I had a 9325K bulb on my tank and shortly after I added it I started getting algae. I just switched it to a 6700K bulb, so we shall see. Frequent scrubbing has kept it under control until I was able to change the bulb along with not dosing Flourish anymore.

20 gallon long: 3 adult Neolamprologus similis + about 11 fry of various ages; low light planted tank
20 gallon long:2 freshwater dwarf puffers (Puff Puff and Poofer); medium-light planted tank
10 gallon: 1 male betta named Wormy; low light planted tank
10 gallon: 1 male betta named Dante; low light planted tank
2, 5.5 gallon tanks that are currently empty (I see more fish on the horizon )

Not trying to take over thread, just a very similar tank and problem. :)

Question about the lighting. I have the same lighting. the T-5 Extreme. It has 2 bulbs in it one is the 10k and the other is the daylight bulb. Is it still too high of a lighting? Thought for planted tanks you wanted the high lighting. Saturday morning I woke up to brown algea on tank and on plants. :( I have a 46 g tank so a little smaller then BigK_54's tank

I think the lights are being left on too long. 12-14 hours pending on when I get home from work. Planning on getting a timer today. How long should they be on?

Oh and Bigk, did you ever get your brown algea problem controlled?

Yes change the bulb(s). You want daylight 6500-6700K range. Duration of light depends on the tank and conditions. I use 12 hours but some use even less time.

so I want daylight 6500-6700k range for Each light in there? Wouldnt that lower the W/g?

and what do you mean by conditions?

Sorry I am new when it comes to lighting systems. Still reading and learning as much as I can. :-/

Yes. I would change each bulb to be a 6500K "daylight" bulb. I bought mine at Menards (Lowes or Home Depot equivalent) The wattage should remain the same. My fixture uses 32watt t-8 bulbs. The "Kelvin" rating is more the type of light than the intensity.

Conditions are water temp, tank size, CO2 or not, ferts used and the amounts, type of plants and the amount of algae you get. I just went through this last year for the first time. With my 55gal tank I started by changing the fixture from 40 watts of light total to about 96 watts. I then added Seachems flourish and Excel, added plants and set the light to be on 14 hours a day. After a couple of weeks the plants really started to take off. After about 4 weeks the algae started to take over. So I reduced the light to 12 hours a day and added more plants. I remember reading that algae tends to grow if you have excess nutrients. The idea is to have enough plants to use up the nutrients so that the algae starves. I was lucky because now I only have to clean the algae off the glass about once every 4-6 weeks. But it all starts with the light. You have to play around with the duration of light and amount of ferts to use as you go.
I also want to mention that even after doing all this, there will still be plants that won't do well in your tank because of PH or the lack or abundance of some other element. I just tried different plants until I found the ones that grew in my tank.

Good luck.

Neah.....No hi-jack here, sounds as if we have the same problem!!!! And no I still have the (colorful medafor) in my tank! Just when I think that I have gotten rid of it BAM there it is again! Ive gone about a good week/ week half now and it seems to be gone!

As for the lights. I switched out my 10000k bulbs for some 54watt T5HO 6,700K Daylight SlimPaq. Was that a good move? I see most are mentioning 6500k bulbs. I agree with WisFish on the plants per water parameters though. I have some plants in my tank that are doing FABULOUS (anacharis, whisteria (grows like a week just no where near the leaves that you see in photos), banana plant)! But I have a chain sword, microsword, and anubias nana that don't grow worth a darn and are going to hit the garbage here in a week if they don't perk up. It's just really frustrating getting nice plants and watch then die :( I have started adding Sea Chem flourish 2x a week to my tank and it seems to make a drastic difference in the week that I have added it to the plants that are doing well!

Since WisFish brought up the CO2 issue, I currently don't use it and have looked at it but man that price just scares me! Has anyone ever used Freshwater Planted Aquariums: Red Sea Turbo CO2 Bio-System

Thanks everyone that has helped myself and others with this issue, I thought I was the only one that has ever had this prob for the longest time!!!

bigk we have basically the same tank, lighting and issue so no worries on the hyjack. :) I think I know what caused my bloom over night. I did a water change and added some fert to the tank, Didnt know that when my dad was over the day before he added some fert to the tank thinking the plants needed it. so there was way to much fert in the tank for the few plants I have in there. lol That along with the lights being what they are caused it to be a diatom heaven! They havent spread anymore but havent gone away 100% hoping to get some shrimp and a few small snails in there *before the dwarf puffers arrive* :) then ill have to think of something else lol.

Still scraping glass and rubbing the plants gently so it doesnt build up.

My Anubias nan hasnt grown but its still looking very good. It might have grown hard to tell. I just added a microsword and so far its still looking healthy. but I will give it a week before I really say its healthy. I also added some dwarf hair grass and I have some java fern in there. :)

I am with ya, the price for CO2 scares me too lol especially when I don't have any money to spend on equipment right now.

I have a small 10 Gal. tank and it started getting the brown algea too. So much so that I was trying to clean it off the glass and then it started growing on my gravels. I couldn't figure it out since my tank was in a VERY dark room and my bulb is low wattage. I just moved my Albino pleco (very small) from another tank and the next morning I woke up and it was ALL gone!
