algae control

I'm torn between having a clean up crew or not to have a cleanup crew in my mixed reef tank that is about 2 years old now (80 gallon fijicube). I probably work on my tank too much and have gyres with a good amount of water movement, but spend a lot of time blowing algae off the rocks and...

I have had an emerald crab in my tank for almost 3 months now. He is generally a good tank mate, and has good personality. He does great on the algae on my rocks, and even solved a Bryopsis outbreak I had. The problem…he is molting about one a month, and is approximately 2-3 times larger than...

Hey guys any help in identifying what kinda algae this is would be great. Also is it harmful or just unsightly? Any recommendations how to get it to go away?

Hi! I'm looking for recommendations for captive bread algae eating saltwater fish (and ideally also recommendations of where to find them in Europe). From what I've seen it is possible to find captive bred: - Yellow Tangs - Angelfish - Rainford's Goby (although I've seen debate about whether...

Hi, Need help ID'ing this nuisance algae in my tank. It starts as a small round bump, then appears to start growing a stalk/stem. It is a light green/yellow color and can apparently grow with next to no light as its inside of caves in my rockwork. Please help! I'm thinking maybe bubble algae...

Hi, My bleeding apple scoly have some black slime, probably some weird algea covering the back of the coral and slowly taking over the tissue of the coral. It's kinda weird since I don't have any algea problem in the tank and the reverse apple just beside it is doing fine. And no fish or invert...

So I got a 25-gallon tank with a complete setup for freshwater fish, but I want to build a reef instead. I'm looking for the most affordable options for sumps, return pumps, power heads, and what all is absolutely essential to maintain a reef. I know that sumps aren't essential, but do I still...

I've been fighting bubble algae on and off for about a year now and I'm getting tired of it. I physically remove them with a hose and screw driver and they come back within a week. They detach from rock and end up in my powerheads, causing cascading issues. I'd rather grow GSP because at least...

The two go together like PB+J. My current build uses quite a bit of soft silicone tube, and I get a lot of growth in these lines, and meaning that adjustments to the overflow and return are common. While keeping them out of light is the obvious option, and has worked quite well for some of my...

Yet another person in need of an Algae ID. I have reviewed things online, and I'm just not skilled in the art of ID apparently. I do have a microscope, but I'm not sure what areas need to be photographed that would help. So, here are some in-tank, on a white paper plate and then under a...

Hi , Had an outbreak of Cyano / Dyano and it killed a few of my corals.Being a new reefer it was difficult for me but finally figured out. I am sharing this just in case its helpful for another new bee. 250G system (Display tank 1 - 150G, Display tank 2 - 50G - Sump - 36 and refugium - 29G)...

I recently started up my tank about 6 weeks ago and have now gotten this algae outbreak out of no where. It’s brown algae across the rocks and also across the sand which has been a nuisance since it’s constantly seems to come back. I also seem to see a weird haze in my tank but only really...

Hi all! I'm not exactly new to reefing but I'm new to the forum (been lurking for awhile. I only created the account to ask this question). For months I've been sort of battling algae on my tank walls (mixed reef; top half SPS bottom half LPS and softies). It's this greenish film that comes off...

I have a 45g cube tank and just ordered a Coralife Turbo Twist 6x, but after reading, I'm wondering if I should have gotten a higher wattage. It's 18w and said up to 250g, but I imagine that is not for saltwater. Primary objective is to use it for reducing cyano and dinos, currently having a...

Anyone know what I should do in order to get rid of this algae? i had dino’s at first, did a 3 day blackout and now they’re gone but I have a different algae growing. Any idea of what I should do?

What type of algae is this and what should I do about it

This bacteria or algae is taking over my tank and making my leather corals shrink. Please help me fix this? Phosphate are zero, ammonia is zero, nitrite is zero, nitrate is zero, alkalinity, calcium, and magnesium all in range. Don’t know what else to do. I have done water changes, changed...

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...
