nutrients

These might help in understanding

Let's talk nutrients The words "nutrient" and "nutrition" are commonly confused when talking about reefs. "Nutrition" is just like food; it feeds the fish and the corals and the microbes. Nutrition include fish waste, coral slime, leftover food particles, algae, vitamins, and amino acids. This...

For those that like details... One way to view nutrients is "flow" (like a river) instead of "level". By keeping a very high "flow" of nutrients, by providing both a heavy input of nutrition and a heavy export of nutrients, it's like a fast flowing but shallow river. This type of flow is how...

Hey guys. I am really struggling. I cannot figure out how in the world to get my phosphates up from 0. My corals are starving to death. I have 5 fish in my 100 gallon. It’s more than a year old. Barely any corals except some GSP. Everything else starved and is dead. Honestly I’m not sure if...

What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in...

Hello my tank is about 1.5 yrs old, im having a green hair algae problem but its only growing on one piece of my rockscape, im aware there are fish and inverts that will help remove it and general maintenance will help as well but im looking for help on understanding why this is occurring? Its a...

These are the results from today, same as it was the last time I tested 1.5 years ago. Is there really a benefit to testing these parameters weekly or monthly if I keep getting the same results every time?

Hello and happy weekend. I've had a reef tank, or have been trying to successfully get one up and running for a year now. It has been in operation in that time but it had a little good and an extended bad period. I'll give a history but then I'd like to get to solving the current problem because...

Hello Everybody, I am new to the Saltwater world and I thoroughly enjoy reading all of the forums and hearing the input and advice. One thing I have been trying to do research in now that I have started getting corals up and running is maintaining nutrients. Do you guys recommend consistent...

I’m an intermediate reefer and I have my main display which is a 100 gallon tank sps dominant mixed reef and that tank blooms with healthy corals and full of fish and I have been successful in controlling nutrients and chemistry. Anyways I have a 13.5 gallon tank (fluval evo) I’ve been running...

Hello friends, My 125 has had coral in it for almost a year at this point (coral is light-moderately stocked, 40ish pieces). I have had great success learning on here from other reefers and got my tank dialed in nicely. The one area I haven't been able to get consistent is nutrients...

Going to be setting up a 24 x 24 frag tank. (no SPS) I have a couple questions 1) is it sustainable to have this tank operate without fish? 2) what’s the best way to get enough nutrients in the system?.. use filtration to strip it and use dosing, or would feeding the corals be enough? (setting...

I have homed in my vinegar dosing to 60ml a day. This deals with 6 cubes a day plus some mysis rs flake and spectrum pellets. I tend to feed in the evening and wondering whether this is causing very high nutrients and low the rest of the time. I was spreading it out to 24 times a day through a...

NP-Bacto-Balance essentially supplies nutrients to the corals at the lowest levels right? So, would these levels show in a test kit? Can you explain the process of dialing in my dosage for this product? I'm starting at 0.40 mL for my (40 gallon DT, 20 gallon sump) tank.

I'm currently running a 32 Biocube. Here is livestock: 1 Clownfish (going to be getting a female soon) 1 Snowflake Eel Parameters: Nitrates 34.6 PPM PH 8.1 Phosphate: 0.49 PPM I'm trying to get phosphates down to 0.003 at least. I've added a refugium recently so I think that'll help. I've had...

Hi guys, Just wondering if anyone happens to know what nutrient (PO4 and NO3) levels Than @Tidal Gardens runs in his coral propagation facility. I vaguely remember his phosphate is between 0.1-0.2. And if anyone knows what model of Radion he is using? Blues or Pros? Schedule and intensity...

Hello! Rather new to the hobby here but my tank has been running for just over 6 months. I’ve had coral for almost 3 months. Went through a few different ugly stages already. I thought things were finally calming down where everything was clean again for almost a month and everyone has been...

Hey, I found recent AF product - Anti Phosphate - https://aquaforest.eu/freshwater/products/af-anti-phosphate/ It's relatively light color, so it does not seem to be a ferric hydroxide related as most of reef dedicated products are. I wonder - what could be the ingredient and why isn't it...

Recently got a new 15 gallon tank and just tested after adding zoas and a gsp frag. Noticed they weren’t doing well compared to my 13.5 tank. These are the results. Need help in trying to figure out a solution. Doing a water change now hoping it’ll help. Tank has a filter sock and filter floss...

I've used AF Life Source 2-3 times now according to the instructions. My corals and snails seem to like it, but my fish get very nervous when the mud clouds the water. Clowns go all the way into the anemone, blenny hides and my six-line has a panick attack (jerky movements like he is gasping for...

Hey guys and girls. Any experience on using/dosing food grade calcium carbonate capsules mixed in ro di to act as a flocculant, bind all the degraded stuff and then dose some bacteria product to remove them from the system. Any opinions? Do you believe it will have any adverse effects?

Please share here your preferred method, when it comes to using GFO (Granular Ferric Oxide) . Do you run 24/7, intermittently or never? Leave some details about your system (age of your reef, size of your tank, type of coral, what reactor you run, what you feed, substrate or none) and reason for...

I haven't really seen the topic of nutrition levels in the new tank discussed before. My situation is I am transferring my 5 month old Fluval Flex 9 gallon with one fish, clean up crew and corals to a Red Sea Reefer 170 that's been running for a week to let the sump stabilize and to get familiar...
