I've been a long time reefer and have had several tanks, but I can't get my wife's 29 Biocubes nitrates to lower?
Mixed reef.
Set up for 4 months.
Live black sand.
About 40lbs of dead rock.
Used Dr. Tim's One and Only plus his ammonia.
2 small clown fish.
2 small wrasses.
The new 9001 TUNZE skimmer
Very little use of activated carbon so far
Reef Crystals salt.
Kalkwasser.
Ammonia- 0
Nitrite-0
PH-7.8-8.0
But, the nitrates are over 40-50 ppm !
Two weeks ago, I did three consecutive days of 7 gallon water changes, but did little of lowering them.
Tested with a new test. Kit, same results..
This tank puzzle's me ?
I do not,.....over feed so that's not the issue.
Might try some GFO.
Hey Kev;
I happen to have a biocube 29 I started in July. I see you mention above adding the tunze 9001 skimmer. What else are you doing in the back? Chemi pure?, Purigen? Refugium? Hopefully, you have already replaced the factory installed bioball trickle filter, as this can lead to a nitrate problem. I am running a media basket with what I mentioned above and a refugium basket growing chaeto.
Rich.
