gha

I have had my tank for a little over a year now and everything was great until about 2-3 months ago. I had a bad outbreak of GHA and got it under control but them it came back with a vengeance. I stepped up my game and reduced lighting, reduced feeding, increased water changes, aggressively...

Hey all, I have been struggling with nutrient export as of late (along with an outbreak of GHA) and have been working to reduce nitrates and phosphate through all of the traditional routes (water changes, reduction of feeding amount/time, consistent cleaning of filter and protein skimmer, etc.)...

45 AIO is currently beyond overrun with GHA and dinos. Any and all help would be appreciated, because this is about to drive me out of the hobby entirely. I haven't bothered testing nitrate and phosphate because they're likely zero'd out given the sheer amount of algae in the DT. FWIW, is an...

Can’t seem to find an answer. Getting ready to dose Flux RX in my 120 with sump. I bought the pack that treats up to 350 gallons. However, the instructions only start with dosing a 225 and goes up. How much should I dose for a 120? Half the does required by the instructions for a 250? Also, just...

I began my reef hobby nearly 6 months ago with a 13.5 Fluval EVO, and I've had great luck with it thus far (knocking on all the wood available). So far the only major problem I have encountered was a salinity spike that nearly killed my hammer (Beginner mistake- I relied on a cheap hydrometer)...

I do daily automatic water changes (1.5 gallons) on my 90 gallon with 20 gallon sump, I have a bad GHA outbreak and bought vibrant, my question is will the daily water changes make the vibrant less effective or not effective at all? Has anyone used vibrant while doing daily water changes with...

I'm currently battling a GHA problem on my 45 AIO cube and am just completely at a loss. Willing to hear any and all advice and would prefer not to use Vibrant since I've read horror stories. I used Reef Flux to fix this in the past but would prefer not to run it again and just figure out where...

I should start by saying, I do not have all the answers, in fact, I hardly have any. After combing the forums daily for weeks, I realized that there are hundreds(thousands?) of threads concerning GHA. Unfortunately many of these threads have either gone unanswered, or the answers varied greatly...

Can someone please help me identify this nuisance alage I am having for the last 2 months now. I have an established 5year old SPS dominant system. My Nitrate is between 0-5ppm and my PO4 is 0.04 checked with Hanna URL checker. All the inhabitants of the tank are doing good. VIDEO:

A few months ago my lfs convinced me to buy some live rock to speed up my cycle. It was a huge mistake. First, I got GHA. Next, I saw an aiptasia coming out of the rock. They sold me some F-Aptasia to get rid of it. It worked. The next day I saw multiple aphasia coming out of the rock along...

Hi all, Wanted to bounce some ideas off of you. I have developed a pretty bad patch of GHA in a pretty small area around the bases of some of my SPS. It’s right at the highest PAR area of the tank, which I’m sure isn’t helping. I have 30-40 astrea sp. and turbo snails, a green pistol shrimp...

Hello! I am facing some type of algae that I’m having a hard time eradicating and properly identifying. But first some tank back ground. My tank is a Red Sea reefer 425xl. It has been running for 148 days. Up until last week my nitrates and phosphates had bottomed out to 0. As such I have...

Hello, I am currently battling prorocentrum dinos and am making solid progress. I have a forest of GHA now, but it is now becoming problematic. It is housing stray dinos in it, while also suffocating my Xenia. Even though it is a competitor for the dinos, it is also a major nuisance. I want to...

Good evening, This is my first post to this forum so here's to hoping everything goes well! haha I've been wondering why my tank hasn't been doing too good for the past 2-3 months. The corals have basically been retracted and slowly dying off for the previous time stated. my current tank...

I posted a few days ago and didn’t get any helpful responses. Can someone please help me identify this algae? I scrubbed my tank and did a water change Friday evening and now it has all just come back so quickly. Is this GHA or bryopsis? Or is it something else by chance? I want to...

Hello. I need help to get rid of GHA. It's all over my back side of a tank (600 l). Tank is 3 years old and before this, I didn't have any algae issue. All the parameters are stabile for a long time. I have a mix tank, with a lot of SPS. I dose complete Red Sea program, and the only thing that I...

I’ve been battling GHA for a few months now and It’s upsetting because I got it on a frag plug from my LFS. It has only spread a little bit and it pulls off easily so my nitrates are >5ppm and phosphate is around >0.15. I have tried flipping rocks upside down to cover the GHA, manual removal...

I've had my tank running for a few months now. I cycled the tank with microbacters cycling kit, the cycle went great and was done within a couple of weeks. This sort of dust algae appeared about two weeks ago and then some GHA. I added 3 emerald crabs to keep up with the hair algae but now the...

The battle with GHA is turning toward victory. The last coral to be cleaned is a small section of yellow polyps. What’s the best method? Is there a risk of poisoning the tank if I’m too aggressive with it. Sorry if these are rookie questions.

ok so my cheato has been introduced to green hair algae and now it’s growing with my cheato in the back second chamber of my tank my question is besides cleaning off the cheato and loosing pods that and doing harvesting one the gha as well as the cheato is there a way that i can introduce a...

Can anybody help me ID this strain of algae? It is brown/red under my lights and appears more green in the sunlight. It is tougher to remove and slips out of my fingers easily during manual removal, anchors to rock very well and grows on SPS that otherwise appear very happy. Thin and hairy...

If you do have or did have GHA, do you prefer a natural way of removing it with a clean up crew and manual removal by hand and suchion. Or do you prefer to use chemicals?

I was working on my bi-weekly water change and this week I cleaned out all my equipment in my tank. Well, when I was looking in the sump, I noticed quite a bit of either GHA or Bryprosis in the sump of my AIO. Any tips on removing or whatnot and how to keep it from spreading? I'm starting to...
