    What is the best phosphate remover?

    I’ve been struggling with keeping my phosphates under 1ppm and was wondering if I should try harder with doing water changes more frequently as in twice a week? Or should go to get a phosphate remover? Both my tanks have HOB equipment if that makes a difference with anything. I will post my...

    EMERGENCY Phosphates at 10?!

    Hi, i just tested my water with API reef kit yesterday and my phosphates read 10 (not 1.0, I am not mistaken). I've been running some chemipure blue and it looks like that wasn't enough so I added some chemipure elite and the algae growth has slowed down a bit since adding yesterday. Is this the...

    NO3 & PO4 . . . Why can't I get this right?

    OK, so I've been battling high NO3 & PO4 for a couple of weeks now. I've read almost every thread with the same issues, but I can't seem to get any subtle changes for the better. I'm at a loss for what to do. I'm not looking for a quick fix, but I'd love to be able to see *some* changes for the...

    My Plan to Reduce PO4 & NO3

    So, we've been trying to reduce PO4 slowly (started the whole process with 0.8) to get more coloration out of our SPS. We actually have a lot of great growth and no algae in our system, which we've been very happy about. We are currently running ROWAphos and Triton Carbon (2 cups each) in our...

    Aquaforest vs Salifert phosphate tests

    Hi everyone, I'm sure this has been answered numerous times but I can't find a comparison thread with these 2 specific tests. Hanna is out of my price range before you ask ;) I see that a lot of people get zero readings on their Salifert kits, hopefully that means their actual levels are close...

    Hanna Phosphate ULR

    Hey everyone. I just received my Hanna checker and honestly, I’ve confused myself on what phosphate level i should be shooting for. I keep reading that I need to be around .02. Today I tested with a .28 and started panicking. But I have no algae problems and my corals looks fine. If this level...

    Kalkwasser bottoming out phosphate?

    Hi a few days ago I started dripping fully saturated kalkwasser into my 50 gallon and my phosphates have been at 0 since. Im currently dripping around 3ml/min. Before I started dosing I was consistently at .03 ppm using only a large skimmer. Is it possible for the kalk to drop my phosphates so...

    Phosphate and Nitrate out of balance. Help needed, stupid reefer here.

    Yeah the title sums it up. Phosphate was 0.7 so I used GFO and nopox to get it down to zero. Got dino, let the tank dirty out for months fed food, skimmer offline. Dino went away and now I have 25 nitrate and zero phosphate. Luckily I only have a couple of softies in the tank so nothing too...

    P04 Issues

    Alright, where to to begin. I have had a 80 gallon with a 30 gallon sump tank running for almost a year and a half after a restart. I got dry rock and dry sand, which is a mistake on my part, and I am on a fun roller coaster right now. Around 5 months into my restart things were going okay...

    Nitrate Levels in Aquaria vs Wild Reef Nutrition

    I often wonder how wild reefs are able to grow and thrive with such low levels of dissolved nutrients - namely nitrates and phosphates. I have an SPS/Acropora dominant tank and I maintain KNO3 solution on a dosing pump just to keep the corals alive - I try to maintain nitrates up to 5ppm...

    How necessary is it to clean your skimmer neck/cup.

    So - a recent thread reminded me of a question - how often do people clean their skimmer neck/cup. I do not do it regularly - and it tends to have a thick coating of 'gunk'. I always wondered if that was putting bad stuff 'back' into the tank - though I dont think it does. Answer the poll -...

    Good Nitrate to Phosphate ratio for a reef tank?

    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...

    How Many Test Kits Do You Have?

    I know...I have a problem. I was organizing my supply cabinet and realized I have clearly accumulated more test kits than should ever be necessary. BUT it has been helpful having everything I need at arms reach, and the ease of use of these kits has caused me to test consistently, which I’m...

    Phosphate testing

    I have a 180 gal mixed reef about a year old. I’ve been using GFO kind of blindly off and on for the last several months, I don’t use the GFO unless progress seems to slow down and it has always seemed to help my corals grow better again but I’ve read several horror stories about overuse of GFO...

    Phosphate Control

    My phosphate level (with Hanna UL checker is running in the 0.1 level. I would like to drop it to below this as recommended. I have been feeding less in general (mysis in the PM and pellets in the AM) and have about 8 fish, none bigger than about 2 inches in a 100 gallon with about 20 gal...
