So I have been battling hair algae. I cleaned the tank Sunday and have just been running blues and haven't noticed the algae. Will just running the blues cause my corals to not grow or any problems to the fish?

some people say there are long term problems but that is just from only blues for months to years at a time

Only problems I can see is when fragging and selling or giving to someone that runs something more intense, they need to know what the stuff was grown in so they dont shock it to death.

You need to get to the real root of the problem and not try and bandaid it by running only blues blues will not provide all the spectrums your corals are used to so in a way yes you will shock them a little it will affect growth it will probably slow down.

top producers of GHA
over feeding-we all do it
phosphate in the system- some rocks are full of it
bad water filters- check with tds meter
equipment not functioning properly ie skimmers not skimmin
the easiest way to get rid of it is macro i use cheateo if your not ripping it in half and throwing away a foot ball size chunk every 2 weeks get diff fuge light 6k metal halide is the best cfl/s are okayish i suppose leds not impressed....

I've heard that few supplies will put there coral under blues light all day and night a couple days before shipping. Not sure if it's but

its for coloration only i used to run 2 reefs both with halide one was ushio 6500k and the other phoenix 14k i used to buy large100-200 polyp zoa rocks froma store in parker i would take them home and split them in half one for each tank the stuff in the ushio tank grew 3x as fast as the stuff in the 14k phoenix tank but the corals in the 14k tank looked better as they had alot more color

It is my frag tank. I have mostly zoas so I don't run a skimmer. I feed the tank every other day. I have chaeteo and throw a bunch away. I am at capacity in the tank with Corals. It is really strange because the algae only grows on a couple plugs here and there. It isn't in the entire tank. I am cycling my second frag tank which will have a skimmer. This is my bandaid until I can get the other tank going well.

you just said your answer........ it only grows on a few plugs those plugs are probably loaded with P04 depends on what they are made out of i have had some before that grew algea like crazy if its a concrete plug it might have some rhyolite in it which has tons of phosphorus

Interesting. I will watch and if the same plugs get it. I'll cut and glue to others

Never realized any problems running blue only. Well, I guess if I wanted more gha it would be a problem... I recently pulled all but 4 diodes off my white side on my led fixtures to use the same 3 fixtures to double my blue wattage. Worked like a charm and still think I have too much white in there with only 12 10k white diodes

If you don't want to run a skimmer Chad do an algae scrubber. Works better than any macro in my experience. Cfl bulbs in a cheap garage reflector works great for lighting. Plenty of us run cfl or led extra fixtures over the sump with nice low electric bills, no excess heat and excellent plant growth.

How does one build an algae scrubber? Im not super handy

Basically just a PVC square base, 2 legs up and a tube across the top. Pump h2o in and it flows out through a slit cut in the bottom of the top tube, down a screen of cross stitch..... Uh..... Screen. It's a simple design. Place the reflectors with 40w equivalent cfl on each side of the screen running 16-18hrs/day. GHA grows on both sides and starves the algae in your display for nutrients.

Should I ditch the chaeto or leave it? I think I have a good idea of how I am going to build this. I hope.

Do you have a pic of this contraption?

Okay so my thought is that I will make it out of PVC because I assume it needs to be out of the water with just water flowing through it. Is that correct? I will build legs for the bottom and then PVC across with a slit in it. The PVC will then have a mesh connected to it that the water will flow. I hope this is right. Thoughts? Ideas?

I do. I'll probably make a variation of this one next and eliminate the need for an additional pump. I'm thinking of just using gravity and the outlet into the sump for the water flow.

No water pump but need air pump. Water pumps are more quiet than air pumps in my experience. Both designs have their benefits. Square inch wise of growth material, the waterfall will export more nutrients plain and simple.

Original post edited after I watched the video. I saw up flow and pictured something else then I watched.

Adding a T and two ball valves to be able and adjust flow coming out of the drain lines from the tank would be the best option. First chamber ATS the. Filter floss then skimmer and then return pump I think would work great. We could use that middle chamber of your sump for the ATS and just reverse the flow of the entire sump.

Plus with the 50 billion in and outlet holes I could even run loops in, out and around it!

I had the same problem -- tons of growth on plugs but I think it simply came in on them. I fixed it by stacking egg crate in a tupperware container, filling it with hydrogen peroxide so that it just covered the plug and then put my frags in that to sit for half an hour. 95% of the time it only took one treatment.

After I removed all the GHA from the display tank I installed an algae scrubber and it's a rare day when I see GHA in the display anymore.
