    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...

    Kz coral system or red sea trace

    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...

    Yellow/White (stringy/gunk) Coating on Rock and Substrate - 1 Month Old Tank

    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...

    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...

    One algae after another

    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...

    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...

    Need Help With Equipment

    Hello everyone. I have a 75g standard size aquarium that I've had running with fairly little issues. I thought I'd be able to jump into a 20g nano tank pretty easily but it hasn't been as easy of a transition. For reference I have have the Innovative Marine 20g Concept Panorama (pic included of...

    Amino Acids and Non Photosynthetic Coral

    With the growing popularity in the reefing hobby of Amino Acids such as Red Sea’s Reef Energy AB+, I am curious if it makes NPS corals such as Sun Corals and certain Gorgonians, that have been historically considered difficult to keep because of feeding requirements, a bit more accessible to...

    Hey all, I just dosed my last bit of Red Sea (RS) magnesium this morning and calcium plus isn’t far behind. Instead of reordering the Red Sea I’ve had my eye on the Tropic Marin ALL-FOR-REEF BRS has some great reviews and it’s been sold out during covid times. I’m wondering what folks think...

    Nano Build Refugium for Fluval Evo 13.5

    Hi, everyone! I'm looking for information on creating a refugium in the second chamber of my Fluval Evo 13.5. Has anyone done this? If so, did it make a difference in the nutrient levels in your tank? I'm worried that the refugium would be too small to make any noticeable difference. I'd...

    Low nutients in a young system

    I am having a some issues with the LPS corals in my tank that I believe are related to low available nutrients. Most of the coral have lost their "fluffiness" that they had when I bought them. The tank has been running with 0 available nutrient for about a month now. Alk and Ca and salinity...

    Chaeto reactor and light recommendations?

    I have seen a few pre-built options through Marine Depot, but the reactors and lights are out of stock with no guarantee they will return. I have seen some close substitutes, but I’m not really sure what would work best for my tank. I’m not really obsessed with adding more water volume, but I...

    Florida Red Mangrove propagules

    I have some red mangrove seed pods or propagules for sale, harvested off private property. These are actually better at nutrient export than some people assume IME. Some have already started to sprout roots in the bucket. Pricing is 5$ each or 3 for 12, if you are looking for a large quantity...

    Hello fellows reefers I will be setting up my chaeto reactor on my 40 gallon this Friday. The reason is I am trying to lower phosphates without using chemicals. I do not overfeed and do a regular water change once a week and even after changing out around 70% moving home I still have some...

    Please Lord not again

    Afternoon reefers... I upgraded my Fluval Evo to a 60 gallon long AIO back in August when we moved to a new house. I battled nutrients and algae (every kind) over the year that the Evo was running, mostly due to the fact I was new to reefing and made ALL of the rookie mistakes, some over and...
