Dosing nutrients helped dino's in my tank but they will always be on Grube's gorgonian, sometimes on certain Zoas forcing them to close. On tips of stag and digitata.In for results. My tank makes nutrients dissapear quickly as well. And if I feed a lot I get nuisance bacteria explosions such as dinos and cyano.
Hi, this is why I added a second tang in my 65 all food gets consumed and corals uptake ammonia directly. When you have a densely packed tank of coral you would be surprised how much ammonia and phosphate is taken and how little is left.You really think fish poop will do the trick? I added a purple tang in april. A skimmer in july.
Hi are you using a skimmer? The one I'm using is rated for 66 gallons. I've got about 60 gallons total volume.Hi, this is why I added a second tang in my 65 all food gets consumed and corals uptake ammonia directly.

Indeed, I use a Red Sea rsk 300 which is rated for 80g heavy load.I do realise skimmers can strip a tank clean but the benefits just outweigh the bad. I have had my skimmers air line fed directly by outside air and it was the most Noticeable benefit I have made.Hi are you using a skimmer? The one I'm using is rated for 66 gallons.

The Tunze 9004 is rated 20 gallon heavy bioload. This tank was skimmerless for 3 months with the purple tang. Had hair algae popping up everywhere and cyano. Skimmer has helped a lot.Indeed, I use a Red Sea rsk 300 which is rated for 80g heavy load....
My impression from the R2R posts is that elevating PO4 and NO3 to detectable levels is beneficial to coral. I also assume that means constantly elevated.Indeed. I feed 9 fishes at least twice a day. There's detritus all over the floor. The only time I can test detectable the next day is if I dose atleast .05 phosphates and 4 ppm nitrates. But the corals don't respond well. Zoas seem fine as well as goniopora. Feeding more hasn't gotten great responses either. Cyano patches on frag rack and high up on rock show up.
I believe some denitrifying bacteria is really effective in this tank. But where? Inside the reef saver rock? It's extremely dense.
Could the biomass of these corals really uptake that much nutrients that I can't even detect them? Then why aren't they thriving and reaching their potential?
Oh that's really interesting... I need to do some digging.This last point brings up another idea. There may not be too many denitrifying bacteria but too many heterotrophic bacteria stripping the system of nutrients before they can become nitrates.
The quick removal of nitrate you observe can also occur when dosing carbon or by an abundance of algae. If you turned out the light for one day would nitrate consumption stop? (I don’t recommend this unless it does not harm the coral).
Hi I've had another reef tank in this house before that had no issues. Then I upgraded and used Seed to cycle.
Hi I ran this tank without a skimmer for 3 months with weekly water 6 gallon water changes. By the end of the week there would be cyano patches. Hair algae all over the powerfilter. I clean the glass everyday. I ended up doing two water changes a week until my skimmer arrived.This has nothing to do with your cycle or denitrifying bacteria. It maybe that your import is lower than your export - IF your tests are correct. what are you using to test your nitrates and phosphates ?
You mention that you had hair algae problems without the skimmer suggesting that you had excess nutrients at that time. But you also say you have zero nutrients for 2 years. Something doesnt add up.
Fix the import side like someone else said you need more fish and feed more, or lower the export by taking skimmer offline (fully or partially) and soon you will be complaining of too much nutrients again.
