR. I’m currently dealing with cyano myself, it’s on the sandbed and on the rocks trying to cover corals :angry:

As far as NOPOx goes, I used it in my overstocked 150g and it was a beast in nitrate reduction. The only negative was bacteria clumps in my sump (looked like a yellow/brown slime). I would use a turkey baster and suck it out.

I have used nopox to get rid of cyno, it worked well for me.
Could be your flow isn't strong enough in those areas, cyno likes low flow areas.

Yah, if I were to venture a guess, I'd first tackle the flow. Looks like you have a pair of Apex pumps in there, which would normally be sufficient, but your rockwork is really dense. A couple smaller pumps (Sicce Xtreams, etc) behind the rock would do wonders. That or you could just open up the rockwork.

Also, how is your sump set up? Are there any large piles of detritus?

Nice Candy Basslet btw!

If you use biopellets and plumb the reactor outlet to the skimmer inlet you will get much less cyano problem. Dosing products into the water column (liquid carbon dosing) I see a lot more cyano.

Nice suggestion. I'll try somthing behind rock.
Sump is good. I'll get some build up on the rock but carbon ushualy cleans it up.
I get a build up of carbon and gfo from the reactors which I don't like.
In the sump I've got 30lbs live rock 2 LF reactors a baby pawerhead 6 mangroves a reef octopus and filter sock which I change daily.

I like that idea. But have never used them.
