so i've had a very slight algae problem. this week i cut back from 10hrs to 8hrs. and now my problem is getting worse. whats up with that?
less light = more algae?
- Thread starter timwag2001
- Start date
we need much much much more information.
What type of light? how much light(wattage)?
Size of tank?
Water parameters?
type of algae?
fertilizer dosing?
2 hours cut back on your light might just not be enough, do you have co2?

sorry. everything is in my tank set up
parameters are n 40-80ppm, p 2ppm,
i dose all of my ferts except for n (it's in my tapwater)
not too sure on the type of algae. i would guess fuzz algae. it grows on my glass and is very short but just long enough to move in the current

DIY co2 really doesn't cut it for 55 gallons...you're probably getting fluctuating CO2 levels which is perfect for algae growth. How many bottles are you running?
5 bottles.
i'm hoping to be able to afford pressurized next week. but there is always something else to buy that's more important

I'm thinking the move to pressurized will help your plants out compete the algae.
What's your fert dosing schedule like?
Your description sounds like BBA.

the only fert thats on a schedule is K. which i dose 10ppm everyother day. all other ferts i test and dose accordingly
when you say p you mean phosphate? i think your phosphate is too high for the conditions that you have. you can 'starve' bba by lowering phosphate cutting back on light (8 hours of 2 wpg should be good).
i agree that your diy co2 fluctuations are going to attribute to this a lot as well.
how often do you do water changes? what % water do you change?
