algae control

I have been experiencing a massive phytoplankton bloom over the past few weeks after doing a big clean of my rocks This has gotten so bad to the point of reducing my tanks visibility to < 3" and is starting to take a toll on my mainly photosynthetic corals I have tried big water changes but...

This looks like green hair algae, but would like confirmation before I start treating the wrong thing. Also, based on the images and info below, what you would recommend I do to fix this? I have a 13.5 gallon tank (Fluval Evo) that's been running for about 3 months. I started with dry rock...

Hey reef team, I've got a 25 gallon innovative marine AIO tank. I've been dealing with a bit of hair algae growing on my macro algae, as well as a ton of bubble algae growing on the rocks and frag plugs. I just tested my parameters and currently Alk is 7.5dkh, Ca is 750, Phosphates are 0.0 and...

I fought the good fight with GHA and won. I also discovered I was bottomed out with Nitrate and Phosphate. I'm dosing Phosphate and Nitrate now so I can hold .05ppm Phosphate and 3ppm Nitrate. It was amazing to see my coral perk right up. Anyway that's another thread for another day. Now I have...

I started stocking my tank with some beginner corals. I have some GHA but nothing my CUC, fuge, and tang cant take care of. Everything has gone somewhat smoothly other than my mistakes(water on floor in various rooms smh). I recently got a frag of GSP which was doing well for fist couple weeks...

Shipping available at cost - shipping won't be too bad but INSURANCE WILL BE REQUIRED. Send me your zip and I will send you a shipping estimate. I have a CW-50 from Clear Water Scrubbers for sale. This is Version 1 from CW and would be great for a smaller tank or frag system. These are...

I have been battling GHA off and on now for a good year. It is fluffy green or brown and thick growing in every crevis. My snails, urchins, hermits and crabs don't touch it. The aiptasia battle is a little younger. Both are at a tipping point. When the GHA started to appear I added a GFO reactor...

Hello fellow reefers, my tank has been up and running for about a year & a half and I have been battling Algae and 0.0 readings for Nitrate & Phosphate. I do weekly water changes of 10g, I have a 55g breeder. In my tank I have 2 clownfish, 2 blue chromas, six-line wrasse, coral beauty, pink...

Pax Bellum and 24. Its seen less than a year of use on a tank with a light bioload. Only issues with it are as aesthetic. There are some notable scratches on the top of the heat sink and some small scuffs here and there on the body. Otherwise perfectly functioning and well cleaned. I have the...

New, never used. I've confirmed that all parts are present. Also included is the recommended Rio 2100 pump and two 27.5" support rails in black (one has a chip at the corner, should not affect function, visible in pic). https://www.turbosaquatics.com/features/ Support rails info...

So I'm dealing with dinos. What are these and how to I rid them? Also there's got to be a pod of some sort and some thin things. Help to id these please.

Hi All, I currently have a 6 month old tank that is going through an algae outbreak. I know this is to be expected in a newer tank, but need advice on what I should be doing to mitigate. I know 0 nitrates and 0 phosphates is not good, but I don't know if feeding the tank more will make the algae...

My tank is being overrun by some brown crud and I am uncertain if it is dinos or cyano of some type. I saw quite a few people posting microscope pictures so I obtaned one and tried capturing a few pictures with it. However while I see lots of cool stuff and many little critters moving around I...

My tank is starting to get over run by algae, I know there’s a lot of chemicals and additives to rid algae growth but what is a very quick for sure way to rid algae from corals Skelton, between polyps??? I’m dealing with very annoying hair algae no matter what I do I’m thinking turning off...

Went away for a week and came home to this completely taking over my sump. Protein skimmer working very hard. Used up half my reef mat in 3 days. It feels very slimy and comes apart quite easily. The consistency almost feels like slime around a piece of string, but the second you touch it, it...

Last two weeks my take has been taken over by this ugly stuff and I’m not positive what it is and I do not want to take action if it is the wrong ID and course of action. If anyone could help me figure it out I would greatly appreciate it! Thanks in advance!

I brought in a cleaner crew refresh from Reef Cleaners and they are helping me get this algae under control. Corals are looking nice and fluffy. Just trying to get things back in balance after overfeeding the tank the last month dealing with damsels. I caught 3 of the 6 using the fish trap...

I've been having the Algae grow and i cannot identify it! I don't thing it's cyano because everything I read says it's green in freshwater aqariums but blue/red in saltwater aquariums. I dont know if I'm right or wrong but I recently changed from the red sea marine salt to the Coarl sea salt...

Hello guys! Needing some help here… Any thoughts with the light parameters and other things I should do to eliminate that algae? It is a 25 gallons with a AI Prime light. Thank you!!

Hi Experts Please help to identify these and how can I eradicate? Thanks in advance. Regards Sid

Hello all, As the title says I just got back into saltwater after about 10 years. This algae whatever it is is winning the battle because I am out out idea's my water parameters are near perfect though about a week ago I added some calcium supplement (for my halimeda plant) and misread the...

Hello fellow saltiness, I know barley straw is used as an algae inhibitor in freshwater (especially ponds) because it releases H202. 3% hydrogen peroxide dosing is also used in saltwater for the same purpose. Has anyone tried barley in a mesh bag in saltwater or are there other things released...

Hey all, I'm new with reefing and this is my first algae bloom that wasn't diatoms. At first I thought it was just a heavy case of them but they seam more maroon than rusty color like I've been use to seeing and they have these little strings forming and trapping little o2 bubbles up in the slab...

Hello all, I recently was out of town for roughly a week and a half, and I had my 75gallon tank mostly automated, but just needed a friend to help me out by changing out filter floss and feeding my herbivores. Long story short, I came back to a tank full of algae. Turns out he didn't change...

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:
