This is your planted tank, correct? Chemipure is not a good choice for a planted tank as it absorbs CO2 (needed by the plants). Purigen would be a better choice for chemical filtration in a planted tank- it mostly aborbs just organics like tannins and ammonia.

If you're also having hair algae issues then definitely something is not in balance currently.

Are you dosing ferts?

What's your photoperiod now?

Could you post a pic of the tank?

I've had Rosy Barbs that cleaned up the BBA in my tanks in the past. I also understand that Nerite Snails will devour BBA. (Of course, it's always more desirable to determine the cause of algae growth and adjust accordingly.)

I adjusted my lights to five hours a day I'm thinking of making it about four hours I was doing six hours with a three hour break in between that diddnt seem to work that well.
I stopped dosing Aqueon liquid fertilizer,co2 booster I was planning to add some root tabs its been three months since I added the first dose.

What liquid CO2 product were you using?

Seachem's Excel is very effective against thready algaes like hair algae. As well as being a good carbon supplment for plants. I think you need to DOSE ferts in this tank, not stop dosing ferts. It may just be the angle of the lighting in the photo, but if that anubias is as yellow in person as it appears in the picture, that's definitely nutrient deficiency.

Do you have the option of pulling your fixture up higher off the tank?

I use Aqueon Co2 boost and the light is making the anubias look yellow,but One of other anubias two of the leaves are yellow at the tips its been like that for awhile now.
No I can't raise the light any higher I heard you can overdose with exel for algae I'm going to start dosing again and add some root tabs.

Yellowing tips is a sign of Iron deficiency. But since you are battling algae right now, dosing Iron would be a bad idea. Once the battle is over (wow, it's been a while) you can start dosing but test for appropriate levels.

I don't think there is an iron test.

If you're using Excel, just follow the directions; dose 2x the "normal" amount for algae treatment. Or you can use a syringe or medicine dropper and squirt the Excel directly on the algae.

I started dosing liquid co2 and liquid fertilizer gotta head over to the LFS for root tabs. I'm also thinking about adding some floating plants like frogbit or float some water wisteria.
Yea Gary its been a long time been lazy about it for awhile I should have gotten on it before I got the fish and maybe rescape the tank added more plants especially faster growing ones.

Yeah I hear you, I've been in the same situation as well. For the next time though...

Hi I thought brown green algae was a diatom. I am having trouble with it in a newly set up tank. I have a canister filter water flow is good. Even where the flow is the BGA is growing.

Diatom algae is a part of the new tank syndrome. Right now there is an imbalance in the tank while it settles, therefore making conditions ripe for the algae.

With age and maturity it will naturally disappear. Manual removal works as well. The only time I would be worried is if isn't going away.
