I started a thread in the algea forum but haven't gotten much feedback. Here is what I wrote.

I recently started up a new tank. It's a 20gal high with black fluorite substrate. I have a 65W 10K/6.5K light on it. I've been dosing PPS pro per the thread there for a 20gal and have DIY CO2 and recently started using some excell to help even it out. I would call it medium planted, I'm waiting on a few more plants to finish it up. I used some mulm from an old tank and an filter from the old tank as well.

It's been set up for 3 weeks or so and I've got algea all over the glass. I'm not sure if it green dust or green spot. The spots are smaller then what i think green spot is but it sticks to the glass so I'm not sure if it green dust.

I don't mind a little algae but this stuff is all over the glass and starting to build up on my anubias. Any help would be greatly appreciated.

After some further reading and comments I think it is GSA but am not sure how much KH2PO4 I should add to my solution to help.

Can any of you PPS-Pro gurus help me out.

change lamp to 4,5 - 4K

Hi,
It is a new aquarium so you will see more algae come and go. Patience, cleaning, more plants and some floating plants help establish this new set up. Light of this size should not be on for more then seven hours a day.

As far as changing the light to 4.5k i don't think that would do much. from everything I have read it seems that 10k is still a usable spectrum and so is 6.5K. I got the mix because I like the colors it brings out.

Over the weekend I did scrub down the whole tank to remove most of the GSA. I also decided that I should reduce how long the lights on on. Edward your comment seems to make me think i had the right idea. So right now I'm on for 4 hours then a 2 hour off period then on for 4 more.

The GSA doesn't seem to be coming back as quickly this time but I am noticing some thread type of algae. I may try to get a SAE for it since it doesn't seem like my ottos or MTS are eating it.

Thanks for your guys help so far.

Is there some reason you're doing a split photoperiod?

I'm doing a split photo period because I like to enjoy the tank when I'm home, in the morning and late evening. I haven't read anything saying it is bad to that yet but I am pretty new so maybe it isn't the best thing.

I'm having the exact same problem. I also used to run a split lighting period for the same reason. 30gallon 96w pc, with pps pro

Does used to mean you had problems with it?

I really started using a split lighting period because of a bad algae bloom and then left it because I wasn't home during the day to see the tank. Electricity is expensive here in orlando (bad months are $160+ in a 2 bedroom apartment). I'm home during the day more now so I switched back to just a continuous lighting period.
Giving the lighting a break in the middle of the day didn't seem to do much for the algae problem but phosphate absorber did help quite a bit. Phosphate absorber is out now though since I'm dosing phosphate as part of pps.
