Guys my 28g jbj has been up for 2 yrs now and everything is o.k except that i get a green dust on the glass everyday!!! I have 2 clean the glass every 2nd day or it looks bad. The only skimmer i have is the stock one, i run phosguard,purigen and FF in the media chamber and have 3 or 4 turbo snails. I only have 2 clowns and corals.
Is this a algea and how do i get rid of it??
Have bad flat worms to but thats another topic...dont use flatworm exit, it nuked my tank almost. I t did kill most of the worms in 20 minutes though. LFS guy had to rush me some mixed water to save all my livestock except fish and stone polyps.

I get the same thing. It is probably nothing. I dont have any other problems. maybe someone will help us both out, if there is a problem

its algae and it seems your bioload and filtration/medias are acceptable. Honestly by now the tank should be well daily glass algae dusting. How often do you do water changes and have you tested your water source for phosphates? what kind of lighting (pc or MH jbj) and whats the light cycle? running my biocube 14 lights 5hrs a day instead of 8hrs a day was the difference between daily and every 4 day glass cleaning. how much and often are you feeding ( my two clowns and coral banded shrimp in the biocube get fed the tip of a butter knife worth of frozen every other day).
ps: flatworms release toxins when killed. Killing mass amounts (like with flatworm exit in a tank overwelmed with flatworms) will nuke any tank. its not the flatworm exit, its the dying flatworms which is why siphoning as many as possible and using natural predators should be done first and 50-100% water change and heavy carbon use is standard operating procedure after using flatworm exit. the flatworm outbreak would lead me to believe the algae problem is nutrient related.

do a 50-75 percent WC every three weeks. I do use reef trace and reef plus to dose with and i feed a pinch of oraglo every day and frozen shrimp every week...im not over feeding. I use purple up also. I just changed all my stock jbj HQI lights 2 months ago, maybe three.
Im thinking about taking all my corals out, doing flat worm exit again and after 30 minutes do a 90 percent WC...think that will help flat worms without hurting my tank so bad?
I run my 150w halide and 36w actinic 8 hrs a day....that too much?

my bet would cutting down the light cycle will help ALOT. Try running the actinics 1hr prior the halide, then the halide for 4hrs and finishing up with the actinics for 1hr or just running everything 5hrs instead of 8hrs. running a magfloat across the glass every 4-5days or so is to be expected and even every 3-4 days is acceptable.

150w halide on a 28g, wow, that seems like over kill, lol. But hey, if it looks good, whatever


um thats a stock light, talk to jbj about it being overkill. Maybe they can help you out on figuring out why they done it that way?
