Green algae battle

So Ive had my 37 gallon setup about 3-4 months now and I am getting some beautiful coralline buildup, but am battling this horrendous green algae that continues to cover the sand. I have a sand sifting star, 5 nassarius snails (just purchased thursday to help out), and a serpent star that doesnt seem to be helping out the situation, and instead being pretty lazy. In addition to this I have about 20 turbo snails and 7 or so blue legged hermits working the tank. I am really not into the whole sea cucumber deal, but this stuff is really bringing down the view of my tank. What can i do to rid this stuff of my tank. I was considering another sandsifting star but have been unable to make it to the lfs lately.
 
This is probably hair algae and its the natural part of the cycle. Ok so here are the questions:

ammonium
nitrite
nitrate
phosphate
lights (type and wattage and age of bulbs)
Are you using RO/DI water exclusively?

Before you consider getting another sand sifting star, they dont eat hair algae anyway, consider taking the one you already have back to the store. Your tank is way-way too small to support one of these. Its also way too young and does not have what the star needs. O'yea it will live in your tank for 5-7 months but its a slow staring death.

If you want some thing that eats hair algae its an emerald or minthrax crab.

Here is something I wrote a while ago on this subject. But note with a tank as young as yours its natural. Now its time to lower nitrates and phosphates.


Do you have hair algae?
If you have a hair algae problem then read my cure all. I just recently took a tank off someone's hands, a very experienced reefer too, who had a hair algae problem that they could not fix. But the fix is so easy when you understand it. This is the instructions for a established tank. If your tank is under 3 months old read below* first.

Hair algae wont grow if you don't feed it.

1. Use Ro/DI water ONLY. If your not doing this then you are making a fatal mistake.

2. Pick off the big clumps of hair. Pull the rocks out you can and pull pull pull. Dip them back in the water to get the algae to hang down. Turn off the flow for the rocks you cant remove while you pick it off. By picking off the big clumps you remove the nitrates and phosphates from the water.

3. Know why it grows. It consumes nitrates, phosphates and light. Export the nitrates and phosphates with water changes and some cheto. Rember if you test says that you have 0 Nitrates and 0 Phosphates that does not mean you don't have them. It just means that they are consumed. If you have algae growing then you have nitrates and phosphates. Yea there in there.

4. Cut back on feeding. Where do you thing those nitrates and phosphates come from. If you have any really piggy fish then you may want to move them to QT.

5. Turn down the photo period by shutting the lights off and only turn them on for 6 hours a day. Most corals can handle this for a month. Just think of it as the rainy season.

6. Get a emerald and some mexican snails. Yea the big ones. They will both eat the short stuff.

7. Time. Give it 3-4 weeks then start to turn the lights to 7, 8...more hours till your back to a normal amount of time.


Done. Now I have my nano cube filled with sand, rocks, zoos and fish because I was able to follow this plan and he was not. Which is weird since he has an awesome sps tank.

*If your tank is new that is less than 3 months old then the question is not how to get rid of them but understanding that this is only part of the natural cycle of a new tank. If this happened just as your ammonia and nitrites test at 0 then its going to grow. Its the same reason because there is alot of nitrate and phosphate in the water. This would be the time to do your first water change and then add your clean up crew. They will take care of the algae along with water changes.

Remember don.t feed your nuisance algae and it wont grow.
Good Luck.
 
If the pieces of green algae on the sand bed are thick enough then you can manually remove them. I hated doing this, that was back when my tank was sort of new.

Try adding more flow towards the sand bed t circulate flow.
 
Thanks, I was considering buying another powerhead as I use a sea squirt to clean any excess detritus off rocks and although not very visible, it appears to build up quickly, especially in dead spots. I really dont have a problem with algae anywhere besides the sand bed and the filter box which i keep clean as necessary. My current flow is the return which is powered by a mag 5 and a maxi jet 900.
 
Ninjamini - Great Post and I agree for the most part.

You can also try adding a lawnmower blenny.

The only part about your post that I disagree with is that the algae blooms are a "natural part of the cycle" with new tanks.

I believe that most folks do go through this with a new tank to the point that what you say has become almost general knowledge and is believed. The same goes for the brown diatom bloom that "everyone" gets with a new tank.

I say - it doesn't have to be so. IMO, the main reason for new tank algae blooms are the use of inferior salts and or not using RO/DI water exclusively.

I filled my latest tank up six weeks ago. I have not had what most folks experience with brown diatoms. I must admit, I did see several very small, very light patches of brown diatoms that lasted for two days and was gone. Personally, I don't consider that a diatom bloom of any significance.

I have full confidence that I will not experience the green hair algae problems either.

This tank is already stocked with some soft corals and several fish. There were some xenia and paly's in the tank from day one since they happen to be grown onto rocks that I wanted to use in the scaping.

So what's the salt?

Aquacraft's Marine Environment
 
LOL - guess I wasn't quite finished.

NO - I'm not saying that Aquacraft's salt is a cure all for anything.

You can use the best salt in the world and if you overfeed, don't have adequate filtration, etc - you will have a build up of nitrates/phosphates and create a great environment for aglae to grow in.

Ooohh I love a good discussion.

Algae thrives (grows) because it can. Algae, like almost all plants, needs 2 things to thrive...food (aka nutrients) and light. If you provide lots of nutrients and good light it will grow. Algae needs nitrates and phosphates.

The importance of RO/DI water is that it has had these nutrients removed. Using tap water is very bad for the tank and if you do not have axcess to ro/di then I would say wait on getting a tank until you do. That is how important it is.

If you want to reduce the growth of algae in your tank take away its food...nitrates and phosphates. These come from fish and the food that you give them. You can also remove there light and it will wither.

Recently I added some cheto into my system and lit it with a 8 watt light. The algae shrank in size. Finally I upped it to a 50 watt light and its growing like a weed.

I agree again except for this part and I don't totally disagree with this part.

All I'm trying to say is that there are other sources of nitrates and phosphates and inferior salts happen to fall into that category. Even the majority of ones that say, "Nitrate/Phosphate Free".
 
Well i dont mix my own salt, I find it to be a pain in the *** and I leave a busy enough life as is. Soo, haha, I buy the pre-mix from big als typically. I do have bio balls in my sump (a 75 gallon proclear aquatics) and was considering removing them and putting chaeto there. My other option, which i much prefer, would be to drill two holes into a 5 gallon plastic container and into the sump, connecting the two with pvc, screening the pvc, and growing chaeto in the auxilary tank. Ive only been reefing for about 6 months, I know a DIY sump would have been critical but I cant go back now.

It's almost as if you take for granted that because you are buying the water from a fish store that it must be good.

I haven't used nor tested Big Al's water so I can't speak good or bad about it.

The water that we put in our tanks is one of the most important elements for a healthy system yet so many folks almost ignore this fact. They'll save a buck and buy the cheapest salt. They won't do a water change for a month or two at a time, etc, etc. But these same folks might drop $100 on a coral frag that they really want and then wonder why it ups and dies on them.

I don't get it.
 
what all is used/ need to mix salt?? Does it really have to be mixed around with a powerhead?? What crystals do you recommend? I think I may be feeding to much and will definitely cut down on that factor.
 
Overfeeding is a very common problem. The more you feed, the more your inhabitants poop, the faster your nitrates build up.

I certainly don't recommend starving your fish to death but feeding once a day or even every other day should be fine unless you have fish that need a constant food supply. Only feed what they will eat in a minute or two. You don't need leftovers for your clean up crew. They will find food.

I'm just as guilty as the next person with overfeeding. You can compensate for this up to a point with having a kickass skimmer and fuge full of macro.

Salt Mixing: A lot of folks just use rubbermaid trash cans to mix and store their saltwater. (these really need to be cured before using). Other folks get plastic (food grade) drums and turn them into salt mixing stations.

You need to have a good RO/DI unit (or a source for water with 0 TDS).

Yes, you will need a powerhead to mix the salt and keep circulation going. I use a Mag 12 for this purpose. The mixture needs mixed and should be aged and aerated before use. Mixing it up a week in advance isn't a bad idea.

The only salt I would recommend is Aquacraft's Marine Environment or Bio-Sea.
