the info giving is to complicated. Its simple, you have an excess of nutrients in your water column, its not the bulbs at all. Feed less, skim more, issue solved. Start dosing vinegar or growing chateo to remove the excess nutrients. Skimm wet and reduce your feeding to every second day. It will solve itsefl, something probably died, you overfeed, or your introducing something negative to your tank.

Hi Anthony. Its a fairly new 150w 14k DE.

Not dino. Thanks. Its just film algae on the glass, {green} and shows as a brown type on my rock. Both easily wipe off.

The info is not to complicated. I have been at it for 35 yrs. and reefing for 20. I think everyone is just offering their experience with algae problems, trying to help me find the solution.
Yeppers something did die. A whole whack of acro,s. Not going to light my sump for algae. If I did something like that I would use my ATS thats sitting in the shed. Of course thats not a likely scenario in the small room my little tanks in. For sure a refugium/algae filter is a good idea. Its just not conducive to my current set up. I am skimming wet.

As for feeding, I have been feeding the same way for ages. I do overfeed, no doubt but am a believer in it. Of course filtration needs to keep up. My clowns are 8yrs. old and have been fed the same way everyday. I,m watching it a bit now though.

So I dont think its feeding related but watching the amount that goes in for now. My skimmer gets dumped almost daily. I have never used vodka, {well at least for an aquarium}. I will most likely use pellets if following that route. I have read most of the sps vodka dosing threads on RC.

I started 200ml gfo last night and removed my remaining two corals to a friends. Just had the lights on for a couple hrs. today. Poor clowns are confused or spawning again, not sure which. :lol:

Its definitely not a standard nutrient build up in a tank from to much feeding or insufficient filtration. At least I dont think it is. Something is or was introduced into the tank,
either from the salt mix/ro water
the co-op water
the pollution from dead stinking acros.
something wrong with this batch of carbon/gfo I was using.
last but not least, I dont have a clue....:lol:

Thanks for the ideas people.

get a robosnail lol hide the problem set it to clean every day before you get home... j/k i hope it clears up for you i get that pesky dusting on my glass every day as well i thought ozone would help but it just cleared the water not the dusting. i was thinking it may be from the sand. but yesterday i noticed some cyano soooo ill deal with that first

Hmmm. A robosnail sounds good. Actually I need more snails but living here in Timbutoo, I cant buy any. Have to order somewhere or drive 2hrs.

I would think ozone would help with that. I have not used it in ages, but know several reefers that run it on their reef tanks.

I think I would try the bio pellets now instead. Of course thats just going by what others have posted here and on RC.

:doh: So the solution was simple.

Not sure if the pollution came from the sps tissue recession or its what caused it. However a couple days of a Phosban reactor and a proper GFO, has all but eliminated the problem.

Go figure.

Putting my SWC sump back in and it will have at least one Phosban 150 reactor for carbon and perhaps another for the beads, depending on what new fangled thing-a-ma-jingy, Ian is inventing.

Or still thinking of the NextReef shorty. I cant see why it wont tumble beads just because its wider?

Oh and by the way Chris. I did turn up the skimmer for an even more wetter skim mate. Over 3/4 cup per day of stinky tea coloured doo-doo. Thanks.. :thumb:

well its about time get your money over here and get the rest of your corals

AWESOME! Good to see its all cleared up now. I guess you might have put me over the edge for picking one of those Phosban Reactor for my own tank :)

I have heard those bio pellets worked wonders and its good to hear another success story!

Glad to hear you got it all figured out Doug :biggrin:

Thanks guys. Almost had the 20g running. Just to clarify a point Wayne. No beads in my system yet, although its a sure bet there will be. Its a regular gfo, Phosban type stuff that I,m using still.

Thanks Christy. Sure would be nice to know wither what caused the sps loss and if thats what created all the phosphate or visa versa. I guess it remains one of those never solved reef keeping mystery,s. :smile:
