    Refugium with no skimmer ?

    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...

    The Third Nutrient

    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...

    Help identifying algae

    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...

    Brightwell NO3 and PO4 XPort Cubes

    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.)...

    Balancing Nitrates with Too Much Filtering Or a Smelly Tank

    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...

    A Seagrass and Deep Sand Bed Theory...

    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...

    Cyano getting out of control

    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...

    Dinos and Algae

    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...

    Mixed reef AF formula needs both carbon dosing and GFO?

    I am a bit confused by the mixed-reef-formula. Are NP PRO and PRO BIO S not sufficient to reduce PO4 to lower than 0,04? Does your mixed reef formula also require constant Phosphate Minus use? Instead of using GFO constantly, can I dose Nitraphos Minus, if NO3 is low, but PO4 is high? Thanks

    Flow and nutrient control help

    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...

    Skimmer Time

    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?

    How long after dosing Vibrant can Macroalgae be safe?

    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...

    Biopellets reduce N and P in a 16:1 ratio, can I dose N (not NO3) to reduce PO4 further and achieve a 10:1 ratio?

    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...

    Will This Work? (Fluval Evo 13.5 Filtration Upgrade)

    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...

    Best nutrient reduction strategy for very heavy bioload?

    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...
