Algae problems

Welcome too 3reef Nautoncall I Think your Alk is fairly low,and the calcium is a bit high.I run my alk at 8 and calcium at 440 if i let my alkalinity get lower than 6.Most of my corals would die from the bases and damage on the tips.

 

The picture doesn't give me that 'I have a bad algae problem' feeling. It looks like there's some coralline on the rocks, and some patches of green on the sand that I cant get a clear view of. I'm probably looking at the picture the wrong way, but I'm sure you wouldn't start this thread if you didn't feel there was something different going on. It is green hair algae, sort of stringy, or is this stuff slick to the touch and clings tough to the rock. I'd hate to ask for a close up photo but that may be necessary for a positive ID. All your parameters, Except as papareef pointed out, seem to check out, but keep in mind that if there is an algae problem, that will mask your Po2 reading.
Sorry to hear about your shrimp and FS dieing. How long did you have the frog spawn for? Was it there before the light change?
Keep in mind, if your system if pretty balanced out, your CUC will become it's own competition for food, and some will die off. It looks like you have a biocube, so not having that size of tank I'm not familiar with the amount and type of cuc you should have, but if you contact John at Reefcleaners.org, he'll set you up with a custom CUC for your set up.

I'm curious, are you doing any water changes, and if so, how much and at what frequency. Also, what are you using for top off water? RODI is the best choice.

 

Welcome to 3 Reef!

Tank doesn't look too bad.

Try NOT to get any more fish in that 30G! That will help long term too.

Keep working on getting the nitrates down, and the Alk up a tad.

 

I'm glad others agreed, I don't think it looks like a bad algae problem. You may just want to siphon off your sand, your rock looks pretty typical...I don't think anyone is going to have no green on their rock.....at least not until your coralline really takes off to cover most of it....

 

I had a algae problem in my tank when i first started it. i decreased the the time the light was on and the algae went away. i cleaned my glass regularly but now i rarely need to. another thing to is where are you getting your top off water from? it should be de ionized.you can get one from your lfs. thats what i do and it really helps with algae. don't put tap water with stress coat in your tank because there are all kinds of unneeded things in there.

 

The frogspawn was starting to die before I changed the light. I didn't have the algae problem before the light. Everything else has been the same for the entire time I had the tank. I did start getting water from Walmart from one of the Prime fill units. I had perviously always gotten it from either Publix or Windixie. Could that be it? I am going to replace my CUC and my filters. My anemones seem to love the new light as they almost take up the whole center part of my tank when it's on. I've used the same salt, same food, etc.

55gfowlr....it's slimy green algae on the glass and rocks. There is some "hariy" type algae on the sand but mostly slimy green. I can take a papertowl and wipe off the inside glass and it be all over it. I did an 8 gallon change a couple days ago and cleaned off the glass and today it was 50% covered in green algae. Also, I did go from a 15K light to 20K light. So how much time should I turn my light down. It is on 9 hours now.

Thank you all so much.

 

Well, after reading up, I found that cyano bacteria can come in green color just as it can red. This is due to the light spectrum it receives? If I've read wrong there someone please let me know. Now, if it is truly cyano you are battling, and my gut tells me this is what you have, then increasing your flow and make sure you don't over feed will win that battle. I started using spirula flake in my tank and every animal loved it so much there wasn't anything left 10 minutes after feeding. Any leftover food will become a cyano paradise. Does the algae seem to dissipate after each night, then rebuild during the day?

 

Hey, 55g, you might be right. I was not at my office all weekend and when I was there on Sat, the glass seemed to be covered. Today it seemed less not more and of course I didnt feed all weekend. I used my float magnet and the stuff is harder to clean off the glass. I had to scrub hard. I use flake and pellets and everything seems to devour it. I think with my snails and hermits and everything dying, that may have added to the problem. Do need to clean out all the empty shells lying on the sand? I've got a CUC ordered.

 

The hard to clean stuff is coralline. I have that in my tank. Use your mag float to get what you can, use a razor blade if it's a glass tank to get the rest. The shells don't have to get tossed, I leave them in for decor', and spare hermit homes.
