Below is my chart of my parameters I have been documenting for the past month. I am struggling with nitrate levels. I am feeding twice a day with Brine/Mysis shrimp and doing lower percentage water changes. Also I believe I am having a Cyano outbreak right now? See video below. Should I be...

I have come to the conclusion that I think my two year battle with what is either gha or turf algae is because of leaching phosphates from the rocks. When I started the tank I used brand new macro rock and I have heard that it can leach phosphates that lead to algae. I have no algae anywhere but...

Hi all, I'm currently struggling with some parameter issues. I've attached at the bottom what my levels are as of this past Saturday and a video of my tank. Right now I'm slowly trying to raise my salinity by topping off with 1.026. My pH has be stable at 8 for about two months. My nitrate...

Set up my first reef tank in November and added my first corals a couple of weeks ago and everything is doing amazing! Everything opened up within hours if not minutes and even a blasto which came in pretty rough shape is now thriving. But when I went to test phosphates and nitrates they were...

Hi everyone. I have a 30-gallon tank, with 6 fish, a few RFAs, and soft corals. My phosphates spiked this week, going from about 0.05 to 0.9 ppm on the Hanna checker! (They may have been higher, but that's as high as the checker goes.) A large water changed and some of the Brightwell...

Hi all, I have a 40 gallon live rock only tank, have had it for about 4 months. I have 2 clowns, a midas blenny, and a fire shrimp. They all seem to be thriving, active and eating like champs. I’m hoping to add my first corals, I’m just a little concerned about my phosphate levels. My current...

Hi All, In short, I need to reduce my phosphates. I will being doing water changes now that I've fixed my RODI issue, but I am wondering what the best one time punch phosphate sponge is to speed up this process. Back story for those interested: Had a reefing blunder this past month that I am...

Hi All, Looking for some advice on this issue if possible, Over the past 2 months my Nitrates have gone up as high as 90. I have tried a few things to counter this, Water changes, New filter floss media and Nopox. I have managed to get them down to 77 on the last test. Which as much as my...

Hi all, I have this brown stringy algae growing on my rocks and my sand. I’m having trouble determining if it’s just a brown stringy algae or dinos. As you can see it’s growing in and between corals, likely irritating them. I tested nutrients yesterday and Nitrates are 9 and phosphates are...

Hi , My tank is around 16 month old . I, for the life of me, cannot seem to reduce my phosphate I test bi-monthly with Hanna testers and the result is always 0.9 which I believe is the tester maxing out. All fish are okay however my corals seem to be struggling. I’ve had a full zoa garden seem...

New 7ft long 650 litre mixed reef running for a couple of months although I did use a mix of live rock from my old established system and new dry rock. Things are going pretty well but currently going through the uglies with hair algea and cyano. But both of these are reducing. My issue is I...

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.

Hey all, it's been a few years since I kept a saltwater tank - my expertise is definitely in freshwater and turtles. In the past I had 2 thriving reef tanks with fish & LPS but once my ex and I broke up I kept the freshwater and he took the salt tanks (he was definitely the salt expert!) So...

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...

Hey all, So over the last few weeks I have found tufts if gha in my display. They don't seem to be growing but they are there and driving my crazy. So I decided to break out all my checker and run some test. Well I found I have zero nitrate (hanna hr) and .03 phosphate (hanna ulr). I am...

I'm worried the phosphate has gone up so suddenly. Is this a bad reading? I'm considering buying a GFO & Carbon media reactor. I already have an octo bio pellett reactor and chaeto Growing. I am feeding too much? Could using Bio enhance and coral essentials coral nutrition a and b cause high...

Hi, I’ve noticed that most of my euphyllia have receded flesh from the bottom (hammers, torches), but they opened fine during the day (maybe slightly retracted but unnoticeable). The only issue I’m seeing is 0 phosphate. I’ve tested twice, Last Friday and today with Hanna phosphate URL. Here’s...
