nutrient control

phosphates help growth in coral but also brings algae and lose of coral color. How important is phosphate in saltwater aquarium? I rather have mid nitrates levels 15-20 ppm maybe push 40ppm before 10% water change all while keeping phosphate levels low. Calcium will be readily available and more...

Hi there, I'm looking at Algae Scrubber solutions for an AIO since I had some good success with it in previous tanks. I have a 50 gallon IM Nuvo Lagoon. It looks like this scrubber will fit on the back of my tank pretty well, but I was wondering if someone had any personal experience with...

I have a reefer 250 v1 with a Red Sea reefer 300 protein skimmer that in my opinion sucks .. I was debating on removing it for an algae scrubber then I was wondering about removing it and just throwing a light and some macro algae there instead.it would save me some cash but would it be...

About a year old, in tank for a few months but didn't fit very well in my sump so it was a pain to clean. Everything works, comes with pump Asking 350$

Bacto Reef Balls are the first fully available marine bacteria to feature nutrient control through the use of time release technology; depot controlled nutrient control. High Efficiency Nutrient Control BACTO REEF BALLS contain highly effective bacteria cultures that control nutrient levels...

The third nutrient is my theoretical thinking on nutrients and understanding of aquarium stability and balance. The third nutrient or Carbon is a nutrient that not often talked about and little is known of its function and effects to the other Nutrients in reef aquaria, not much is know to...

Hi y’all, my Biocube has recently been pounced on by some sort of algae or Dinos i think. I wasn’t able to get the best pictures but it’s like brownish color and at first I thought it was just diatoms but now it’s long and grasslike and billows in the current. It’s all over my glass but only a...

Hey all, I have been struggling with nutrient export as of late (along with an outbreak of GHA) and have been working to reduce nitrates and phosphate through all of the traditional routes (water changes, reduction of feeding amount/time, consistent cleaning of filter and protein skimmer, etc.)...

Hi everyone! I need some advice and this is the best place in the world for high quality reef advice, so please bear with me and thanks in advance for your help! Basically I was skimmerless for a couple of weeks after removing my previous skimmer to prepare the sump for a skimmer upgrade and...

Hey All, Im in a bit of a frustrating circle of events that I'm trying to balance and just looking for some advice on how others have balanced this. The tank is about two months old. It's a 120gallon peninsula system. Overall it's doing great, battling some diatoms at the moment but nothing...

Could seagrasses be the solution to deep sand bed issues? My belief is that they could eliminate nutrient and organic buildup as they can only take in nutrients through their roots (edit: when they become too much for the bacteria and other organisms in the sand to handle). As a bonus, they also...

I am having an issue with my tank. I’m struggling with cyano. My tank is a 25 gallon AIO with a Tunze 9001 skimmer, filter floss, and chemi pure blue. My phos is currently 0.11 and my nitrate is 0.0. These parameters have been largely the same regardless of water changes. I’m currently up to a 5...

Hello there, just as a small preface I have been in the hobby for about 5 years and now am coming back from a break. I have an 80 litre nano that is now 2 months old. Nutrients were a problem because they were super low super fast. I did use exclusively live rock and a little bit of live sand to...

My tank has been up and running for about a month. The rock has been fully cycled for almost 3 months. I’m currently in an ugly phase. My phosphate is 0.05 and my nitrates have been between 5 and 10. I have a mix of macro algae and coral. What I’m wondering is, is there anything I need to...

I recently reduced my skimmer run time to 6 hours. I have very low PO4 and NO4, each running frequently at or near zero based on ULR Hanna and Nyos tests respectively. I also run a refugium to help maintain low values but also dose Neonitro and Neophos to keep them up. I was curious how others...

I did an ICP test, and I'm low in all of the elents found in both of these solutions. Any particular thoughts on using them in general? Any thoughts on which is better?

I dosed Vibrant several times with some good results, but algae still grows. I know it will look great over time, but long term will not solve my nutrient issues. I know managing a refugium is going to be a better solution long-term. I did not realize how detrimental it was to Macroalgae and...

Hello! I will summarize at the end and provide photos if you don't want to read my initial tank journey from start to now, but here we go! I included the journey only because maybe there was a misstep I took that can explain things. Look for the colored markers if you want quick notes, and...

This quote summarises my current understanding of nutrient reduction with biopellets: If biopellets reduce N and P in a 16:1 ratio, then it follows that by providing excessive nitrogen (not NO3), phosphate should be reduced further, while nitrate should still be at an undetectable level. Can I...

Hello all, I am looking into upgrading the stock filtration on my Fluval Evo 13.5. I have been running the stock system for around 1.5 years and I am not seeing the kind of results I would like to. I believe there are too many nutrients building up in the stock sponge. Here is the diagram of...

Hi, new to the forum! So. I have a 70 gallon tank, mostly softies. Running 2 viparspectra 165s. 10 inches off the water. 23 inch tall tank. Off the topic i really wanna know the answer to but what should I run the intensities at? Should I alter the stock lights in any way etc etc. The real...

Ok, so I have a 15 gallon with a clownfish, royal gramma, cleaner shrimp and cuc. I was having bryopsis issues, got rid of that but now I have green slime algae and red cyano in full force. Lights run from 10:00 to 9:00. I feed the fish every other day and reef roids once, maybe twice a week. I...

What would be the best way to keep nitrate and phosphate in check with this kind of bioload? (Other than water changes, obviously) My intention is to keep an LPS & Clams 50G tank, including tubastea (yellow and black), and diffent dendrophyllias. I already set up a mini fridge for heavy...
