Algae and phosphates
Do any members know the ramifications of phosphates and algae growth?...........I use all rena XP filters on my tanks and i wondering if i get the phosphate remover media if this is gonna help with slowing algae growth

I've been told phosphates are a huge contributor to algae growth. I was experiencing huge algae issues, had my water tested and had a zero phosphates reading, so it was back to the drawing board for me.
Have you tested your water for phosphate readings? You may be like me and have a zero reading and may need to plan a different strategy in your attack against the algae.

I've heard the same thing as Aunt Kymmie. But remember that you'll never completely get rid of algae. How often do you have to clean it right now?

Unfortunately i have to clean the glass about once a week..........and the kicker is that this tank is seen from 3 sides....its used as a room divider in my basement.....Im planning on having my water tested for phosphate tonight at Petsmart (i dont have a test kit for phosphates) Ughh!.........I know i cant get rid of it all, but its starting to cover my plants just a little too much for my taste

I think needing to clean the glass once a week is typical and should be standard pratice. I use a mag float and run it across my acrylic daily. This helps beat the algae back so that when I do my weekly water changes the scrubbing I have to do ends up being alot less vigorous than it would be if I wasn't using the mag float daily. I highly suggest that you look into a magnetic cleaner. It's a very useful tool and is quick & simple to use.

Get your phoshate tested. If the algae is due to phosphate you'll know it'll be a simple matter of removing it. If it's not phosphate caused we'll come up with a different plan of attack. :-)

Kymmie i do use a mag float for the glass........The part that really bothers me is not the algae on the glass, but what it is doing to my plants............My one sword is starting to literally be covered in algae, its still growing but all the older leaves are covered.............Hoping i can find a solution....Thank you for your input...........Well im of to Petsmart.........I hate going there and looking at there tanks, i find it depressing

I didn't realize you had live plants. Here's what I'd focus on:
- water temp (76-80)
- amount of fertilizer used. (depends on tank. might want to reduce dosage)
- light bulb quality (6500K/6700K bulbs)
- light duration (8-12 hours today. depends on your tank and plants)
- Quantity and type of plants.

When I first increased my light and ferts, I had an algae problem. Then I remembered what someone on this forum said. If the plants can out compete the algae for nutrients, then the algae will be under control. So I added more plants and the algae growth slowed down. My I use the magna float once every 4-6 weeks. Try the wisteria.
