nutrients

Hi guys I have been struggling with what I think is cyano for over a year now. A little bit of cyano doesn't bother me but lately it has started to cover my whole sandbed and creep onto the rocks. I am unsure whether I am nutrient deficient or have too many nutrients. Nitrates and phosphates are...

Will Xenia rob a tank of nutrients if allowed to grow out large? I read that in another post on another forum but that sounds like crap to me. Dad had a bunch in his 180 that just disappeared one day. Just trying to make sure these dudes won’t rob my tank of all nutrients and kill my Zoa collection.

So my phosphate is reliable between 0.03-0.06, ranging between there month to month. However over the last 4-6 months, my nitrate has been going from 5, to 3, to 1... to now just barely detectable. Why do you think my phosphate can stay so consistent, but my nitrates are diminishing? Any ideas...

I'm a bit overwhelmed by the number of Hanna Checker for phosphate. I've opened a poll to see which one you guys use. Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get? The HI774 sounds like the best choice for someone who...

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...

I have one tank with lots of xenia growing all over that I have to regularly prune and another tank with no xenia. The tank with the xenia consistently has lower nitrates than the one without. It also seems to require much less maintenance. Is the xenia consuming the nutrients in my tank an they...

Hi all! Im just cycling a new tank with complete dry rock. I had no lights on for the first 3 month and threw a shrimp into the tank and added some bacteria. The bacteria broke down the shrimp and i had some nutrients in the tank all the time. After 3 months ive added some fish and switched...

So - everyone here with an SPS related tank is concerned about growth. Without googling:). What is the maximum growth to expect from SPS within a year?

I Currently have a JBJ AIO 30 Gallon tank, I was going to put a sump under it, well the Esshops cube Medium I ordered is 1" to big, so I looked into getting a stand. Then I found a new tank I bought it cheap. 31x31x15! Love it! BUT.... the concern now is I bought a skimz quitepro 2.0 return...

Hello! Over the years this has been one of my favorite subjects. A while back I noticed my tanks doing a lot better with more NO3 than PO4. When the NO3 matched the PO4 on the lower side the tank begin to grow hair algae in the sump, and dark brown algae on the rocks, overflow box, sand-bed...

Okay so I have a 215 gallon reef, trying to get nutrient levels into low, readable ranges. I have increased my bio load, feeding heavily (frozen), I can get my phosphates to increase, but can't get anything to read when I test nitrate. My phosphate got even higher than I wanted, up to .94, back...

I am new to reefing but have kept fish for many years. 75/30g Tank started in Oct 2017 Parameters all 8, .ca 420 Mag 1500 (little higb), salinity 34 2 Clowns 2 reef chromis 1 blenny 1 goby Roughly 30 various lps: hammer frogspawn lepta lepto cypha psamm favia duncan acan micromussa paly All frag...

I think my tank suffered from lack of nitrates. I was dealing with some GHA and always testing zero for NO3 and PO4. I think my nitrates were actually too low, but the phosphates were used by the GHA. A few weeks back I dosed a few capfuls of Seachem flourish nitrogen over a few days, but then I...

Since my display is just three live rock pillars, I currently have a live rock section in my sump that is full or rock rubble. The live rock section measures 10"W x 20" L x 7" D. Right now it just has live rock rubble and a backup thermometer. Not sure how much biological filtration it...

I have a 45 gallon cube that I started back in February. Things have been going very well except a couple of small things I'm troubleshooting with one or two coral frags. Recent Test Results: Nitrate: 1.5ppm Ammonia & Nitrite: 0ppm Calcium: 430ppm Alk: 8.4dkh Magnesium: 1500 PH: 8.1 Phosphate...

I finally got curious enough to try out the Triton testing out and thought Id post my results here and see what you all think. First some background info. My system is about 300 gallons total and is made up of 3 tanks plus a sump. I have a mixed selection of coral and a not so heavy fishload...

Is it sufficient to feed ULNS (w/ SPS, LPS, Morphs) with Reef Roids only? #reefsquad #LPSexperts #SPSexperts And being known to be lazy, is it acceptable to just broadcast the food with the wavemakers, return and skimmer on? #lazy

For those folks that maintain ULNS, I'm assuming you need to feed your tank heavily in order not to starve your corals? be that softies, LPS or SPS. What do you feed your corals and When do you feed your corals? The likes of LPS/SPS as we know, when the lighting is off, their tentacles are...

I'm still beginning my first reef tank and know very little about some of the basic additives I'll need for a successful tank. I don't have much money to spend so I'd like to know some of the most influential or basic additives I could get and have on hand. Could anyone please shed some light on...

I have recently had the emergence of brown algae on my sandbed that has coincided with some other inconsistencies in my 180. All within the past month, I have had: Emergence of Diatoms, mostly on sandbed. darker in some areas, non existent where there is no light (under rock/coral overhangs...

My 110 has been running for about 6 months now. I started strong with low nutrients and very little algae growth, but with the addition of some sps, I stopped vodka dosing so the nutrients would go up. So at this point I have a tank that has enough corals in it that aren't doing well (I've...
